Rain of Life at the Havana International Fair FIHAV

One of the most important international trade fairs in the Caribbean and Latin America, FIHAV, was held in Havana (Cuba) last November. FIHAV.

This fair, which has been held since 1983, aims to be a center of commercial exchange of relevance in the Caribbean, bringing together a large number of exhibitors, businessmen and technicians from all sectors of the Cuban and international economy.

Rain of Life participated in FIHAV with its commercial partners Elettrica Vicentina S.R.L. and Solintel S.A. in order to share with all participants in the fair the possibilities and operation of atmospheric water generators and solar panels. In addition, the project was awarded the Gold Medal for the quality and rationality of the project of this 38th edition of FIHAV.


Great expectation at the Fair

The site where the RoL50 equipment was located was visited by many of the attendees at the Fair. Important personalities such as the Vice Prime Minister Dr. Jorge Luis Perdomo Di-Lella, the director of the Finlay Vaccine Institute, Vicente Vérez Bencomo or the president of BioCubaFarma, Dr. Eduardo Martínez Díaz received from the director of Rain of Life, Mr. Javier Sanchez Alejo the explanation on the operation of the equipment. During the demonstration, they were also able to exchange ideas about the advantages of these revolutionary drinking water collection systems for tourism or for the health and biotechnology sectors.


A partnership for progress

The commercial alliance between Rain of Life and its partners in the Caribbean aims not only to open the doors to the Cuban market, but also to raise the possibility of manufacturing the equipment on the island for distribution to other parts of the Caribbean. Rain of Life atmospheric water generators offer optimum performance in places with high temperature and relative humidity, making the geographical area of Central America an ideal location to get the most out of the equipment located there.

Rain of Life at the Exphore Costa Rica trade show

In our continuous effort to show the qualities and benefits of Rain of Life Atmospheric Water Generators, we recently participated in the Exphore Costa Rica fair, an event aimed at the hospitality world, mainly hotels and restaurants, but also attended by professionals from the supermarket sector, the food industry, caterings… More than 4,000 people, mainly industry professionals, attended this event encouraged by the interest in the new products and services that the more than 200 exhibitors had to offer to their businesses.

The fair was held in San José on October 25, 26 and 27 and Rain of Life did not hesitate to confirm our participation.

For restaurants and hotels, having an abundant supply of quality drinking water is essential. They usually have a large number of users among their guests or diners and the staff itself, and drinking water is one of the most important resources to offer an excellent service to their customers.

Our objective at this fair was very clear: to show in person how our atmospheric water generators work, as well as to show directly what they can do for each of the sectors that gathered at the Costa Rica Convention Center.

One of our equipment, specifically the RoL50, was installed at the exhibition to demonstrate its ease of operation and dimensions. In addition, trade fair attendees were able to see how our atmospheric water generators extract high-quality drinking water from the humidity in the air.

During the two days of the fair, the Rain of Life team in Costa Rica was able to present our equipment to hospitality professionals, as well as recommend the one that best suits their business. Each machine offers different delivery capacities, from the 50 liters of the RoL50 to the 10,000 liters per day of the largest machine, the RoL10,000.
It was a pleasure to share these days where networking and the discovery of new products and services to improve the efficiency of a sector as important as this one were the protagonists, in addition to demonstrating that a responsible and environmentally friendly water consumption is possible.

Likewise, it was possible to demonstrate that quality and sustainability are compatible thanks to the solar kits that we have designed for each atmospheric generator. In this way we take advantage of and reuse nature’s resources, thus reducing our carbon footprint and also saving on our electricity bill, which is always appreciated by the sectors visiting the fair.
It only remains for us to thank Exphore Costa Rica and all the attendees who came to this fair for the great reception of our stand and the interest shown by all those who passed by it in the possibility of obtaining an autonomous and economical supply of drinking water of a higher quality than most bottled water on the market.

And of course, from Rain of Life we would like to give special thanks to the Rain of Life Distributors in Costa Rica, Mr. Rubén Ruibal and Mr. Rubén Dorta for the excellent work done in Exphore, with whom all the people and professionals in Costa Rica can contact for any further information they may need.

