About 200 enterprises producing meat product and more than 50 of the dairy industry operate in Republic Belarus. Up to 70 % water used these industries is contaminated with fatty substances. At present, physicochemical methods (coagulation flocculation) biological treatment using microorganisms-destructors fats oils are most widely for fat-containing wastewater, it advisable use combination. Re...

The milk processing industry is one of the world's staple industries, thus the treatment possibilities of dairy effluents have been attracting more and more attention. The purpose of the paper is to review contemporary research on dairy wastewater. The origin, categories, as well as liquid by-products and general indicators of real dairy wastewater are described. Different procedures applied fo...

This paper considers control structure selection for a biological wastewater treatment process, with emphasis on identifying controlled variables that contribute to minimize economic costs. This is achieved according to the selfoptimizing procedure proposed by Skogestad (2000). The aim is to demonstrate how, with simple considerations on the control structure design, the efficiency of a wastewa...

Purpose. The main purpose of the article is to develop a 3D CFD model for modeling process biological wastewater treatment in an aeration tank. Methodology. For mathematical reactor, taking into account flow hydrodynamics, geometric shape tank, convective-diffusion transfer substrate and activated sludge, was built. based on three-dimensional equation motion ideal liquid mass conservation subst...

Existing wastewater treatment plants (WWTPs) face huge challenges that can impede the achievement of sustainable development goals for clean water and sanitation (SDG 6) energy 7), amongst others [...]
