Peak fitting and modelling of NOM removal by coagulation from River Murray water in South Australia

Abstract

Removal of natural organic matter (NOM) remains a major challenge confronting the water industry in Australia, in the supply of safe drinking water. Its treatability can vary depending on its character and this may be enhanced by optimising the inorganic coagulant dose and depending on the coagulant type, the coagulation pH. Generally, in coagulation modelling input parameter like pH, UV abs 254nm, turbidity and colour have been used in modelling approaches. However UV abs 254nm and colour does not comprehensively describe the character of NOM and improved characterization techniques should lead to better assessment of treatability of water by conventional treatment process.
