A cheese facility producing string cheese had instances when their biological ponds were killed off from the raw wastewater influent. The purpose of the pilot test was to determine if placing a DAF prior to their treatment ponds would improve performance, reduce the accumulation of solids, oils & grease and improve overall discharge. The rest of the existing wastewater treatment system after the biological treatment ponds, included a clarifier and lastly a DAF before discharging directly into the environment.
