Show The Septage Pond has an average depth of 2.2 feet. It is generally stratified into layers from top to bottom consisting of grease, high solids content water, very heavy sludge, and black sand. The Oil Pond has an average depth of 5.1 feet. It is likewise stratified into layers consisting of surface oil, oily sludge, oily water, bottom sludge, and bottom sand. Samples were drawn at various points in the Septage Pond and the Oil Pond. Lab Analyses are tabulated in Table 1 and Table 2 respect ively. PROCESS DESCRIPTION The modular waste processor (MWP-2000) has four main process modules; (1) Rotary Kiln, (2) Secondary Combustor, (3) Heat recovery system, and (4) Pollution control system. A process flow diagram is presented in Figure 2. The Rotary kiln is a refractory lined, carbon steel cylinder mounted horizontally on a trailer and rotated by a trunnion drive mechanism. Solids, including thick sludges and contaminated sand, are transported by belt conveyor to a charging hopper at the front of the kiln. A ram feeder at the bottom of the hopper pushes the solids into the front of the kiln at a controlled feed rate. Kiln outlet gas temperature is maintained around 1300 degrees F to assure vaporization and partial destruction of organic constituents. Solids residence time of approximately 30-40 minutes and kiln rotation of 2-3 rpm are maintained to ensure complete mixing and sufficient burn time for the solids. Residual ash drops out of the back end of the kiln into a water sealed ash receiving tank and is transported by a chaindrag conveyor to a portable ash storage bin.
