Dual stage reverse osmosis
Raw water (tap water, surface water, groundwater) is pressurized and sent to the pre-treatment system for coarse filtration. After entering the precision filter for filtration, it is pressurized by a first stage high-pressure pump and sent to the first stage reverse osmosis system. The water produced by this system is then pressurized by a second stage high-pressure pump and sent to the second stage reverse osmosis system to produce product water, which is called two-stage reverse osmosis.
Double stage reverse osmosis, suitable for water with conductivity greater than 500us/cm, with effluent conductivity ranging from 1-10 us/cm
