Lesson 15 Handling and Disposal of Process Wastes
During each cleaning roughly 0.2 inches of sand is removed from the top of the filter producing 28 cubic inches of waste per filter. The sand could be cleaned and re used but it is generally disposed of at a landfill. The sand will most likely be nonhazardous but the landfill may require that a TCLP test be performed to verify this.

Sand Casting Process
Sand casting can produce aluminum blocks like those of cast iron. A typical resin bonded mold is shown in Fig. 2.36. In comparison with cast iron sand casting of aluminum is not so easy because oxide entrapment and shrinkage defects are likely to occur. Cast iron does not cause this type of problem.
