Nanofiltration Membranes Introduce
The industrial nano filtration element is designed for removing from water various
organics,microbes,viruses and most metallic ions with two or higher valence while
retaining part of the sodium,potassium,calcium and magnesium ions,etc.
Nano filtration,free of chemical reaction,heating and transformation, can keep the
biological activity undamaged and maintain the primary flavor or fragrance of substance
unchanged, and is increasingly applied in production of drinking water and in separation
and concentration/purification processes for foodstuff,medicine,biological engineering
and pollution treatment,etc.
VNF1 : Moderate rejection rate; Moderate passage of calcium; High removal of TOC
VNF2 : Higher rejection rate; Satisfactory removal of insecticide, herbicide, TOC
