Functionality of AEP Oil Interceptor

i) Separation of Oil
The effluent enters inlet of the unit at high velocity flow rate carry with it the mixtures of oil, solid sediment and wastewater to the sediment bucket in the first chamber which retains the solid materials. Oil being lighter than water flows through to the second filtering chamber.

ii) Removal of Oil
The chamber consists of two filtering stages:

a) Coalescer Pack Unit
Oil will pass through a coalescer pack unit specially designed to reduce water turbulent flow and also to separate thicker oil particles into smaller particles for draw-off in the later process.

b) Coalescer Plates Unit
The oil particles that managed to pass through the first filter unit will be further trapped in the second chamber which is specially designed to ensure the small particles are captured and flow upwards to the water surface and provide enough retention time before being removed by an adjustable draw-off point to a sump tank, allowing only clean water to be discharged.

iii) Removal of Solids
The bucket that retains the solid materials needs to be emptied on an appropriate frequency to ensure no blockage that could cause interruption to the water flow.
