Two-stage Reverse Osmosis and EDl System

A two-stage reverse osmosis (RO) system typically consists of two sets of RO membrane units, each equipped with its own high-pressure pump and control system.

The EDI (Electrodeionization) module is an advanced water treatment device that uses ion exchange technology to remove impurities and dissolved substances from water, delivering high-purity water quality.

In the first stage, water passes through the first RO membrane unit, which removes the majority of impurities and dissolved salts. The second stage then further purifies the water by removing remaining contaminants and salts. Two-stage RO systems offer advantages such as high salt rejection rates, high recovery rates, low energy consumption, and low maintenance costs.

The EDI module and two-stage RO system complement each other to complete the water purification process.

First, the two-stage RO system removes most of the dissolved substances and microorganisms, significantly improving the water quality. Then, the EDI module further eliminates ionic impurities and dissolved organic compounds, ensuring that the ion concentration and purity of the water meet required standards. Through this series of treatment steps, the result is clean, odorless, and safe water.

When used in combination, these two technologies significantly enhance the quality and purity of treated water. They are widely applicable in industries such as electronics, power generation, pharmaceuticals, chemicals, and biotechnology, and also play a crucial role in various other fields.
