Due to the severe pollution taken place in Taihu Lake, the investigation of water source quality in Taihu Lake is urgent for the development of drinking water treatment processes. Water samples taken from two water source areas in Taihu Lake were analyzed. The results showed that ammonia, TN, TP and CODMn were the dominant contaminants. The concentrations of those contaminants all exceeded “surface...
This article describes a pulsed arc electrohydraulic discharge reactor for the treatment of contaminated pond-water and a detailed study of fundamental characteristics, including plasma parameters, pressure wave propagation, optical emission spectrum and the decay time of the radicals is discussed.
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...
Endocrine Disruptors, which is trace but more and more noted in aquatic environment, has a significant effect on people's hormone systems. The estradiol (E2) was a research object, and the effects of solution parameters (concentration, pH, ionic strength and natural organic matter (NOM) ) on the retention of trace E2 by nanofiltration membrane (NF) (BDXN-90 polyamind aromatic compound membrane) filtration...
Since humic acid from water causes considerable serious health-risk factors, powerful methods for the removal of those have received increasing attention over the past decade. In this paper, the available technologies for removal of humic acid from water are briefly reviewed, and the recent advancements are summarized. Fundamentals and main applications of typical methods such as filtration, flocculation...
Ammonia addition and pH depression can inhibit the formation of bromate in ozonated drinking water by reacting with free bromine (HOBr/OBr-), an intermediate in bromate formation, to form bromamines and other bromoorganic disinfection byproducts. This study was performed to assess the effects of ammonia and pH value combinations on the formation of bromate and THMs during ozonation and chlorination...
