Extra low pressure RO membrane element
Category:
Product features
1、Suitable for treatment of surface water,groundwater,tap water, municipal waterand other water sources, with water TDSbelow 1000 ppm.
2、Under extremely low operating pressure.high rejection and high flow can beobtained, thus the operation cost of relevantpumps, pipelines, containers and otherequipment,are reduced.
3、It is widely used in bottled water, direct drinking water, boiler make-up water,food processing and pharmaceutical manufacturing industries with low operation cost and high water quality.
