Our specified a wet Scrubber prior to the Biobed which we manufacture in house. The scrubber has a twin wash system with twin water eliminators consecutively. This Scrubber is mounted on to its own waste water storage tank (again manufactured by AMD) and as you can see a fan unit working after the Scrubber and before the Biobed. All construction is 304 stainless steel including fan contact parts and has been painted too at clients request.
