Brief Introduction:
ULP series (ultra low pressure) aromatic polyamide RO element is developed for treatment of surface water and underground water. its operation pressure is about 2/3 of low pressure membrane, and the rejection rate can reach 99.5%. Thus it can reduce the investment cost of related pumps, pipelines, containers and other equipments and the operation cost of RO system, improve economic benefits.
Scope of Application:
ULP series RO element normally suitable for treatment of surface water, underground water and municipal water with TDS is less than 2000 ppm. It is mainly applied in bottle water, drinking water, boiler replenishment water,food processing and pharmaceutical manufacturing industries and other fields.
