Irrigation and Melioration

Abstract

Reliability of the pumping station equipments mainly depend on the purity and level of water, flowing to the pump station. Equipments of big pumping stations fail mainly due to mechanical effects of different materials (debris) like trunks, roots of tree and canes. The article presents the results of studies which were conducted to determine the amount, composition and size of the floating debris, and also suggested modernized equipment for cleaning trash racks mounted in front forebays. There are given results of how to determine parameters of the e quipment for cleaning trash racks.
