Distribution and Transformation of Molecular Weight of Organic Matters in a Canal Water Treatment Procedure

Article Preview

Abstract:

Distribution and transformation of molecular weight of organic matters in canal raw water, primary coagulated water, secondary coagulated water, enhanced coagulated water and water filtered by activated carbon were monitored by ultrafiltration membrane method. The results show that organics on the fraction of molecular weight less than 2kDa has the largest ratio in total organics of outlets of coagulation and activated carbon tank. Removal rate of total organics is about 73% by secondary coagulation, but which of micromolecule organics of molecular weight less than 2kDa is only 10%, which can be removed by activated carbon more than 80%.
