Food Processing Wastewater Treatment Case Studies
Animal & Restaurant Grease Protein Recovery
The facility renders animals and restaurant grease as a means to recover protein. The facility generates wastewater at 125,000 gal/day with the following analytical data as shown below.
|Biochemical Oxygen Demand (BOD)||13,000||1600||87.7%|
|Chemical Oxygen Demand (COD)||22,000||4400||80%|
|Nitrogen – Total Kjedahl (TKN)||750||420||44%|
|Total Solids (TS)||7,700||2000||74%|
|Total Suspended Solids (TSS)||4000||40||99%|
|Total Volatile Solids (TVS)||7,200||770||89.3%|

The jar test used Floccin 1103 at a dosage of 1.5 grams/liter which equates to 12.5 lbs/1,000 gallons. Actual dosages will be adjusted depending on the final pond effluent water quality and RWQCB permitted levels. The photos of Untreated and Treated are shown below:
