Title

USING COAGULATION PROCESS IN OPTIMIZING NATURAL ORGANIC MATTER REMOVAL FROM LOW TURBIDITY WATERS

Pages

  2-7

Abstract

 Optimization of COAGULATION process for efficient removal of Natural Organic Matters (NOM) has gained a lot of focus over the last years to meet the requirements of enhanced COAGULATION. NOM comprises both particulate and soluble components which the latter usually comprises the main portion. Removal of soluble NOM from low turbidity waters by COAGULATION is not a successful process unless enough attention is paid to stages of formation and development of both micro and macro-floes. This study, which presents experimental results from pilot scale research studies aimed at optimizing COAGULATION process applied to synthetic raw waters supplemented by adding commercial humic acid with Low turbidity levels, explains how pH and turbidity can be controlled to maximize soluble NOM removal. The removal of NOM at various coagulant doses and COAGULATION pHs has been assessed through raw and treated (coagulated-settled) water measurements of total organic carbon (TOC). For low turbidity waters, essential floc NUCLEATION sites can be provided by creating synthetic turbidities, for example by adding clay. Adjusting the initial pH at 5.5 or adding clay before coagulant addition allows the formation of micro-floes as well as formation of the insoluble flocs at low coagulant doses.
