Water is run through RO membrane at high pressure where it gets rid of hazardous materials such as pesticides and herbicides, heavy metals, and hardness. It also eliminates virus, protozoa, bacteria, and microbiological threats.
In this stage, water is decontaminated using UV radiation from waterborne disease-causing bacteria, protozoa, and virus.
Organic impurities like cysts, bacteria, giardia, etc. are further eliminated from the processed water in this stage. It also removes suspended impurities from the water making it clearer and richer for consumption.
Every person uses products made from minerals every day. The salt that we add to our food is the mineral halite. Antacid tablets are made from the mineral calcite.
