From wastewater to sludge treatment Egger is present in many areas of wastewater treatment from pumping raw sewage, sand and water mixtures, primary sludge, recirculation, recycled and digested sludge to other secondary sludge such as lime water and activated carbon suspensions. The liquids involved in these processes may be strongly abrasive or corrosive, or they may be multi-phase mixtures with a high gas content. As a specialist in pumping fluids containing solid matter and gas, we accept any challenge. Our Iris® diaphragm control valves also offer the perfect solution for precise...

High discharge heads Closures of smaller wastewater plants mean that transition pump plants have to cover long distances and overcome large differences in height. In the case of raw sewage, with indi­ idually operating Egger Turo® vortex pumps, discharge v heads of up to 90 m are possible. When these pumps are operated in series, discharge heads of up to 150 m can be achieved. Not all centrifugal pumps can achieve such discharge heads at speeds of 1,450–1,750 l/min. This technology combines characteristics such as reliable pumping of raw sewage with low wear and tear at lower speeds. In...

Flow control of process air / sludge In wastewater treatment plants after the activated sludge process, approx. 60 % of the total energy requirement is needed to transfer atmospheric oxygen into the biological process. There is considerable potential here for many plants to save energy. Efficient control of air volumes Over recent years, the Iris® diaphragm control valve has been tried and tested in hundreds of wastewater treatment plants where it is primarily used to effi­ ciently control air volumes in activated sludge tanks. Through its unique design with a continuously variable cross...

Sludge treatment Sludge handling plays a central role in wastewater treatment and also poses particular challenges regarding technology and energy consumption. Egger possesses many years of ex­ perience in this stage of treatment, for example in the following areas: ·· drawing off primary sludge during the primary treatment process ·· conveying sludge across long distances ·· sludge circulation in digestion towers ·· coating digestion towers. Trouble free operation thanks to the right hydraulics The well-proven Turo® vortex pump is used for small to averagesized volumes whereas EOS series...

Our products, our expertise Each Egger pump is unique, custom-tailored and assembled on a modular basis or even designed individually and in our many years of practice, we have gained extensive experience with the most varied media. Our pump experts will be pleased to advise you on cost-effective solutions for your applications. Turo® vortex pumps T This range offers a completely open spherical channel as a result of the recessed impeller, with only 15% of the pumped medium coming into contact with the impeller. Turo® pumps are therefore used, vice-versa, for gentle pumping of sludge of all...
