secondary reverse osmosis

1. two-stage reverse osmosis:
the raw water (tap water, surface water, groundwater) is pressurized and sent to the pretreatment system for coarse filtration, and then filtered through the precision filter, and then sent to the first-stage reverse osmosis system through a high-pressure pump. the two-stage high-pressure pump is pressurized and sent to the two-stage reverse osmosis system to produce product water, which is called two-stage reverse osmosis.

2. process flow chart:

two-stage reverse osmosis is suitable for water with conductivity greater than 500μs/cm, and the conductivity of the effluent is 1-10μs/cm.
