Abstract

Abstract:

The main micro-pollutants in tap water in the Pear River Delta area are organic matter, disinfection by-products, NH₃-N and nitrite.A deep treatment test to this type of tap water was designed and conducted by the combination technique of nanofiltration and other filtrations. The results show that this technique can remove about 90 % of the organic pollutants, and the purified water can reach very high standard.

Key words: nanofiltration, deep treatment for drinking water, tap water, pollutant

CLC Number:

TQ085.411
