DOMESTIC & COMMERCIAL MEMBRANE ELEMENTS
JK Domestic & Commercial series can all-around remove the organics, microorganism, virus, metal ion, active particles and cancerogenic substance and mainly applied in drinking fountain in house, office and business area.
JK nanofiltration (NF) and (EC) series can retain Na+,K+,Ca2+ and Mg2+ which can maintain content of mineral and nutrient substance while remove harmful substance in water. The advantages of low operation pressure and high flow break with tradition that drinking fountain must be supported with pump or water storage tank. By lower cost and smaller area, the NF and EC series brings new age of drinking fountain.
