German Pumps for Algerian Sewage Plants

When completed, German pump technology from Allweiler AG will help treat wastewater in the four new Algerian sewage plants. This includes a large plant in Oran, capital of the Algerian province of the same name and the second-largest city in the country with 1.5-million residents.

Working closely with the Austrian plant builder VA Tech Wabag, Allweiler planned and configured this major project in addition to three other plants. These projects required a total of 48 progressing cavity pumps and macerators that are adapted and utilized according to the prevailing requirements. Nine pumps of the AEB series and twenty-five Tecflow pumps are used in the preliminary stages of the treatment process to move untreated wastewater. In the final stage of wastewater treatment, four AE-RG pumps transport drained sludges that may have a dry substance content as high as 45%. Additionally, four ANP-series pumps are used to meter process-optimization polymers. Two of the AE-RG pumps are unique in that they are four-stage units designed for a very high maximum differential pressure of 15bar.

Allweiler's Austrian and French sales partners remained engaged with the plant builder throughout the entire project - starting with the proposal and continuing with dimensioning, advisory services, delivery, and installation.
