Two, two-stage reverse osmosis workflow

Two-stage reverse osmosis equipment is usually composed of a pre-treatment system, a first-stage reverse osmosis system, a second-stage reverse osmosis system and a post-treatment system. The specific work flow is as follows:

Pretreatment system: Remove impurities and suspended matter in raw water, protect the reverse osmosis membrane from contamination and blockage.
First stage reverse osmosis system: operating under high pressure, remove most of the salt, organic matter and microorganisms in the water, so that the water quality is initially purified.
Secondary reverse osmosis system: further remove impurities and organic matter in the primary reverse osmosis production water to produce high-purity water.
Post-treatment system: Sterilize the produced pure water and adjust the pH value to meet different water needs.
