The difference between bipolar reverse osmosis and single-stage reverse osmosis equipment

Single stage reverse osmosis, also known as primary reverse osmosis equipment, refers to the process where the raw water passes through a pre-treatment system and precision filter, and is directly delivered to the reverse osmosis device through a high-pressure pump to produce product water.

Double stage reverse osmosis, also known as second stage reverse osmosis, pressurizes the raw water and sends it to the pre-treatment system for coarse filtration. After entering the precision filter for filtration, it is pressurized and sent to the first stage reverse osmosis system through the first stage high-pressure pump. The water produced by the system is then pressurized by the second stage high-pressure pump and sent to the second stage reverse osmosis system to produce product water, which is called double stage reverse osmosis.

The difference between unipolar reverse osmosis equipment and two-stage reverse osmosis equipment

1. The difference in appearance between single stage reverse osmosis equipment and bipolar reverse osmosis equipment is that a single stage reverse osmosis equipment is equipped with a vertical pump, while bipolar reverse osmosis equipment is equipped with two vertical pumps.

2. In terms of system differences, single stage reverse osmosis equipment is a device that removes some substances from water through a single penetration membrane separation technology. Bipolar reverse osmosis equipment refers to the filtration of raw water through two R0 reverse osmosis membranes to achieve a higher desalination rate standard. When the water quality of the raw water is close to that of tap water, the secondary reverse osmosis technology can achieve a conductivity value of 10 μ When industries such as S/CMO do not have high requirements for water quality, single stage reverse osmosis equipment will be used. If there are strict requirements for water quality, double stage reverse osmosis equipment will be used.

The single stage and double stage of reverse osmosis equipment are mainly distinguished from the process flow.

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