Celdar Technology - Cod and Smells Removal In Vinegar Wastewater - Case Study
The customer asked us to evaluate the ELECTROCOAGULATION SYSTEM for the COD and smells removal to be able to drain the treated water into the sewer system.
- Location: ITALY
- PRODUCED WASTEWATER: 15 cubic meter/hour
- Typical problems in wastewater: COD of poorly degradable substances and smell
TREATMENT PRINCIPLES AND AIMS
Another option required was 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: CELDAR
- Trial condition: 7 - 14 Volt / 35 - 70 Ampere
- Temperature increasing (Joule effect): Negligible
- Foam: considerable presence and in compact form (look at the first graph)
The results obtained are satisfactory for carrying out a pre-treatment because the removal of COD deriving from poorly biodegradable substances was excellent and especially the problem of bad odour was solved.
No chemical-physical treatment had succeeded in obtaining a reduction of these parameters; therefore, the customer accepted the installation of an Electrocoagulation
