4 pump sizes - flow rates from 0 to 25 l/min - one foot print: Allweiler's AEB-DE Progressing Cavity Pump series for dosing applications is incredibly flexible and easier to incorporate than any other pump.

Targeted dosing of flocculants, especially polymers and ferric chloride, plays a central role in effective sludge treatment in wastewater treatment processes. The goal of the process is to make particles in the wastewater easier to separate by agglomerating them. Accurate dosing is required to avoid overdosing or underdosing, both of which can affect the efficiency of wastewater treatment. By optimizing flocculant dosing, Wastewater Treatment Plants (WWTP) can not only improve solids separation and thus treatment performance, but also contribute to environmental protection. Compliance with environmental standards and improvement of water quality are the main objectives. In addition, efficient dosing offers economic benefits by minimizing chemical consumption and reducing wastewater treatment costs.

Pump Requirements

The pump selected for chemical dosing must be able to introduce precise amounts of chemicals, such as polymers, into the sludge at specific times. Precise control is very important to ensure that the chemicals are used to their maximum effect without the risk of over or under dosing, which could lead to degradation of the sludge quality. The pump must be able to respond flexibly to changes in sludge composition and adjust chemical delivery accordingly. In addition, the ability to accurately dose a wide range of chemicals, including flocculants to improve solids removal, is critical.

Our Solution for Your Challenge

Allweiler's progressing cavity pumps are specially designed for demanding chemical metering applications in sludge treatment. Their impressive pumping accuracy and resistance to corrosive media make them the ideal choice for this application.

This range is complemented by ALLMOVE® peristaltic pumps, which are specially designed for pumping difficult and sensitive media. These pumps require no seals or valves, which minimizes maintenance and wear.

Allweiler pumps provide the precision and flexibility needed to efficiently and safely introduce chemicals into the process, achieving optimum thickening while protecting the environment. With their reliability and cost-effectiveness, Allweiler pumps set the standard in sludge treatment.
