Low Pressure RO Element

KEYA Low Pressure RO Element is developed for treatment of brackish water.It has the characteristics of low-pressure in operation, high permeate flow and excellent rejection performance in removing of solvable salts, TOC, SiO2, etc.It is especially suitable for the preparation of high purity water in electronics and power industry.

SKU: N/A Category:

Low Pressure RO Element is normally suitable for treatment of brackish water, surface water, underground water and municipal water with TDS is less than 10000ppm.It is mainly used for producing various scales of bottle water, drinking water, industrial used pure water, high purity water, boiler replenishment water, also for waste water reuse, material concentration, purification and refining purposes.
