Celdar Technology - Heavy Metal Removal – Galvanic Industry - Case Study
To optimize the performances of wastewater treatment plant, the customer asked us to evaluate the ELECTROCOAGULATION SYSTEM for the removal of Heavy metals and to be able to drain the treated water into the sewer system.
- Location: POLAND
- PRODUCED WASTEWATER: 25 cubic meter/hour
- Typical problems in wastewater: High Heavy metal residual concentration
TREATMENT PRINCIPLES AND AIMS
Another option required was the ZERO liquid discharge and therefore the possibility of reusing the treated water 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.
- Number of electrodes: 20
- Type of alloy: CELDAR
- Volt applied: 8
- AMPERES: 55
- Reaction time: 1 hour
- Temperature: 38 °C
Final treatment: Flocculation
The removal of the various pollutants: metals and not metals, has a different kinetics but the electrocoagulation system in a limited time is able to give very satisfactory results already after one hour of electrolysis.
The obtained results and working conditions are below:
