Coagulation of waste water from the point of view of physic-chemical interactions

The widespread use of reagent coagulation in the technology purification natural and waste waters is due to complexity chemical composition phase-dispersed state aqua systems these waters, on one hand, multifactorial action coagulants them, other. mechanisms interaction between pollutants wastewater which are different states include physicochemical phenomena coagulation, heterocoagulation, adagulation sorption. concept “coagulation” reflects only mechanism coagulants’ pollutants. This leads appearing problem terminological description processes’ combined when adding water being cleaned. purpose study justify universal indicators characterizing nature process, its formalization quantitative assessment. solution “coasorption”, determines pollutants, technological indicator “specific coasorption”, establishes a relationship pollutants’ dose coagulant. test coagulation’s results two types synthetic dyes’ solutions using aluminum salts reflect difference their with formula for coasorption isotherm can be used determine required doses reagents basing initial residual content purified waters.
