Description
Oil interceptors are typically used to intercept in low flow drain lines where small quantities of oils, sediment and other liquid contaminants. These drain lines may come from variety of facilities including covered parking garages, machine shops, service stations, and manufacturing facilities.
Oil interceptors are simple systems which include a baffle plate, a solids bucket, and a separation area. As the water enters into the interceptor, a baffle plate reduces the flow of the incoming water which helps to drop out some solids and sludge. A low flow rate and little turbulence permits the oils and other light density to slowly separate from the water and rise to the top of the separation area. From there, relatively oil-free water is discharged to the sewer.
