Trihalomethanes in drinking water reduction through air stripping

The laboratory-scale and pilot-scale experiments were conducted to investigate the efficiency of controlling trihalomethanes(THMs) yields by combined preoxidation,which was carried out by potassium permanganate composite(PPC) and chlorine using a typical contaminated resource water in northern China.

Variations of assimilable organic carbon(AOC),trihalomethanes(THMs) and haloacetic acids(HAAs) in two different water distribution systems(DSs) were investigated in Shanghai,a eastern city of China.

Combined pretreatment of potassium permanganate and chloramines to control trihalomethane formation;

7% of total organic carbon and produce more trihalomethane than other fractions in the raw water.

The decrease of total haloacetic acid and trihalomethane is about 69.

Determination and Evaluation of THMs in Water Supply in Kelamayi City

Some organic matter that have aromatic structure similar as humic acid are selected to conduct chlorination test,determined the formation of HAAs & THMs of tested matters,researched the relationship of the chemical structure of DBPFP with DBPs formation characteristics.
