CIFT TECHINCAL ASSISTANCE PROJECTS JTM Food Group and The Ohio State University worked in effort to reduce the organic load in the wastewater discharged from JTM’s facility. The work focused in two main areas. The “upstream” evaluation implemented membrane filtration in an effort to reclaim water from the beef cooking operation which was identified as a main source of wastewater generation. The “downstream” work used membrane filtration to reduce the organic load of the water discharged to the municipal waste recovery facility. Results from both areas of evaluation have proven feasible in reducing the volume discharged from JTM’s facility as well as reduce the total load in the discharge stream. A Sandridge Food Corporation and Tetra Tech project evaluated wastewater pretreatment techniques in food processing establishments. Testing included onsite, bench-top dissolved air floatation and wastewater samples. Based on the treatability testing results, the wastewater can be treated using a physical/chemical treatment. A coagulation/flocculation system followed by dissolved air flotation for solids removal is proposed to treat the wastewater at Sandridge. Installation of a new treatment system would result in lower surcharges and safeguard the facility against permit exceedance, both capital and operating costs for the proposed system are high. Avure Technologies and The Ohio State University have developed a project to evaluate the effect of water activity on high pressure processing of food products. The purpose of this project is to systematically investigate the microbial death kinetics of selected model bacteria suspended in a meat puree. Results of this study will help introduce high pressure pasteurization for intermediate moisture content category of food products. 10
