Advantages and benefits
- Improvement of the discharge values: By reducing the AFS content, the COD and BOD values in the discharge to the receiving water are also improved.
- Provision of process water: The purified water can be used as process water from the wastewater treatment plant effluent, which reduces drinking water consumption.
- Reduction of solids: Filtering effectively removes solids prior to hygienization.
Mechanical treatment
We recommend the RotoSieve drum as an additional treatment stage in the inlet structure. This ensures reliable separation of solids such as Q-tips, which could otherwise pass through the system. A screw mechanism with a pressing and cutting device feeds the solids from the drum into a container.
Use in secondary clarification
The water from the secondary clarifier is often used as process water for cleaning system components. Filtration to approx. 100 - 300 µm is recommended to protect nozzles, valves and fittings.