The Venezuelan military deployed in Paraguaná are supplied with water produced from the air.

From September 19 to 29, more than 2,500 Venezuelan military personnel were deployed in various camps on the Paraguaná peninsula (Venezuela) for strategic training as part of the 17th anniversary of CeoFanb.

The event was attended by representatives from 25 Operational Zones, divided into camps that were set up in each zone with all services. For this purpose, drinking water was supplied to the personnel deployed there through the installation of several Rain of Life atmospheric water generators.

The equipment installed there came from the Punto Fijo plant in Falcón State, which was inaugurated at the beginning of the year. This plant manufactures Rain of Life atmospheric water generators for all of Latin America with Venezuelan labor.

During the military practices, equipment was installed that generated 50 liters of water per day each, thus supplying quality drinking water to all those who attended the event.

River pollution

We are aware of the water pollution problems caused by plastics that fall into the sea. They come from different places: waste dumped on public roads, fishing nets, waste from ships and commercial cargo… These plastics, reduced to microplastics, are responsible for polluting the seas and poisoning marine species. Thus, each year, more than a million birds and more than 100,000 marine mammals die as a result of this invasion of plastics in the sea.

But there is a problem of similar magnitude that is beginning to gain prominence in the concern of scientists and biologists, and that is drug contamination in the water of rivers around the world.

A study published by PNAS on 258 rivers in 104 countries around the world shows that the presence of pharmacological pollutants represents a real threat to environmental and human health in more than a quarter of the places analyzed.

Environmental exposure to active pharmaceutical ingredients can have negative effects on the health of ecosystems and humans, and also represents a global threat to the achievement of the UN Sustainable Development Goals.

Pollution of rivers by drugs

The problem of antibiotics and drugs dumped into rivers has been known for a decade, although some regions such as South America and Africa had not been studied until now. The aforementioned study found that South Asia and South America concentrate the majority of rivers with high drug contamination around the world, topping the list of most polluted rivers in the cities of Lahore (Pakistan), La Paz (Bolivia) and Addis Ababa. (Ethiopia). In the case of Europe, the most polluted river is the Manzanares River while, in the United States, the southern city of Dallas has the most polluted river waters in the country.

Regarding the substances that are most found in the fluvial waters studied, anticonvulsants, antidiabetics and caffeine are some of the protagonists of this contamination.

How do drugs get into river water?

The discharge of drugs into the water is partly unavoidable, since it is a consequence of our own consumption. Our kidneys work to excrete “useless” substances from our body. There are studies that indicate that up to 90% of the medicine we take is expelled intact with the urine.

But not only humans are responsible for these events; farm animals, industrial discharges or drugs thrown away, also increase the pharmacological levels of the water.

Damiá Barceló, a member of the Higher Council for Scientific Research and director of the Catalan Institute for Water Research (ICRA), points out that “close to 20% of European citizens still flush medicines down the toilet, instead of taking them to pharmacies or collection of expired medicines”.

Antibiotics and other medicines.

The discovery of antibiotics in rivers was already a known problem years ago, although in this case, scientists determined that in more than 19% of the regions analyzed the presence of these drugs was so high that it could stimulate the development of resistant bacteria. These bacteria are considered by the WHO as one of the main threats against public health, and it is recognized as a “silent pandemic” that caused more than one million deaths in the world in 2019.

Because obviously the water we consume is subjected to purification and potabilization treatments that are responsible for nullifying the incidence of these toxins, but we must think about the species that live in these waters and that are the most realistic indicator of their level of health. . For example, algae and fish are hopelessly faced with the existence of these high levels of toxins that are detrimental to their existence.

In the case of antidepressants, some studies determine that marine animals can suffer a deterioration in their health due to the intake of these medications. Giovanni Polverino, an evolutionary ecologist at the University of Western Australia, recently stated that “The collateral effects of psychoactive pollutants in wildlife are of increasing concern. Psychoactive drugs target receptors in the human brain that are evolutionarily conserved throughout the animal kingdom; so it’s perhaps not surprising that they can affect non-target species.” In other words, the intake of antidepressants by these species can affect their ability to socialize, alter their eating patterns, migratory routes and even their mating. Research published in 2021 also revealed that crayfish exposed to antidepressants present in river waters become much more aggressive, hide much less and are therefore more vulnerable to predators. This certainly affects the food chain and the cycle of life.

