Rainwater/general-flow chambers

Mathematical modeling using FLOW-3D


3D modeling provides an opportunity to confirm the correctness of the adopted design solutions for the connection chambers, allows to optimize the shape of baffles and overflows, kinetas, as well as medium supply and discharge. It allows you to determine the lengths of overflow edges and the diameters of backflow flaps in relation to the values of flows in channels and operating conditions in order not to exceed the critical value of the ordinate of pressures on overflows in individual chambers. Allows to locate areas of deposition of lifted debris and pollutants. Provides an opportunity to optimize the shape due to the oxygenation of the medium.

The reinforced concrete chamber provides an opportunity to securely connect the general wastewater supply pipeline after separation with the through pipeline. The wastewater is directed to the pumping station and further to the treatment plant. The chamber has overflow windows. The main working overflow is located in the wall separating the chamber space into two parts. In the first there is an open pipeline that carries the general sewage and rainwater inflow. In the second part there is a wall with a backwater flap, separating the backflow from the receiver at high levels.


The process of mixing the rainwater effluent and the conducted combined sewage causes the concentration of the sample analyzed pollutant indicator to change both in the pipeline conducting the effluent and discharging the excess into the receiving body. 

The process of mixing rainwater effluent and conducted combined sewage causes the concentration of the sample analyzed fraction to change both in the pipeline leading the effluent and discharging the excess.

The process of mixing the rainwater effluent and the conducted combined sewage causes the aeration rate to change in both the effluent leading and the effluent discharging pipelines.
