General
FROSCO Oil Interceptor works on the principle that oils are lighter than water and thus gravity causes the oil to rise and the water to fall. It is designed to separate oils and other light density volatile liquids which are discharged into the drainage system.

In commercial establishments, the spillages of oil or diesel could occur such as garages, transport workshops, diesel re-fueling and storage areas, and where vehicles or plant are washed down or steam cleaned.

Function
The direct and indirect discharge of oily waste water into the natural waterways has a disastrous impact on the environment.

The installation of FROSCO Oil Interceptor in drain lines will help to prevent the pollution of rivers, streams, drainage system and water treatment plants.

Mechanical Operation of FROSCO Oil Interceptor
1. Perforated Bucket Baffles Assembly
When the influent entering the interceptor, the perforated bucket baffle assembly will trap and collect chips, particles or other sediment which are frequently present in industrial waste and could clog the drainage system.

2. Baffles Assembly
It will help to minimize the velocity and turbulence of the incoming waste water and permit the oil efficiently separate and rise above the normal establishes water line of the interceptor.

3. Deep Seal Integral Trap
The trap is to avoid the floating oil in the interceptor being escaped out into outlet drain lines.

4. Gravity Oil Draln-off Assembly
By automatic or manual means, the floating oil flows through an adjustable draw-off point to a sump or a similar storage container awaiting disposal. Please refer to 'Collection of floating oil' column for other means of oil collection.

5. Interceptor Vents
To eliminate pressure build-up inside the interceptor, a connection on each side of the interceptor body allows the venting of the interceptor.
