Wastewater and Sludge Treatment

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.

Products

TORNADO® Industrial Rotary Lobe Pumps T2

NETZSCH TORNADO® industrial rotary lobe pumps are versatile stand-alone equipment. Used primarily in environmental technology and the chemical industry, these pumps handle almost any substance continuously and gently while metering in proportion to rotation speed.

NEMO® BP Open Throat Progressing Cavity Pump with Auger and Bridge Breaking Paddle or with aBP-Module

For highly viscous, compacted and crumbly substances that have a tendency to bridge, the NEMO® BP Progressing Cavity Pump is the optimal solution. The NEMO® BP can be used in nearly all industrial markets to provide continuous, pressure-stable, gentle and low-pulsation handling with metering in proportion to rotation speed.

The NETZSCH TORNADO® Mobile

A TORNADO® rotary lobe pump fastened onto a mobile base – this is the NETZSCH TORNADO® Mobile. The concept of mounting the equipment onto a car or truck trailer makes it possible to pump large quantities of fluids with solid content, wastewater and slurries at the most unusual of sites.

NEMO® BY

NEMO® BY Progressing Cavity Pumps can be used in industrial markets where a great variety of substances must be pumped or very precisely metered.

M-Ovas® Grinding System

NETZSCH M-Ovas® grinding systems can be used wherever it is essential that solid matter in fluids be broken down reliably to ensure the prevention of pipe clogging and damage to downstream equipment.

NEMO® SY Industrial Construction in Bearing Housing Design with Free Shaft Extension

The NEMO® SY Progressing Cavity Pump is used for demanding applications in every branch of industry worldwide. Bearing block with free shaft extension design pump can be run with any type of drive, such as servo motors, diesel motors or hydraulic drives.

NEMO® BF Open Throat Progressing Cavity Pump with Auger

The NEMO® BF is used in all industrial markets to provide continuous, pressure-stable, gentle and low-pulsation handling with metering in proportion to rotation speed. This pump is used primarily for highly viscous, compacted and crumbly substances that do not have a tendency to bridge.
