Grease skimming involves higher viscosity hydrocarbons. These skimmers must be operated at temperatures that keep the grease fluid. For example, the patented Abanaki Grease Grabber is equipped with heating elements that keep the grease in a liquid state for easy discharge from the skimmer. However, if floating grease has furmed into solid clumps or mats in the tank holding the skimmer, a spray bar, aerator or other mechanical apparatus can be used tu break up grease and facilitate skimming.
Often, a skimmer by itself can achieve the desired level of water purity. In more demanding situatiuns, skimming is a custeffective means of remuving most of the oil before using more complicated and costly treatments such as coalescers, membrane filters and chemical processes.
Typical applications for industrial oil skimmers include: wastewater sumps; coolants and dutting fluids; heat treating; parts washers; food processing facilities; parking lots, garages and service facilities; outdoor punds, lakes, basins; and recovery/ monitoring wells.
