Specific features of retrofitting mechanical wastewater treatment
at sewage pumping stations

Summary

The process solutions applied at most of the sewage pumping stations built in the second half of the last century became obsolete, and the equipment installed in screen chambers was not designed to handle the current volumes and composition of wastes. Today, fibrous inclusions present in wastewater in large amounts pose certain difficulties in the operation of equipment. While upgrading the facilities, it is important to take into account the requirements of reliable and economical operation of the equipment in screen chambers, and significant differences in the conditions of its operation compared to the operation of similar equipment at the wastewater treatment facilities. The examples of the process solutions implemented by MY PROJECT JSC on the basis of the equipment designed by Ecopolymer TPE are presented. Comprehensive solutions have been proposed for pumping stations with the inlet manifold of various depth, including screens, as well as the equipment for grinding, transporting, dewatering and removing the screenings. The implementation of process solutions provides for maintenance personnel downsizing and reducing operating costs in general.