But does this affect the water we drink?

The Drinking Water Treatment Plants or Stations (WWTP or WWTP) have means to remove the different contaminants that they may contain from the water. To do this, as we have already mentioned in previous blogs, they have numerous “pools” through which the water passes, and in each of them a contaminant is removed by reacting with some chemical substance that the plant pours into it. However, the huge amount of contaminants from medicines, or emerging contaminants (as they are called in some media) makes it very difficult or almost impossible to find reagents that completely remove them from the water we drink.

In this way, several studies affirm that the water that reaches the taps of our houses contains certain amounts of emerging contaminants or medicines that have not been able to be eliminated in the treatment stations, and that are harmful to health. And this circumstance, as indicated, could be even more serious in the future.

However, the water obtained from the Rain of Life atmospheric generators is unlikely to contain any of these emerging contaminants. For this reason, in addition to many others, its consumption is recommended for drinking and cooking.

Understand water bottle labels

The fundamental information of any product that is consumed, be it food or drink, appears on the label. The most relevant information on its identification, description and components must appear on the label. Bottled water also has its corresponding label, which in addition to fulfilling its role in terms of purchasing decision, must respond to the need to know the type of product that is offered inside each bottle.

What is an ETAP?

When we talk about the management of drinking water, it is inevitable to wonder how water, from its different sources, reaches our homes converted into drinking water. As we mentioned in previous articles , supply systems collect water from different sources: rivers, streams, reservoirs, wells, springs, reservoirs, among others. Once that raw, untreated water is stored, that is when the ETAP .

Convert stored water into drinking water

When we talk about ETAP we refer to the Drinking Water Treatment Station, also known as the Potabilizadora. It is an industrial facility in which the appropriate treatments are carried out to precisely make all that water collected and stored from different sources become completely safe and suitable for human consumption.

How does an ETAP work?

Although its appearance at first glance is that of a perfect water to drink, the water that reaches the water treatment plants contains numerous pollutants that are harmful to health. These biological, chemical and even radioactive pollutants must be completely eliminated through the appropriate treatments.

Although there are various types of water treatment plants, normally, to achieve this end, they carry out a series of continuous processes whose generalized sequence is as follows:

  1. Pretreatment or pre-sedimentation: The water reaches a large deposits in which settleable solids are removed. The heavier particles fall to the bottom when the water movement stops.
  2. Flocculation: the coagulation or flocculation process consists of adding chemical additives to the water to promote the sedimentation of non-sedimentable colloidal matter or to accelerate the sedimentation through the formation of flocs. Flocs are groups of small particles agglutinated into larger particles with a greater sedimentation capacity.
  3. Sedimentation: Due to the effect of gravity, the flocs settle to the bottom of the tanks to be eliminated.
  4. Filtration: The water passes through a porous medium that is responsible for retaining the remaining impurities. Once this phase is finished, the water will be completely clean, although it will not yet be suitable for consumption.
  5. Disinfection: In this phase the bacterial load of the water is reduced. This treatment is carried out with different methods, either ozone or ultraviolet rays for its subsequent chlorination that will achieve clean water and, now, totally drinkable.

The arrival of water at home

After disinfection, before reaching homes, the water must pass strict controls that verify the real quality of the product obtained in the water treatment plant. Thus, in Spain, it is the National Information System for Drinking Water, the body in charge of this control and the collection of data on the characteristics and qualities of the water from the ETAP.

Once this quality is verified, the water is stored in tanks near the water treatment plants until it is transported to homes, receiving a contribution of chlorine that favors its conservation in those tanks.

Why is chlorine used in water and how does it affect health?

Chlorination is one of the processes that are carried out to treat water and its objective is to carry out a disinfection of all kinds of bacteria and pathogenic organisms. The ultimate goal of these treatments is to obtain drinking water that can be consumed by humans without risk to their health. But, is there any risk in the fact that this chemical has a presence in the water we drink? We will analyze it below.

How does a wastewater treatment station work?

