摘要：	INDUSTRY regulations dictate that tank trailers utilized to haul foodgrade oils must receive thorough washouts before any new products are introduced. So, to comply with the various local, state and federal EPA requirements in this regard, facilities that clean tank trucks must identify cost-effective water treatment solutions that remove residual oil in wash water before it is discharged into the sewer, and sent to a municipal facility. Failing such regulatory compliance can be costly. After treatment, if the water contains too much residual oil, municipal water treatment centers can refuse to accept it, and levy hefty surcharges and fines. In addition, when recovered efficiently, hydrogenated vegetable oils can be sold to companies making biofuels for a profit. However, every tank truck wash facility is unique and must accommodate a wide range of variables. These can include differing local or state regulatory requirements, the number of trucks washed, truck sizes, types of oils hauled, oil/water ratios, peak periods of use, changing flow rates, environmental conditions, and facility size and layout.
