![]() ![]() Leak and level sensors, alarm/control panels, influent, effluent and oil pump systems along with High-LINK® monitoring systems are available. Interceptors can be sized for greater volumes and retention time and are watertight and pressure or vacuum-testable in the field if needed.Īn extensive range of standard sizes and capacities is available along with customization of capacity, arrangement, dimensions, and pipe penetration locations to fit your specific requirements. Interceptors are available in double-wall construction for locations where regulations dictate. BobPE (Civil/Environmental) 24 Mar 03 10:24. Invert for the catch basin is usually given as the elevation of the lowest pipe (in or out) of the catch basin. The highest point of the inner diameter is known as the overt or crown. OSI sizing and construction conforms to recognized plumbing codes and meets or exceeds many municipal industrial sewer pretreatment regulations. They indicate the lowest point of the inner diameter of the pipe. Designed to accept gravity flow, the interceptor’s volume and design, provide ample retention time to enhance the removal of sand, grit, free oil and grease to be removed from the wastewater due to their differences in specific gravity. ![]() Denser, cleaner water flows through the compartment(s) until it is discharged from the interceptor. Oil/sand interceptors contain one to four compartments (basins) where oil separates and floats to the surface, while sand and grit settle to the bottom sludge baffle. Additionally, our elevator sump pump and oil interceptors are designed specifically to remove hydraulic and other oils and volatile liquids from in and around elevator pits. Highland Tank’s Oil/Sand Interceptor (OSI) is treatment tank designed to intercept and collect sand, grit, free-oil and grease (hydrocarbons and other petroleum products) in a wastewater flow, and prevent their entry into the sanitary sewer system. ![]()
