BMS manufactures a full range of Petrol & Oil Interceptors (Separators) from 1,000 – 100,000 L including Full Retention, By-Pass & Forecourt Interceptors for all requirements. All BMS Interceptors are manufactured under an NSAI verified ISO 9001:2008 Quality Management System & to the new European Standard; PR EN 858 1&2.
Surface water from sealed surfaces flows away via drainage to receiving waters, sewers or to soakaways. If there is potential for petrol/oil spills onto these surfaces e.g. car parks, forecourts, roads, garages and depots, it is vital to intercept/separate any petrol/oil contaminants to prevent damage to the surrounding environment. The petrol/oil is then held within the interceptor for safe removal. BMS Petrol/Oil Interceptors perform this role. BMS manufactures a full range of interceptors for all applications. All BMS Interceptors are manufactured in rot proof and durable Glass Reinforced Plastic (GRP) It is critical that the correct interceptor is selected depending on a sites particular requirements to ensure that they function correctly. A number of different factors need to be taken into account when selecting the correct interceptor.

BMS have introduced a full set of Petrol Interceptor/Holding Tank Sizing & Selection Charts to help you easily size and select an Interceptor/Holding Tank suitable for your requirements. They can be downloaded at this link.
BMS Three Chamber Full Retention interceptors are available in a wide range of sizes varying from 1,100 L up to 100,000 L. Larger sizes can be accommodated on order. Full Retention interceptors are used in areas where there is a high risk of petrol/oil contaminating the on-site drainage e.g. Fuel Distribution Depots, Scrap Yards, Car/ Vehicle Workshops and Washdown areas.
Under normal flow conditions, the BMS Full Retention Interceptor is designed to retain the full contents of an oil spill or contamination up to flows of 50 mm/hr.
A requirement of full retention interceptors is that they must have a large enough capacity to prevent pollutants being flushed through the unit during storm conditions.
In the case of larger drainage areas such as car parks, airports and industrial estates, Full Retention Interceptors are not practical, as they would require very large full retention petrol interceptors, making production, installation and handling more costly. A practical and economical solution to this problem is the BMS Bypass Interceptor range.
Under normal flow conditions, the BMS Bypass Interceptor will separate and retain silt and pollutants such as oil and petrol prior to discharge.
In storm conditions, when periods of peak flow are experienced, it will treat a certain percentage of the maximum flow whilst at the same time allowing the excess to by-pass the retention chamber of the unit.
As contaminated water enters the first chamber, pollutants float to the surface. Due to the unique internal design; vortex formation occurs at the by-pass pipe resulting in the pollutants being skimmed off the surface and become trapped allowing the uncontaminated water to discharge from the interceptor.
When storm flows intensity increases, the vortex pipe floods thus restricting the flow from the first chamber to the retention chamber. As a result of the increase in water level in the first chamber, hydraulic pressure increases, forcing the majority of the water through the by-pass weir and into the chamber to discharge.
BMS have developed their ‘Filterceptor’ range of Forecourt Separators in line with the proposed new CEN European Standard for light liquid separators. It doubles both as an interceptor and separator of pollutants on the petrol station forecourt where there is a significant risk of petrol or oil spillage. The Filterceptor is designed to contain the maximum contents of a spillage from a fuel delivery tanker compartment.
BMS Filterceptors Forecourt Interceptors
Doubles as both an Interceptor and a Separator of pollutants on the petrol forecourt, where there is a significant risk of petrol or oil spillage. They are designed to contain the maximum contents of a spillage from a fuel tanker compartment.
The Filterceptor unit contains an automatic shut-off valve and coalescer and is specifically designed for applications where the requirement for hydrocarbon pollutant concentration from the unit is 5 mg/l or less. When a change in the specific gravity of the liquid present in the unit occurs or when water present is replaced by less dense hydrocarbon pollutants a specially calibrated ball will drop and seal the outlet from the Filterceptor. The coalescer filter consists of a polyurethane open cell foam enclosed in a perforated PVC housing. Untreated flow cannot leave the Filterceptor without first passing through the coalescer filter. An optional extra is an oil level probe and alarm system.
