Two grade RO system

Two Grade Reverse Osmosis system composes of the pre-treatment system, double RO membrane modular system, the C.I.P. station, and the post treatment, The system is suitable for producing higher level of treated water with TDS range from 5ppm to 10ppm, normally will be used for industrial ultra-pure water treatment, coming along with a lower water recovery.


Two Grage RO system means that the water goes through the first RO modular system which is composes of one set of centrifugual high pressure pump and one RO membrane modular system, then the treated water will be put into a buffering water tank to be treated through the second RO modular system, a second centrifugual highpressure pump will be equiped for the two grade RO system.
