Rotating positive-displacement pumps have been used for decades in the treatment of wastewater and sludge as conveying systems for all types of media. Due to their regulatory properties, these pumps guarantee secure, dependable, and efficient processing.
Besides sand additives, wastewater being treated often contains coarse floating pollutants, decomposing matter, sludge-generating particulate materials, dissolved organic matter and bacteria.
None of these media present any problem for NETZSCH Pumps and Grinding Systems: Our NEMO® Progressing Cavity Pumps and NETZSCH TORNADO® Rotary Lobe Pumps, along with our NEMO® M-Ovas® and NEMO® Twin Shaft Macerator grinding systems, provide you with the optimal technical solution for your application.
