Wastewater and Sludge Treatment

NEMO® BP progressing cavity pump with abp-module® prevents system downtime

Rotating positive-displacement pumps have been used for decades in wastewater and sludge treatment as handling systems for all types of substances. Due to their regulatory properties, these pumps deliver secure, dependable, and efficient processing.

Along with sand additives, wastewater being treated often contains coarse floating pollutants, decomposing matter, sludge-generating particulate materials, dissolved organic matter and bacteria.

None of these substances present any problem for NETZSCH Pumps and Grinding Systems: Our NEMO® Progressing Cavity Pumps and NETZSCH TORNADO® Rotary Lobe Pumps, along with the NEMO® M-Ovas® provide you with the optimal technical solution for your application.

The following flow chart shows the individual processing steps in wastewater treatment for communal and industrial sewage plants, from inflow to discharge into the disposal system, along with the corresponding sludge treatment.
