Conventional drinking water treatment plant consists of coagulation, flocculation, sedimentation, and filtration and disinfection units. Depending on water quality influent, each unit can be optimized to achieve the desired water quality effluent, both in design and operation stages. A typical water treatment plant has the combination of processes needed to treat the contaminants in the source water...
Laboratory experimental studies were carried out on river water, reservoir water and enriched natural organic mater (NOM) to evaluate the effect of Br- brought about by seawater intrusion on the formation of trihalomethane (THM). The experimental results indicated that the quality of river raw water and reservoir water collected was good with a TOC of less than 2.5 mg/L and a maximum THM formation...
In this paper, the effect of coagulation on membrane filtration resistance had been studied in the process of membrane filtration with dosing coagulants, analyzed the contribution of different membrane resistance in the membrane process, in order to find an effective way to control the membrane resistance. By Carman-Kozeny formula analyzed, voidage and deposited particle size of the composite cake...
A combined O3/BAC (biological activated carbon) process for the removal of DBP(disinfection by-product) precursors from drinking water and maintenance of biological stability in distribution system is being investigated. The objective of this study is to evaluate removal of THMFP and AOC (assimilable organic carbon) during long term operation of an O3/BAC process. A pilot scale experiment for drinking...
