With S.sensing® CS, our customer increased revenue in oil and grease sale while improving overall health of their plant

Background
The client’s state-of-the-art, dissolved air flotation (DAF) system in their flagship beef processing plant could not consistently recover the level of fat, oil and grease (FOG) possible from the wastewater stream. One to two pounds of oil and grease harvested per animal was escaping the plant uncaptured. 

Prior to working with Kurita, the client injected coagulant and flocculant into their wastewater stream in hopes of achieving better FOG recovery at the DAF. However, without an effective method to fluctuate chemical injection volume based on variable wastewater flow and loading or having the ability to accurately inject the exact volume of chemical necessary to recover all the oil and grease available in the wastewater, their efforts were unsuccessful. They continued to record higher than desirable levels of FOG contaminants in their lagoons, which reduced operating capacity.

Objectives

• Increase FOG Recovery
• Correct dosage when needed
