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 fruit processing industry.
- The confined area of a fruit processing plant 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
- High sugar and COD levels impacted by the variants in the pH of the effluent creates an effluent challenge which requires specialist knowledge.
- Effluent volumes resulted in unpleasant odours and water discolouration.
- CIP wash model also contributed to the quality of water and contamination thereof.
ECOSAT SOLUTION
- Our experience in this industry over the past 36 years has given EcoSat privileged knowledge on the imminent water qualities and solution technologies. EcoSat employs chemical, mechanical, and civil engineers as well as other qualified staff in designing our solution, allowing the fruit processing industry to focus on what they are best at.
- EcoSat employed a unique effluent treatment capability to allow for permanent or static installations on a rental or full ownership principle supported by a complete treatment capability. This allows EcoSat to effectively deal with the challenges raised above.
- EcoSat has successfully reduced the sugar content and COD as well as neutralizing the pH in effluent, in the fruit processing industry by utilizing Electrochemical Coagulation (EC), Biological Catalytic Remediation (BCR) and Chemically induced Dissolved Oxygen Flotation (DOF) to substantially reduce the degrees Brix (sugar concentration) in the production of processed fruit, chutneys, fruit juices, dried fruit and purees.
- The data table below represents the results from a manufacturing plant in the Western Cape in South Africa, producing peach, apricot, watermelon, mixed fruit jams and chutneys. According to the results, there is a 60% removal rate.
