A Study of Dual Polymer Conditioning of Aluminium-based Drinking Water Treatment Residual
نویسندگان
چکیده
Conditioning of an alum-based water treatment sludge by single and dual polymers was investigated in this study. Capillary suction time (CST), specific resistance to filtration (SRF) and settling rate of conditioned sludge were used to evaluate the sludge dewatering characteristics. Sludge dewaterability resulting from single and dual polymer conditioning were compared for the purpose of exploring the validity and effectiveness of dual polymer conditioning strategy. Unlike activated sludge derived from wastewater treatment, results from this study have demonstrated that conditioning of the alum sludge by the combined use of an cationic polymer (FO-4140) followed by

متن کاملThe application of Polyaluminium Ferric Chloride for Turbidity and Color Removal from Low to Medium Turbid Water
Background & Aims of the Study: Coagulation is an essential process for the removal of fine particulate matter in water treatment. Polyaluminium ferric chloride (PAFC) is a composite inorganic polymer of Aluminium and ferric salt. This study was conducted to find out the optimum coagulation conditions for the removal of turbidity, color and organic matter (UV absorbance) in low to mediu...
متن کاملOptimizing the coagulation process in a drinking water treatment plant -- comparison between traditional and statistical experimental design jar tests.
In this study of coagulation operation, a comparison was made between the optimum jar test values for pH, coagulant and coagulant aid obtained from traditional methods (an adjusted one-factor-at-a-time (OFAT) method) and with central composite design (the standard design of response surface methodology (RSM)). Alum (coagulant) and polymer (coagulant aid) were used to treat a water source with v...
متن کاملDrinking water quality monitoring using trend analysis.
One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled measure...
متن کاملHeterotrophic Bacteria Count Index in Drinking Water and Possibility of Biofilm Formation in Household Drinking Water Treatment Devices in Sari, Iran
Background and purpose: Household drinking water treatment devices are becoming commonplace to improve the quality of drinking water, remove odor, taste, turbidity and color, pathogenic organisms, toxic chemicals, organic matter, and carcinogenic pollutants. This study aimed at investigating the Heterotrophic plate count (HPC) in drinking water and possibility of biofilm formation in household...
