FRP Oil Interceptor

Rainwater and waste polluted by light liquids such as accumulate when vehicles are being repaired, filled with petrol or cleaned, in installations used for the storage, filling or handling of fuels, oils or lubricants or for the storage or handling of material contaminated with petrol or fuel oil, are no to be allowed to enter public sewer without prior treatment, nor is the discharge of any type of lubricant permitted. Thus, rainwater and wastewater likely to contain the above-mentioned materials shall be discharge via interceptor.

Type of Pollutants

The primary pollutant in the wastewater (influent) is hydrocarbon and secondary pollutants include floatable debris, sand and silt. The wastewater treatment process shall therefore design to remove both primary and secondary pollutants. The treatment process is designed by exploiting the specific density properties of the various pollutants.

	Remove of Floatable Debris
	Floatable debris like plastic, paper, twigs and leaves are removed using a filter mesh basket installed upstream to the oil interceptor and silt trap along the storm or perimeter drain. The basket shall be periodically cleaned to ensure that all debris trapped does not clogged up the perimeter drain.
	Removable of settleabe solids
	Settleabe solids which forms the major bulk of secondary pollutants can be easily separated out using a silt trap which employ the principle tanks. Sand and grits of various sizes will settle down at different rates as governed by Stoke law.
	Removable of hydrocarbon products
	Hydrocarbon pollutants are lighter than water and usually have a specific density of 0.85. Again using the concept of settling tank and principle of Stoke law, an efficient separator could be designed to separate the hydrocarbon from the water. This separator is often called the oil interceptor. The clarified effluent is now given a final polish by passing the effluent through n activated carbon filter to remove any minute traces of hydrocarbon present. The final effluent shall now be safely discharged into any waterway.

Process Summary

Oil Interceptor Design

The principle employed in the AceON oil separator process is similar to that Inclined Parallel Plates. The concept is an adaptation of the settling tank except the droplets rises up instead of settling down and be introduction of parallel plates reduces the distance the oil droplets have to travel before being “captured”. Once the droplets are captured on the underside of the plates, they go through a process of coalescing (small droplets fusing together to form larger droplets). The plates are inclined so that the enlarged oil droplets start to wick along the plate and finally float to the top of the interceptor. The fine silt will settle down on the topside of the inclined plate and the silt on the plate will work itself down by virtue of gravity and this will prevent plugging. The inclined parallel plates are therefore termed as coalescing media.

The “AceON Oil Interceptor” utilizes “cross flow film fill” as coalescing media because of the extended surface achieved by its curvature geometry. The film is constructed using Pvc sheet, which is chemical proof and tough. Minute oil droplets within the wastewater stream are attracted to these media and once the oil droplets attached themselves to the surfaces of the film they rapidly coalesce and form larger oil droplets for more rapid oil separation.
