Most of the reverse osmosis systems work the same way. However, their performance can be affected by different factors. They include the incoming water pressure, the quality of filters and membranes, water temperature and the type and number of TDS (total dissolved solids).The Domestic RO Plant are used for purifying contaminated drinking water. In the process of this system, the contaminated water molecules are forced through a semi-permeable membrane, which blocks the impurities and contaminants. So they are subsequently expelled from the environment to produce clean and pure drinking water. Ordinary RO Water purifiers just give you water, they are unable to give you healthy water. Only PentaPure Most Advanced Reverse Osmosis Technology Retains Essential Minerals during water purification Process which ensures removal of Harmful Chemicals , Heavy Metals , Arsenic, Virus, bacteria, Pathogens, Protozoa and dust particles from water. These bacteria's and Arsenic are responsible to spread Water Borne diseases like Hepatitis , Typhoid, Malaria , Cholera , Diarrhea, Giardia Skin & Lung Cancer . To stay healthy it is always necessary to drink bacteria free RO purified water
