Treatment of Bakery Grease and Oil Waste
Bio 10V was shown to effectively improve grease and oil waste breakdown
Grease Digestion and Degradation of CBOD for a Large Bakery Operation
Problem
A major full service bakery in Northern Ohio has a pretreatment plant for treatment of bakery waste before discharging wastewater to the local wastewater treatment plant. The average daily wastewater influent to the pretreatment plant has a concentration of the following: 6,000 to over 100,000 mg/l CBOD; average suspended solids of 6,000 mg/l and oil and grease concentrations of 800 to 1,000 mg/l.
Solution
Bio 10V was added to the system with an initial dose of two gallons, and then one quart per day was added for a ten-day period. The maintenance dose was then reduced to one pint per day.
Conclusion
The second aeration tank took on a darker brown color, and there was no longer any type of grease buildup on the paddles of the gravity thickener belt. The dosage of polymer has been reduced by approximately 70%.
The average effluent discharge to the local village POTW has a CBOD average of less than 200 mg/l, TSS of 200-400 mg/l and an average oil and grease of 15 mg/l or less.
These concentrations represent major improvements over the numbers above prior to Bio 10V application.
