Wastewater Treatment for an Ice Cream Factory

One of the southeast's largest ice cream processors was having a problem with excessive FOG (fats, oils and grease) in their effluent wastewater. The levels of FOG in their water were far above the county's limits and were causing problems in the county's lift stations. As a result, the county had given the plant a deadline of 6 months to fix the issue or face closure of the facility altogether. Furthermore, an odor problem had also lingered around the processor's old wastewater treatment system because it had been undersized and overwhelmed with their high strength wastewater.

Wastewater treatment system for an ice cream factory

Ice cream factory wastewater treatment requirements

  1. Reduce fats in wastewater to allowable standards mandated by the local county.
  2. Support permitting for a new wastewater treatment system with county authorities.
  3. Eliminate offensive odors produced by biological treatment.

The solution

Ecologix determined that a new treatment system was required to bring the facility into compliance and provided support for the required county permits.

The physical and chemical treatment system included an equalization tank, continuous removal of free-floating fats, chemical reaction tanks, a dissolved air flotation system, and sludge dewatering. It replaced a failing system, removes FOG and suspended solids, reduces BOD, and eliminates offensive odors.

Final results

  • FOG was reduced from an average of 1,290 mg/L to less than 10 mg/L.
  • Total suspended solids were reduced by over 99%.
  • Biochemical oxygen demand was reduced by almost 45%.
