1. Product Description                                                           / Ultrapure Water System
Reverse osmosis system is using city water as raw water, then treat water by Pre-filter (water softener is optional), reverse osmosis membrane. It can remove particle, colloid, organic impurity, heavy metal ion, bacteria, virus in water, and it can also remove 99% dissolved salt. The whole system desalination rate can reach 96%-99% to make permeated water conductivity<10 us/cm. Dense water also won't polluted environment. The second stage reverse osmosis system use the first stage reverse osmosis system output water as raw water to make water to be more pure. Normally output water conductivity<2 us/cm.
