Waste Water Treatment
The waste water treatment is a complex process of caring for the
valuable resource of water and prevention of environmental damage. Optimally designed processes ensure efficient cleaning of the waste water and save money.
Many processes are based on dosing of chemicals – often controlled and automated. ProMinent not only has years of experience in water treatment, specifically in wastewater treatment for example, but can also offer a comprehensive and flexible range of Chemical Fluid Handling equipment.
Depending on the nature of the wastewater and use in municipal water treatment or in industrial wastewater treatment, physical, chemical or biological methods are employed. ProMinent ensures optimal design of the entire process for water treatment and for compliance with all statutory regulations – worldwide.
- pH value neutralization: controlled dosing of acids/alkalis
- Control of the oxygen content in the aeration basins of municipal sewage plants
- Controlled dosing of reducing/oxidising agents for decontamination of process water containing chromate or cyanide, for example
- Phosphate precipitation: dosing of iron(III) chloride
- Optimal flocculation of precipitable pollutants: dosing of polyelectrolyte solution
- Removal of precipitable pollutants in the gravity filter
- Sludge dewatering by polyelectrolyte dosing
- Desalination of process waters by reverse osmosis
- In some countries: controlled dosing of disinfectants in the postclarification basin and measured value-dependent destruction of excess disinfectant before the wastewater is discharged back to nature.
