INTRODUCTION
BOKA Water ULP aromatic polyamide composite membrane elements are specially developed for groundwater and surface water treatment applications. Operating at approximately two-thirds of the pressure required by conventional low-pressure brackish water membranes, they help reduce energy consumption while delivering a salt rejection rate of up to 99.5%. With excellent desalination performance, the membranes can maintain the required permeate flow even under very low operating pressure conditions.
It mainly applies to treatment for surface water, groundwater, municipal water, etc. within salinity<2000mg/L. The application fields include bottled drinking water, dual water supply in residential area or industrial park, food and beverage production, etc. It has the characteristics of higher permeate flow, low operating pressure as well as high rejection rate.
