Product Introduction

The reverse osmosis host system can be called a reverse osmosis device, which is the heart part of reverse osmosis water treatment equipment. It is mainly composed of reverse osmosis membrane elements, membrane shells (pressure vessels), brackets, etc. The water treated by the reverse osmosis device can remove the vast majority of impurities such as inorganic salts, organic matter, and microorganisms. The rationality of reverse osmosis system design is directly related to the investment cost, economic benefits, service life, and operation process of the entire project.

Technical Advantage
Automation
The intelligent system operates automatically and starts/stops automatically.
Long Lifespan
The system can automatically clean online, extending the service life of the reverse osmosis membrane.
Smart Alarm
The equipment has abnormal alarm functions for water quality, liquid level, flow rate, and pressure.
Lon Dissociation
Chlorine and potassium ion dissociation technology, reducing the frequency of reverse osmosis membrane replacement.
