Ranking of coagulants for wastewater treatment using partial order theory digital Ranking of coagulants for wastewater treatment using partial order theory
Year: 2011
Jar-test is a useful tool for chemicals selection for physical–chemical wastewater treatment. The results show the treatment efficiency in terms of suspended matter and organic matter removal. However, in spite of having all these results, coagulant selection is not an easy task because one coagulant can remove efficiently the suspended solids but at the same time increase the conductivity. In this paper, the use of Partial Order Scaling Analysis (POSA) is proposed to help on the selection of the coagulant and its concentration in a sequencing batch reactor (SBR). An evaluation of two commonly used coagulation-flocculation aids was conducted and based on jar tests and POSA model, Ferric Chloride (100 ppm) was the best choice. Keywords: Coagulation, Jar Test, Partial Order Scaling Analysis, Treatment Selection.