One of the bases of correct water management lies in its adequate reuse once it reaches the final phase of the cycle. At this point, it requires a process and treatment before being returned to the natural environment in optimal conditions, which is carried out precisely in the WWTP: Industrial water treatment. Dumping wastewater into rivers without carrying out the corresponding treatment implies generating an environmental impact with fatal consequences. Next we will see what this process consists of.

Clean water and sanitation

Institutions such as the UN point to clean water and sanitation as one of the Sustainable Development Goals of their Development program. To meet this objective, the treatment plants carry out this work of cleaning and treating wastewater to be able to return it to nature free of waste harmful to the environment.

What is wastewater?

They are the waters coming from homes, businesses, industry and agriculture, once they have been used for the purposes that each place requires. Thus, the water discarded from the washing machine at home, or that used to cool the turbines of a factory, is directed through the sewage network to some collectors that finally end up in the purification station. Domestic wastewater contains organic and suspended pollutants while industrial wastewater can also add heavy metals and hydrocarbons. In this way, these waters with toxic substances of inorganic nature are forced to undergo a previous treatment in the facilities where they are generated before going to the municipal collectors.

Once the domestic and industrial wastewater passes to the collector, the water purification phases will begin, which aim to eliminate organic residues such as oils, fats, sand and sedimentable solids as well as chemicals such as ammonia and phosphorus. In addition, in the last steps, the retained waste will be transformed into stable sludge that will also be reused.

How does a WWTP work?

In the treatment plant, the water will go through four well-defined phases:

  1. Pretreatment: After entering the station, larger waste is removed through screening grids that retain garbage and other bulky items; later on, it goes to tanks in which suspended sand and grease are removed thanks to mechanical processes. From here it will go to the primary decanter to continue with the process.
  2. Primary Purification: In this decanter, the water will remain at rest to favor the deposit of the heaviest residues at the bottom. These residues will generate a sludge that will be separated from the water and stored in a sludge digester prepared for this purpose.
  3. Secondary Treatment: The water passes into tanks to which oxygen bubbles are added to promote the proliferation of microorganisms that will be responsible for removing the dirt that remains. This biochemical process will eliminate organic matter such as ammonium which, if it remains, will consume the dissolved oxygen available for aquatic fauna and flora once the water is returned to the natural environment. In this phase, new sludge is created that will separate from the water and go to the sludge digester.
  4. Tertiary Treatment: In this phase a settling, filtration and disinfection of the water is carried out. After this process, the water is returned to the natural environment in the best conditions so that it can continue its cycle.

What happens to the waste after the process?

The wastewater treatment process, as we have detailed, generates sludge that is collected through the different phases of this process. This matter and its biological reactions are reused for different purposes. On the one hand, when stabilized and extracted, this sludge produces biogases that are used as energy, and even as biofuel for vehicles. On the other hand, the sludge itself generated is used as organic fertilizer, replacing in many cases chemical fertilizers that are harmful to the environment. Finally, the algae and other microorganisms that proliferate in the process are also used to generate biomass, among other uses.

This interesting video helps us to understand in detail this process of collecting and treating wastewater as well as the subsequent management of this waste.

Thus, with the treatment of the water that we discard every day, we not only contribute to returning to nature that resource so necessary for our daily life, but it also arrives in perfect condition so that it can contribute to the environmental balance that we need.

The treated water returns to the natural environment, but is also used in:

  • Urban uses: street cleaning, irrigation, sanitary uses, etc.
  • Industrial uses: for example for the cooling of machines.
  • Agricultural and livestock use: cleaning, irrigation of crops, etc.
  • Other functions such as golf course irrigation, aquifer recharge, etc.

The largest treatment plants in the world

Atotonilco WWTP (Mexico)

It is the largest Wastewater Treatment Plant in the world, which treats all the waters of the Valley of Mexico destined to irrigate 80,000 hectares of land.

Stickney WWTP (Cicero, Illinois, United States)

Its 230 hectares of surface supply the entire city of Chicago and other areas and its water pumping station, lifts them from a system of tunnels to almost 100 meters deep

Bailonggang WWTP (Shanghai, China)

The main wastewater plant on the Asian continent with 24 hectares of surface, is responsible for the purification of a third of the waste that is dumped daily into the waters of the Yangtze River.

