HR Series Spiral-wound Membrane is the composite membrane that specially developed for the desalination and purification of brackish water, and the main features include:

Ø Low power consumption, low operating pressure;
Ø High desalination rate;
Ø High filth allowance, high anti-pollution and stable operation;
Ø High porosity, high water producing and high quality of water production.

Main application: desalination of brackish water, producing pure water or ultrapure water, boiler feed water in plant and industrial water. Or high concentration of brackish water with salts.

 

 

Table 1: Parameter of Membrane Element

 

Product Model	Average Flow Rate GPD(m3/d)	Average Retention Rate
HR-RO15-4040	2700(10.2)	99.5%
HR-RO15-8040	11500(43.5)	99.5%

 

·  After operating for 24 hours, measure the average rate of desalination. Fluctuation range of flow for a single membrane element is +25%/-25%.

·  Measure Condition : NaCl solution of 2,000 ppm, 225psi of operating pressure, 25℃ of temperature, pH7and 15% of recovery rate.
