The Project will include any disassembly and reassembly of existing clarifier equipment for the proper removal of existing tubes and installation of the new tube settler system; includes remove and reinstall of stainless steel plates that circle the bell and lay on top of the tube settlers. Cathodic protection systems for the four (4) clarifiers will be replaced in kind. Waterproof coating of all four (4) clarifiers is required, including recoating all of the normally submerged carbon steel elements. Major elements include the rake mechanism, center column, reaction well, draft tube, impeller, drive cage, support structure, influent pipe, and minor miscellaneous elements. Preparation of all surfaces to be coated shall be included. Air Compressor Replacement of one 30 HP air compressor with new 40 HP variable speed rotary air compressor.
