The Influence of Waste Water Composition on the Pumping System Corrosion

Abstract

Wastewater piping systems in urban agglomerations or industrial areas have problems with the wear and tear of equipment and water transport pipelines used. The problems are related to hydromechanics wear and corrosion due to the presence of solid particles transported with water and due to the residual chemical compounds resulting from industrial technological processes, as well as the presence of biological waste from domestic consumers. In the paper are presented the corrosive characteristics of the waste waters and a review of the effects of wear and corrosion in the case of submersible pumps is made.
