Abstract: A filtering assembly is provided for removal of certain substances from a solution. More particularly, apparatus are provided for removal of hazardous or environmentally unacceptable chemicals from a first solution before it is discharged. The device includes a cylindrical housing having a spaced apart inlet and outlet. Adjacent the inlet, a metal precipitate chamber is provided to collect precipitates which includes rolled fiberglass for capturing precipitates. A filter subassembly is provided on the downstream side of the inlet. The solution is then directed through an adsorption chamber containing activated carbon. In this chamber, certain chemicals are absorbed onto the carbon. A second embodiment of the invention provides multiple inlets for chemicals being introduced into the chamber as well as a water inlet. The chemical inlets are provided with distribution manifolds to evenly disburse the incoming solution within the chamber.
