Interesting! Potable Rainwater: Filtration and Purification
Due to population growth, global warming, and climate change, water has become scarce in many countries around the world. Water levels have dropped gradually, and it has become a serious concern for the government because it leads to illnesses and even death of the citizens.
Harvesting rainwater is a simple and practical way to deal with the water crisis. As people become environment-friendly nowadays, rainwater harvesting is becoming popular.
Ways to Filter Rainwater
Traditional method using Ultraviolet Light
One way to disinfect the rainwater is through the use of ultraviolet (UV) light. This method has been used for almost a century in Europe, and now it has become popular in the United States.
The UV light works by penetrating the cell walls of the organisms and prevent its reproduction, thereby making it harmless. Also, UV light does not change the water?s chemical composition plus it does not leave any by-products on it.
The last method of filtering rainwater is through solar pasteurization. This system is labor-intensive, unlike all other methods.
To do this, fill a Ziploc bag with the rainwater, place the bad on two feet of aluminum foil, and place the shiny part on a sunny place in your home. You need to let the bag stay heated under the sun for several hours, and it should remain at about 160 degree-Fahrenheit or higher. With this, the water-borne bacteria can be eliminated in the water.
Although this method can time consuming and laborious, doing such a method is beneficial to produce clean drinking water harvested from the rain.
In sum, rainwater is free, and you don?t have to pay for it. It is one of the renewable sources of water, and it can stay for a longer period of time. However, you need to process it so it can be converted to safe and clean water that you can use inside your house, farm, and to tend your animals.
