Our Products and Solutions

WAWACS Sedimentation Plants

In the sedimentation reactor, the flocs settle to the bottom while clear water forms above them. The clear water is discharged via valves and a belt filter. The remaining flocs are transported to a container for further dewatering. The treated water is either reused or discharged into the sewer system.

Industrial wastewater is as individual as the operation it comes from. That is why every WAWACS project begins with a thorough analysis of your specific situation: What contaminants are present? What volumes need to be treated? What legal discharge limits must be met?
Based on this analysis, we work with you to determine the most suitable treatment process – whether flotation, sedimentation, neutralization or a combination of several stages. The result is a system precisely tailored to your requirements, designed for long-term reliable operation.

Functional Description

The wastewater is first treated in a pre-treatment system that includes sedimentation tanks and an oil or grease separator. Emulsions are then pumped from a collection tank into the sedimentation system. Separation and flocculation agents are added to bind pollutants and break down emulsions. The pH level is monitored and adjusted with acid or alkali if necessary.
In the sedimentation reactor, flocs settle at the bottom while clear water forms above. The clear water is discharged via valves and a belt filter. Remaining flocs are transported to a container for further dewatering, and the purified water is either reused or discharged into the sewer. Sludge is dewatered using a chamber filter press or a decanter and then disposed of.
Monitoring units detect and report faults or material shortages, displaying alerts visually and acoustically. The system allows flexible adjustment of treatment times and efficient chemical dosing for resource-efficient operation.
