Patent abstract
A mobile apparatus and method of operation for the pretreatment of wastewater to remove and concentrate fats, oils, grease and settled solids using vacuum flotation and a clarifier and returning the pretreated wastewater to the source structure, tank or sewer system. The vacuum flotation process is enhanced by injecting hydrogen peroxide to increase the dissolved oxygen concentration and a cationic emulsion polymer as a coagulant to the wastewater prior to removal into the vacuum flotation tank by vacuum pumping.
