RO - EDI Technology used to Purify Water

Reverse osmosis is opposite of osmosis process occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration.

EDI is a revolutionary technology for the water treatment. It uses demineralization process of electrical regeneration ion exchange instead of traditional demineralization process of mixed ion exchange DI. The resin & selective ion membrane can reach high desalination effect by exchanging the ion.

Using RO - EDI process in combination, we can expect the output water quality up to 10-15 mega ohm.cm.
