The precast stormwater filtration treatment unit shall be a continuous deflective separator (CDS®) unit, model PMIU or PMSU as manufactured by CDS Technologies, Inc., 16360 Monterey Road, Suite 250, Morgan Hill, CA 95037. CDS Technologies® may be reached by telephone at (888) 535-7559. Storm Water Filtration Treatment Unit Design Hydraulic Treatment Capacity and Separation Screen Design: The CDS storm water filtration treatment unit shall have a minimum treatment flow capacity as indicated below. This treatment capacity shall be achieved without any flow bypassing the overflow weir of the treatment unit.

The addition of the oil sorbents can ensure the permanent removal of 80% to 90% of the free oil and grease from the storm water runoff. The addition of sorbents enables increased oil and grease capture efficiencies beyond that obtainable by conventional oil baffle systems. Sorbent material shall be added in accordance with the "USE OF OIL SORBENTS" specifications provided by CDS Technologies. D6 DS TECHNOLOGIES PMSU Product Specifications Materials Design for CDS® Unit Manufacture Concrete: Storm water filtration treatment units shall be structurally designed and manufactured from materials per ASTM C478 - 88a "Standard Specification for Precast Reinforced Concrete Manhole Sections". Concrete shall adhere to ASTM specifications C33, .C39, andCl5O. Reinforcement shall consist of wire and/or deformed and plain billet-steel Bars conforming to ASTM Designation A82, Al 85, A496 A497 or A615. Fiberglass: (For these components only: riser, inlet, outlet & oil baffle) CDS® components manufactured from fiberglass shall be per national Bureau of Standards PS-15. The unit shall be coated with isophalic polyester gelcoat and hand laid up of 4 layers 2 oz. mat and 24 oz. bi-directional woven fabric using polyester I to I isophalic resin for excellent chemical resistance and toughness. 3/8 inch laminated lay up schedule for fiberglass unit shall be achieved by these minimum manufacturing procedures. Clean and wax the molds. Apply polyester isophalic gelcoat to the mold, this provides blister resistance. Allow to dry. Then using isophalic polyester resin to wet the-individual layers of mat and the 24 oz. bi-directional woven fabric, hand lay up the 4 layers of 2 oz. mat and fabric on the mold. Cure 8 to 16 hrs. until completely dry before demolding. The parts are then cleaned and smoothed, if needed, of any rough edges and to provide a clean product. Hardware: The separation screen shall be fabricated from stainless steel conforming to AISI Designation A316L. Support structure shall be fabricated from stainless steel conforming to AISI Designation A316L. Fasteners used to install the screen shall be A316 stainless steel. The access cover is to be fabricated of cast iron and designed to support H20 traffic loading, all materials shall conform to ASTM Designation 48-30.
