Behavior of organic polymers in drinking water purification Author: Lee JF (REPRINT) ; Liao PM; Tseng DH; Wen PT Journal: CHEMOSPHERE , 1998 , V 37 , N6 ( SEP ) , P 1045-1061 Abstract: Synthetic organic polymers used to purify drinking water are severely limited in that their impurities and byproducts harm human health. In this study, the undesired effects resulted from chlorination and the enhanced attenuation of toxic organic compounds in drinking water from using synthetic organic polymer coagulants were investigated. In the simulated drinking water purification processes, synthetic organic polymers were used as coagulant aids, reacted with a disinfectant(chlorine) and formed a large number of volatile organic compounds (VOCs). Chloroform and benzene which, are carcinogenic compounds, had the maximum formation potential. Experimental results indicated that the total formation potential of these disinfection by-products significantly increased in the presence of turbidity. On the other hand, adding organic polymers to the coagulation systems resulted in more extensive remove of toxic organic compounds and turbidity. In coagulation and flocculation processes, the formation of clay/polymer complexes can facilitate the removal of toxic organic compounds in contaminated water. 2.

Survey result of the treatment function of Shimizu River water purification facilities. Tochigiken Kogai Kenkyujo Nenpo , 1994 , NO.18 , PAGE.27-32 , FIG.5, TBL.2, REF.3 Abstract: Uzuma River flowing in the urban area of Tochigi City shows considerable water pollution. Tochigi City installed a direct river purification facilities by Shimizu River, one of the inflow tributaries of Uzuba River in the fiscal year 1990 for the purpose of purifying the river water. In the fiscal years 1990 and 1991, the fundamental treatment function of the facilities was examined and, in the fiscal year 1992, the treatment function of the facilities with the charcoal treatment appended for attempting the improvement of the purification function was examined and, in the fiscal year 1993, the rise of extraction rate of the water pollutant, after conversion of the charcoal treatment to a catalytic oxidation tank in which a coagulant was added, was examined. By the addition of polymer coagulant ( polyacrylate ) of about 5mg/l, extraction rates of SS, BOD, T-N and T-P were improved in the range of 6-34%. 4.
