The unit can be designed to function as a gravity flow or pumped-driven system. The wastewater flows into an inlet chamber, passes through a baffle and oleophilic coalescing plate pack to separate oil and solids. The discharging effluent comprises the clearer water underneath the floating oils. Depending on the application, the Grit-Oil interceptor may be installed below grade or above ground. The interceptor is typically constructed of precast concrete, steel, or composite material providing years of continuous service. The interceptor is divided into several compartments where wash water discharge oil will coagulate and float to the surface, and sand (grit) will sink to the bottom.INFO@PARKUSA.COM|888-611-7275|WWW.PARKUSA.COM 257'
