Abstract

The object of the study is wastewater generated during the salting of fish, containing suspended solids, phosphates, chlorides, organic contaminants, etc., as well as wastewater generated after washing the equipment used in the production and process tanks. Waste water, in accordance with the established requirements, is treated with chemical reagents, where the coagulant of the KEMIRA PAX 20 series (a solution of aluminum polyoxychloride based on Al3+) is used as a coagulant. The purpose of the work: for more economical use of aluminum polyoxychloride, based on stoichiometric calculations of reaction equations, select the optimal dose of coagulant necessary to intensify the processes of flocculation, taking into account the pH of the waste water, determine the alkali consumption and the conditions for its dosing into the treated water.
