PEWE Adams Oil Case Study

Case Study

Adams Oils is a processor, marketer and toll manufacturer of specialty vegetable oils situated in Arbuckle CA for the past 25 years. Founded in 1981 to supply the European & Domestic their customers include the food manufacturing, cosmetic and pharmaceutical industries. Adams has evolved into America’s largest supplier of organic expeller pressed oils all of which are GM Free. Along with growth came increasing wastewater discharge issues. Antiquated systems and an overloaded lagoon became a high priority.

System Solution

PEWE supplied a complete new wastewater and product recovery system. The design utilized the innovative OZ oil/water separator and unique HD2XLRator DAF technology for oil removal and recovery. The system was engineered with state of the art PEWE Command Control panel. Custom equalization/pH tank, pumps and PolyAccu Dose chemical feed subsystems completed the package treatment plant.

Controlled Operation

The wastewater first enters the OZ oil/water separator where free oils readily are collected at the surface without the aid of chemistry. Next the water flows to the equalization tank for balance and pH adjustment.

The widely varying discharge flows necessitate a robust system. The water is fed from the EQ tank to the HD2XLRator DAF for final clarification. A coag and polymer aid the process. Also a special feature of the control package is the TSS Optimization system option selected by Adams during the purchase. This unit automatically monitors the water influent and effluent TSS while automatically adjusting the chemistry to match the current water condition. High oil conditions are dealt with on the fly.

Final Results

The much anticipated start-up day finally arrived. This was after a rigorous shake-down process with PEWE Technical Services personnel. The multi-day event assured a smooth transition to the new system. Mr. Rich Lathrop, Engineering Manager for Adams, is gratified it all came together so well, the water is the best ever and valuable oil is recovered.