The importance of wastewater treatment

In summary, the Wastewater Treatment Stations contribute to reducing the waste generated. The recycling of wastewater minimizes waste, to which it is convenient to contribute with responsible use so that our future generations can continue to have the water resources necessary for life.

Importance of drinking water in the fight against malnutrition

The drinking water it is an indispensable resource for human life. More than 90% of the body’s functions are possible thanks to the presence of water and approximately 80% of the human body is made up of water.

The absence of drinking fountains in a community not only generates problems of civility and discomfort, but also provides the ideal setting for the appearance of gastrointestinal diseases and malnutrition .

Fighting malnutrition through drinking water

The project Generation Nutrition of the United Nations Organization recommends three lines of action to combat malnutrition. These consist of:

  1. Implement environmental sanitation policies in marginalized communities.
  2. Undertake campaigns that promote hygiene in slums.
  3. Invest in projects to improve the water quality in human settlements with very limited resources.

Of the three points mentioned above, it is the third that presents the greatest difficulties, because guaranteeing the water safety It not only depends on the human and material resources available, but it is also related to the accessibility of the geographical area to which it is intended to benefit.

Nutritional issues related to water quality

The consumption of unhealthy water is one of the main causes of gastrointestinal diseases. This frequently causes damage to the digestive system that makes it difficult to assimilate nutrients. The Director of Emergency Programs of the United Nations Children’s Fund (UNICEF) , Manuel Fontaine, states that it is impossible to guarantee adequate nutrition in people who do not have access to quality water consumption .

The most common ailments found in those communities that do not have access to drinking water sources are briefly explained below:

  • Chronic poisoning . This phenomenon occurs in populations with scarce resources that are established in places where the soils are sandy and rich in minerals. The level of presence of these substances is sometimes so great that, on occasions, the water tables are contaminated and transmit a high content of heavy metals to the available water reservoirs. The result is that the population consumes water with a high content of heavy metals, such as lead and arsenic, which are highly harmful to health.
  • Environmental enteropathy . This disease usually causes greater damage in the child population and consists of the loss of the intestinal capacity to absorb fluids and nutrients. The cause of this disease is due to prolonged consumption of contaminated water.
  • Parasitosis . This is usually an easy condition to control. However, it is very difficult to detect and, when it is detectable, the patient is usually in a state of severe parasite infestation. While this is not fatal, it is dangerous and leads to malnutrition. Like environmental enteropathy, parasitosis is the product of ingesting contaminated water.

Action plans to ensure safe water

The UNICEF , as well as the UNESCO , they state that having access to a quality water resource is a fundamental human right . Therefore, in their social improvement programs, these organizations implement actions aimed at improving the management of this resource.

Among the actions undertaken, the following can be highlighted:

  • Improvements in water catchment systems.
  • Technological research aimed at optimizing water purification processes.
  • Implementation of innovative techniques in the storage of water resources.
  • Design and construction of piping systems to distribute the liquid promptly and expeditiously.

Fight malnutrition through water quality management

Despite the great efforts made by international organizations to improve the management of the quality of water resources, there are still many challenges and needs that must be covered to improve the quality of life of less fortunate people.

In terms of water distribution and administration, some of the challenges that reality poses to humankind are the following:

  • Improve bureaucratic processes in each country to obtain the necessary resources in the construction of quality hydraulic systems.
  • Use all relevant technological advances to efficiently transport the vital liquid to those who need it.
  • Promote and implement policies that allow the implementation of water systems for human consumption.
  • Implement health and nutrition programs in relation to water consumption.
  • Undertake education and awareness campaigns in the population for the responsible management of water resources.

Apparently, much remains to be done to achieve access to safe water for all communities. It is necessary for the whole of society to become aware of the importance of proper administration of this resource and its implications for health. This is everyone’s job.

The water footprint and environmental impact

Water is one of the most important resources for the survival of living beings, not only as a basic good, but also as a raw material or auxiliary element to produce many goods and services. What impact does water use have and how to control it? The concept of “Water Footprint” responds to this and other questions about the sustainability of water use.
