Bol'shakova O. System for Audit and Regulation of Industrial Effluent Discharges into the Municipal Sewer System and Surface Water Bodies. - Manuscript.

Dissertation paper of O.S. Bolshakova is dedicated to resolving the issues relating to minimization of adverse impacts of industrial effluents on operation of the municipal sewer systems, wastewater treatment facilities, properties and composition of wastewater sludge generated in the process of wastewater treatment, and state and quality of surface water bodies. A special algorithm and computer software has been developed for calculation of individual parameters describing the quality of industrial (leather tannery) effluents discharged into the municipal sewer system. On the basis of a special survey, an algorithm for calculation of the required capacities/concentration to be achieved at industrial effluents settlement/clarification ponds. Proposed are new technical solutions on reducing the quantity of industrial effluents discharged into the municipal sewer systems by machine building industries. It is noted that introduction of individual (industry-specific) industrial effluents requirements allows to improve the operations of the municipal sewer systems, wastewater treatment facility operation efficiency, and to reduce pollution of surface water bodies with industrial effluents.
