Optimisation of reaction conditions of particle aggregation in water purification – back to basics
AbstractBasic types of pollutants in surface waters and methods for their removal are reviewed. Guidelines are provided for selecting the most effective hydrolysing destabilisation reagent (coagulant) for a particular quality surface water, which is polluted with different types of impurities, and optimising the reaction conditions under which its purification takes place.
Key words: mineral impurities, natural organic matter (NOM), natural biological materials (NBM), aggregation stability, aggregation destabilisation, optimum dosage, optimised reaction conditions, optimised dosage and optimised reaction pH
