Edi/ultra pure water machine/ro+edi(KY-EDI)
Description of this ro water system
Reverse Osmosis or (RO) can be described as a procedure whereby pure water and contaminants is divided via a semi-permeable membrane(s) with very fine pores. This method is a necessary technique employed in the majority of water purification systems. Reverse Osmosis is considered to be a highly effective approach to eliminating water impurities, such as Toxic Heavy Metals i.e. Lead and Radium, Mercury, Chlorinated Pesticides, organic matters, Turbidity & Dissolved Solids, bacteria, virus.
RO system is widely used in water treatment, purification for tap water, well water, underground water, borehole salty water, brackish water and seawater, pure water and ultra-pure water production. Application area such as, food processing, bottled drinking water, home use drinking water, power stations, electronic industries, cosmetics production, pharmaceuticals manufactories, and medical treatment(such as hemodialysis). It is a key equipment for pure water plant and ultrapure water equipment.
