The most oil retention. common way is using the effluent flow rate as determined by either the equipment that is used in the area serviced or using DFUs and converting the total DFU to GPM. OPERATION Additionally, there is a method of sizing outlined in the The function of the AquaSweep, just as the Sand-Oil CMPInternational Plumbing Code as outlined in section 1003.4.2.2 Separator, is to intercept free oils/solids and retain them forGarages and Service Stations: periodic removal. The wastewater is treated by the separator in two stages. The initial stage of treatment occurs as theoil separators shall have a minimum capacity of six cubic inflow strikes a corrugated diffusion plate. This process isfeet (0.168 m3) for the first 100 square feet (9.3 m2) of area to known as the Buffalo-Morse Principle. Solids and oil arebe drained, plus 1 cubic foot (0.28 m3) for each additional 100 separated through velocity reduction and sinusoidal flowsquare feet (9.3 m2) of area to be drained into the separatorpatterns. Heavy solids settle and 100 percent oil slugs rise immediately to the surface.

Under laminar flow conditions, buoyancy forces cause oil droplets to rise until they adhere themselves to the oleophilic plates.
