An increase in the share of sanitary towels and wipes and a smaller share of water ensure a significant change of the composition of wastewater, which leads to massive clogging of the pumps of wastewater treatment plants. Subsequently, the financial expenditures for cleaning, servicing and repair for wastewater companies have increased enormously in recent years.
In order to solve this problem sustainably, the German Institute for Energy and Environmental Process Technology at the Duisburg-Essen University, on behalf of the Pleiger Maschinenbau GmbH & Co. KG, carried out a fluid mechanics investigation on the clogging behaviour of single vane impellor pumps. From this research work an optimised impeller geometry has been developed for wastewater pumps. It provides a significant improvement of the flow with regard to susceptibility to clogging in the inlet area of the impeller and thus for a strikingly increased operating safety with appreciably lower servicing costs.
The new, optimised impeller geometry reliably prevents costly clogging in pump stations. As from the very beginning it was systematically developed also for the possibility of inexpensive retrofitting of existing pumping plants, it is suitable not only for employment in new developments.
