Dairy Application: System Solution

One of the largest consumer goods companies in the world and leader in foods and refreshment, health and beauty, and home care markets came to FRC to solve a problem at one of their ice cream facilities.  The plant was generating wastewater with high levels of Total Suspended Solids (TSS) and Fats, Oils, and Grease (FOG) and was required to bring their wastewater into compliance levels so it could be discharged to the city.

FRC’s design for most dairy applications simplifies the chemical dosing procedures while using low-cost chemicals, limits the footprint of the entire wastewater treatment system, and reduces the odors commonly associated with dairy processing operations.

Compared to conventional wastewater treatment processes, the FRC process features the following:

  1. Straightforward low-cost chemistry
  2. Less equalization needed which limits footprint
  3. Higher dry solids content in DAF sludge resulting in less sludge hauling
  4. Odor reduction
  5. Self-sustaining process

Design Data

FRC Solution

  • Rotary Drum Screen – Remove fruits, nuts, and other ice cream toppings
  • Equalization – Allows for homogenization of the wastewater. With the FRC Process, the tank size is smaller compared to conventional wastewater treatment processes
  • Flocculator #1 – Since pH > 10, a rough pH adjustment is needed to lower pH
  • Flocculator #2 – The FRC custom chemical regimen is used to “break out” the emulsification
  • High Rate DAF – Float the precipitated emulsification, yielding clean effluent water
  • Flocculator #3 – Coarse pH adjustment to ensure pH in permit range prior to discharge
