A method for calculating the volume of an intermediate storage tank in storm sewer systems for management and treatment

Abstract

The purpose of the article is to clarify and supplement the methodology given in the current regulatory and methodological framework for the purpose of engineering calculation of the storm flow management scheme for sewage treatment plants. The flow control scheme, including an intermediate tank, a pumping station and a separation chamber, is analyzed by mathematical modeling using a computer algebra system. Changes are proposed in the calculation formula for determining the volume of storage tank for the scheme of emptying the tank by pumps, taking into account all types of separation chambers. The dependence is established and graphs are shown showing the effect on the volume of the tank of the coefficient, which takes into account the variability of the flow diverted by the separation chamber into the collector.

Optimal volume of flow tanks for rainwater management

“…Surface, including rain and snowmelt, untreated wastewater causes serious environmental and health problems, being the main source of pollution and a huge mass of waste that is washed away from the territory of industrial facilities and residential buildings. This ultimately destroys the environment and endangers the ecological safety of the population [1][2][3]. Underground pipeline systems and treatment plants, usually of a storage type, are used for the orderly collection, disposal, and purification of wastewater from pollution [4][5][6].…”
