New full scale equipment and modification to the existing standard waste treatment equipment were installed at the Swift & Company modern, high-volume, edible fat and oil refining plant at Bradley, Illinois, complete with necessary controls and instrumentation to study methods for removing and upgrading the fatty materials for resale. An in-plant survey was conducted. The waste streams were characterized as to source, flow rate, and either solubles, suspended solids and BOD content. Synthetic acrylamide polymers were laboratory tested as flocculants in combination mainly with alum for plant waste water clarification. Cathodic protection devices and impressed current successfully controlled corrosion and build-up of solids on the walls of the existing Skimmer and Air Flotation Units. A DeLaval PX-213 bowl opening, disc stack, centrifuge was tested to concentrate and upgrade the removed fatty materials after caustic and sulfuric acid treatment. An overall economic evaluation indicated 7000 pounds of oil recovered would offset 60% of the total daily direct operating costs for the waste treatment system, including the oil reclaiming system.
