The combination of reverse osmosis and EDI has overcome the deficiency that reverse osmosis effluent cannot be deeply desalted, and further removed trace carbon dioxide, residual salt, silicon dioxide, boron and total organic carbon plasma in RO water, greatly improving the quality of purified water.
It is widely used in biotechnology, pharmacy and other industries that must generally comply with USP, EP，JP and ChP regulations.

The reverse osmosis device with EDI (reverse osmosis electrodeionization) is the most preferred purified water preparation technology in the pharmaceutical, food and biotechnology industries. It is basically a combination of reverse osmosis and electrodeionization processes. In reverse osmosis EDI system, single-stage or two-stage reverse osmosis is used to pre desalinate EDI feed water, and then deeply electrodeionize RO production water through EDI to finally produce high-purity water required for application.
The most cost-effective way to upgrade RO purified water system (PW) to high purified water system (HPW).
Effective minimum flow interlocking and current overload protection device.
Excellent water quality performance under different working conditions.
Front and rear UV devices (optional), thermal disinfection module (optional).
PLC+HMI full-automatic control mode.
Fully comply with GMP, USP and cGMP requirements.
