Location: EAST EUROPE
PRODUCED WASTEWATER: 50 cubic meter/hour
Typical problems in wastewater: Sulphides, COD, TSS, Chromium …
TREATMENT PRINCIPLES AND AIMSì
To improve the wastewater management, the customer asked us to evaluate the ELECTROCOAGULATION for the removal of pollutant and to be able to drain the treated water into the sewer system.
Another option required was the ZERO liquid discharge and therefore the possibility of water recycling with the least amount of consumption possible.
This option is possible using an ELECTROCOAGULATION PLANT since no chemicals are used and therefore the physical and chemical characteristics of the water to be treated have little variation compared to the treated water.
The obtained results and working conditions are below
Type of electrodes tried during the lab tests:
- CELDAR Alloys
- Graphite
- Iron
- Stainless Steel low Chromium
