Oil & Grease in Wastewater Reductions - Food - Baking

Biological Treatment Summary

The Situation

A food company that manufactures buttermilk biscuits on a mass scale, faced compliance issues with the local pretreatment program. Oil & Grease levels in the company's wastewater discharge were at levels 3-10 times the allowable limits. The company's wastewater discharge system was a series of above ground tanks that transferred wastewater into a large grease trap. The company was forced to have the massive grease trap pumped twice per week.

The Solution

United-Tech recommended a treatment protocol that treated each above ground holding tank during the filling stage. A recommendation was also made to treat the grease trap directly.

The Results

• The company has gone two years without any compliance issues.
  
• The grease trap only requires periodic pumping, saving the company much labor, time and money.
  
• The savings associated with the grease trap pumpings have paid for all product used and the company is now actually saving money.
