ULP series (ultra low pressure) aromatic polyamide RO element is developed by X 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%-99.7%. 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.

Advantages
1. Reverse osmosis membranes have a highly efficient desalination rate;
2. Reverse osmosis membranes have high mechanical strength and service life;
3. Reverse osmosis membranes can function at low operating pressures;
4. Reverse osmosis membranes are resistant to chemical or biochemical effects.
Applications
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.
