From all our natural resources, water is maybe the most valuable of all for us, because without water, human body can only live during 3 days. We must take care of our water, and Sun & Climate offers different products of water recycling with this aim: sewage treatment, grey water recycling, rainwater harvesting, decalcification and reverse osmosis.
Water is a limited natural resouce without which human body can only survive during 3 days. Climate change and the bad management of our resources decreases our rivers flow and the availability of drinking water. Besides, some states are studying the possibility of increasing water prices. It is a need, therefore, to get the maximal profit of drinking water. Soliclima offers with this aim several methods of water treatment.
Due to the water shortage, society is becoming aware of the importance of recycling water. The daily household use per person is 129 liters and half of that comes from the shower and the toilet. Besides reducing the use, we can opt for recycling systems to improve consumption.
Rainwater harvesting consists of filtering the water collected in a given area, generally the roof or terrace and store it in a deposit. Later, the treated water is distributed through an independent hydraulic circuit of the potable water supply.
The water that comes to our home directly from the public water supply, has minerals and other substances that can be harmful to our body. Water purification, will provide energy savings, increased performance and longevity of appliances.
Reverse osmosis is a water purification process by means of a semipermeable membrane that functions as a filter. This membrane has small pores that do not permit the particles in suspension contained in water to pass, but do allow water molecules through.
As valuable as our forests are our water resources, essential for the proper working of the whole system and the survival of the planet.
Our planet has a water volum of 1,4 millions of km3. But only a 2,5 of it is sweetwater, and most of it is frozen on the glacials. Of this 2,5%, only a 0,4% is on the earth surface. That means that of total water on the Earth, only a 0,007% can be considered drinking water.
Climate change is already altering the climate in many places, with the result of less rain and the consequent drought. In states as California the effects will be more remarkable than in nothern states. California or Arizona will live more acute impact than Montana, for example. We have to start to be ready for it and water recycling is a possible solution for an eventual water shortage.
Allthough this is a widespread problem. Australia's southwest is living a drought that lasts already several years and has drived into the ruin to many local farmers. According to stydy of the scientific magazine Journal of Climate, some of the biggest rivers in the world, such as the Yellow one, Ganges and Colorado have been continously decreasing its flow for the last 50 years.
Allthough it goes unoticed, water is so important for the economical activity of a country as energy is. Some financial studies have already be done, and the result is that the economical sectors more affected by an eventual water shortage will be: that ones connected to high technology -because they need big water quantyties for thir manufacturing processes-,; power plants -need big quantities of water for refrigeration- and farming. Otherwise, some other industries affected are drinks sector, biotechnogy, metallurgy and mining. The CEO of Nestlé has said: "Water will be exhausted before oil does."
Some countries have already given an alert. Sudafrica, that depends exclusively on the rainwater for their drinking water supply, is studying the possibility of recycling used water and create desalination plants to warranty the drinking water supply. Australia is also regarding this posibility, due to the drought they are already living.
As consumers, we cannot open our own desalation plant, but we can take some measures to save water:
