Each unit to be capable of providing a dosage of 90,000 micro-watt seconds per square center @ 254 nm, at a flow of 175 gpm, based on 90% water transmission. Lamps shall be low pressure mercury vapor with hard glass enclosure, having a guarantee of 9,000 hours to end of life at 60% of original output. All wetted parts shall be 316L stainless steel, welded using the plasma fusion arc method, polished and passivated after fabrication. Heads shall be threaded for removal for interior access. Exterior non-wetted surfaces shall be polished and passivated after fabrication. Manufacturer's standard controls shall be furnished and mounted in a NEMA 4X panel. Include independently fused fan cooling system, light-out warning LED display, and elapsed hour meter. Qty. 2 each. 02) Rotary drum filter. Unit shall consist of a screened drum driven by an electric motor through a gear reducer, revolving inside a fiberglass surround tank. The inlet water enters the interior of the screen, and the discharge is on the exterior of the screen. The unit shall be designed so that the sludge drops into a discharge trough as the screen revolves. A spray system shall be included to clean the screen at a minimum spray pressure of 80 psi, with discharge into the trough. The unit shall be constructed of 316L stainless steel, fiberglass, and suitable plastics, with the basin of fiberglass, the drum frame of 316 stainless, and the screen panels of plastic. Other parts constructed so as to hold the amount of stainless in contact with the water stream to a minimum. The motor and gear reducer shall be enclosed and exterior mounted. The minimum flow rate is 25 pm TSS, using 60 micron shall be not less than 365 gpm. Rotational speed 5 rpm. Maximum submergence of drum 60% (controlled by exterior standpipe by others). The rotation and backwashing shall be automatic, actuated by the increase of the head on the drum. The controls to accomplish this shall be enclosed in a NEMA-X box (except for a low voltage float control). Spare parts with the unit must include a complete elastomeric drum seal, two screen panels, and twenty screen patching plugs. Qty. 1 ea. 03) Sand filters, non-metallic. Must be of non-corrosive construction (no metals in contact with water). Filter body fiberglass and polyester resin with a working pressure of 50 psi. Stand, flanges, diffusers, and laterals of PVC and/or polypropylene construction. Filter area must be not less than 26 sq. ft. Tank diameter not to exceed six feet. Minimum capacity 1,600 pounds of gravel and 6,000 pounds of silica sand. Four inch, 150 pound water connection flanges. Must include dual gages with brackets and fittings for tapes into inlet and outlet by owner. Fill lid, manual air relief valve, water drain and sand drain plugs. MUST BE COMMERCIAL PRODUCTS IN USE FOR AT LEAST FIVE YEARS, CUSTOM MADE PRODUCTS NOT ALLOWED. Provide catalog cuts/brochures of proposed system.Provide Federal tax ID number and DUNS number with quote. State if small-, minority-, or women-owned business with quote.
