Hydro-Flo Technologies - TotlSep Oil/Water Separator - Fiberglass Construction Engineering Specification A. Equipment Design Criteria The separator shall be a specially fabricated rectangular channel tank. The separation process shall be fully automatic requiring no moving parts. The design of the separator shall satisfy the requirements of API PUBLICATION 421, Feb. 1990 on DESIGN & OPERATION OF OIL/WATER SEPARATORS and Stoke's law. Performance enhancement shall be achieved by the use of DYNA-PAK cross corrugated coalescing media. B. Materials of Construction (standard configuration) The separator and lid shall be a specially fabricated rectangular channel fiberglass tank constructed of multiple layers of minimum 50% random weave fiberglass fabric and the balance consisting of chop strand all hand layered with premium grade isopthalic polyester fiberglass resin. All exterior surfaces of the fabricated oil/water separator tank shall be covered with a continuous layer of chemically resistant, ultraviolet stabilized, polyester gelcoat The tank fittings are to be premium quality FRP fittings suitably reinforced and glassed into the body of the oil water separator. Interior flow piping (skimmer, inlet and outlet diffusion pipes to be schedule 80 PVC. The coalescing media is PVC, 10 mil thick. C. Influent Diffusion Chamber The flow shall enter the separator submerged, through an influent diffusion chamber. Dispersion across the depth and width of the DYNA-PAK is to be achieved through the use of a non-clog diffuser. Heavy solids that fall out of suspension here shall be channeled to the sludge collection chamber. D. Separation Chamber The Separation Chamber shall be fitted with DYNA-PAK cross corrugated coalescing media. Adequate space is to be left before and after the chamber to prevent short circuiting through the pack. Separation Chamber. Adequate space is to be left before and after the chamber to prevent short circuiting through the pack. A total of ____ cubic feet of coalescing media is provided with ½, ¾, or 1.25” spacing providing ______ft3 of coalescing surface area. E. Sludge Collection Chamber The sludge collection chamber shall be located directly beneath the coalescing media pack and provide ample storage capacity for the settled sludge. The sides of the chamber shall be sloped at 45 degrees to insure easy and complete removal of the settled sludge. F. Rotary Pipe Oil Skimmer The oil skimmer shall be located at the effluent end of the separation chamber and incorporate an adjustable oil skimming weir. The rotating action is provided to allow for oil skimming weir elevation adjustment. Rotating action to be achieved by the use of rotating unions with grease zerk fittings for lubrication. G. Recovered Product Storage Chamber The recovered product storage chamber shall be located beneath the separation chamber and include fittings for pump suction, atmospheric vent, and both high and low level controls. H. Effluent Chamber The aqueous phase leaving the DYNA-PAK shall pass under the oil retention baffle and up over the effluent weir, which shall maintain the liquid level throughout the separator. I. Removable Lids The entire separator shall be covered with a removable lid. The lid shall come with a D shaped, vapor tight, seal. The lid shall be held in place, and the seal compressed, by adjustable 1/2 turn draw latches. J. Coalescing Media The coalescing media pack shall be fabricated of oleophilic cross corrugated coalescing media manufactured by HYDRO-FLO TECHNOLOGIES. K. The oil/water separator shall be a Hydro-Flo Technologies TotlSep Series - Model “TSXX-FXX“ or equal.
