Single stage reverse osmosis equipment is mainly used for users with good water quality or low water quality requirements; Double stage reverse osmosis equipment is mainly used for users with poor water quality or high water quality requirements.

The desalination rate of single-stage and two-stage reverse osmosis equipment is different, and the desalination rate of two-stage reverse osmosis equipment is higher than that of single-stage reverse osmosis equipment.

Single stage reverse osmosis equipment, also known as first stage reverse osmosis equipment, refers to the process where the raw water is directly transported to the reverse osmosis device through a pre-treatment system and precision filter, and then through a high-pressure pump. It is called single stage reverse osmosis.

Double stage reverse osmosis equipment, also known as two-stage reverse osmosis. After being pressurized, the raw water is sent to the pre-treatment system for coarse filtration, and then filtered through a fine filter before being pumped to the first stage reverse osmosis system by a high-pressure pump. The water generated by the system is pressurized by a two-stage high-pressure pump and enters the secondary reverse osmosis system to produce product water, which is called secondary reverse osmosis.

Double stage reverse osmosis, also known as secondary reverse osmosis pretreatment system, raw water pump, multimedia filtration storage system, liquid level controller, and water tank.

Double stage reverse osmosis is the process of adjusting the pH value to allow water to permeate through the first stage of reverse osmosis, and then being pumped to the second stage of the reverse osmosis system by a high-pressure pump.

The desalination rate of a single-stage reverse osmosis system is relatively high. In this way, raw water with a salt content less than 1000ppm can be directly treated without ion exchange, and the water quality meets the third level water quality standard of GB6682-2008 in the laboratory.

The main configuration of two-stage reverse osmosis is as follows:

Pre treatment system: raw water pump, multimedia filter, activated carbon filter, automatic softener, pipeline, valve

DRO reverse osmosis system: primary high-pressure pump, secondary high-pressure pump, reverse osmosis membrane, reverse osmosis membrane shell, membrane frame, control system inlet, solenoid valve, flushing solenoid valve, pressure regulating valve, high-pressure switch, low-pressure switch, precision filter, pipeline, valve.
