PROBLEM STATEMENT
- The seasonal fluctuation, high chemical oxygen demands, degrees Brix, filter media and alternating pH all have a critical impact on the effective treatment on the effluent emanating from the fishery industry.
- The confined area of a fishery industry makes it critical that the effluent be treated effectively and completely removed. The effluent has to be treated and contained before being discharged into natural streams or being recycled for re-use.
- International quality control, environmental legislation and pressure to re-use water are contributing factors.
CHALLENGE
- The combination of sterilization chemicals, the coagulation of blood, fats, stomach content and other body parts that enter the effluent stream
pose too great a challenge to implement a single treatment solution. - High discharge penalties were incurred.
- Effluent volumes resulted in unpleasant odours and water discolouration.
- CIP wash model also contributed to the quality of water and contamination thereof.
