Physico-chemical treatment remains an important water treatment technology. We use various techniques for this, such as:
• pH control
• chemical dosage
• detoxification through oxidation or reduction
• dewatering (through a centrifuge or filter press)
RUN-THROUGH OR BATCH SYSTEMS
Our lab examines the relevant waste water flows in function of a correct dimensioning of the designated techniques. We offer the physico-chemical treatment in a throughput/ run-through or batch system. Often a conventional installation with detoxification, neutralization and dewatering (ONO) appears to be the right choice. With rinse-water, we sometimes combine this with ion exchangers in an open or closed circuit.
CLOSED-LOOP PHYSICO-CHEMISTRY IN THE CONCRETE SECTOR
Subsequently we remove the precipitated solids via filtration. Filtration (with big bags or a filter press) is a robust solution to absorb all of the sludge from the waste water. By bundling different physico-chemical techniques, such as flocculation, sedimentation and pH correction with CO2, it is possible to achieve the zero-discharge status.
