The biochemical processes occurring in sand filters loads of tertiary treatment of urban wastewater are investigated. The significance of those processes in reducing the overall biochemical and chemical oxygen demand in water purified by filters was established. The studies were conducted in natural conditions of the wastewater treatment plant in Krasnoyarsk using the installation for filters’ technological modeling. Equations for calculating and adjusting filtering parameters, taking into account biochemical processes, were obtained.
