The Application Scope
1. KeenSen BW series is mainly used to the treatment of brackish water.The standard operating pressure is 1.55MPa. In actual project application, the operating pressure is affected by the concentration of water quality, system recovery rate, etc.
2. The FR series is mainly applied to the treatment and reuse of surface water, industrial wastewater, and the salt rejection of moderate-high brackish water. FR Series are greatly increased the resistance of the dirt plugging of system and reduce the cleaning frequency, etc. The standard operating pressure is 1.55MPa. In actual project application, the operating pressure is affected by the concentration of water quality, system recovery rate, etc.
Product Advantage
The BW Series is stable in performance with wide application range, high salt rejection rate, high flux, extended service life, can save the equipment investment and operating expense.
