OIL SEPARATORS PETROL INTERCEPTORS

The safest answer for pollution control and the environmentFuel/oil SeparatorsQuality, high performance light liquid separators52xn8 January 2013Tests being carried out at HR Wallingford, for obtaining ‘Light Liquid Separator Test Performance’ certificates. The average hydrocarbon concentration measured for all SPEL Separators tested was 0.67mg/l and well within the required 5mg/l.A substantial amount of oil pollution is collected on sites such as garage fore courts, large car parks and fuel storage depots and this must be intercepted to avoid the risk of prosecution.The Environment Agency has published Pollution Prevention Guidelines “Use and Design of Oil Separators in Surface Water Drainage Systems: PPG3”. These set out the standards with which sepa rators must comply and assist in deciding on the need for a separator at a site and the size and type that is appropriate.These Pollution Prevention Guidelines PPG3 require separators to be tested in accordance with the standard test procedure based upon the European Standard BS EN 858-1:2002.SPEL Separators are compliant to the European Standard BS EN 858-1, the Environment Agency’s Pollution Prevention Guidelines PPG3 and the Construction Products Regulations.Inside front cover: SPEL Stormceptor series 600 class 2 by-pass separator for a catchment area of 30 hectares. NSB 500.149yearsTechnical innovation & progressLeaks and spillages of oil and fuel are washed down drains every time it rains and, unless intercepted, find their way into water courses, polluting reservoirs and rivers. This can have a disastrous effect on plants and wildlife.Protect the environment the most reliable and efficient waySpecify SPEL SeparatorsSPEL Products is a Quality Assured Company under BS EN ISO 9001:2008 – with our own modern manufacturing plant the highest standard of product quality and control are ensured.SPEL Separators are filament wound by an advanced, patented, chop hoop filament winding process. This process produces not only circumferential strength as found in helical wound tanks, but also high longitudinal strength. The interlaminar shear strength permits tanks to be cut for manholes and pipework without undue loss in strength.SPEL fuel/oil separators – for high performance and low maintenance over a long life spanLeft: Bristol International Airport SPEL Puraceptor Class 1 full retention separator NS 942 and ‘automatic’ Econoskim system.The manufacturing process is carefully monitored with a digital read out system.

Quality products from a quality assured companySPEL Stormceptor® class 1 by-pass separatorsTypical sitesInfrequent light contamination – potential for small spills only eg. car parks. Note: class 2 available if connection to foul sewer.General descriptionSPEL Stormceptors are the most widely used separators where it is acceptable to treat the ‘first flush’ ie. flows according to the nominal size (NSB) generated by rainfall rates of up to 6.5mm/hour. This covers most rainfall events in the UK. Any excess rainfall is by-passed without treatment. Without silt capacity.SC – with silt capacity.Single chamber models.Two chamber models.General descriptionSPEL Puraceptor full retention separators treat the full flow generated by a rainfall intensity of 65mm/hour. They have been designed and tested to meet the stringent European Standard BS EN 858-1 for installations for separation of light liquids where the maximum hydrocarbon concentration in the outlet does not exceed 5mg/l.Two chamber models provide protection to the coalescer foam inserts from silt and heavy fuel/oil contamination resulting in less frequent maintenance and easier cleaning of the coalescer foam inserts.The SPEL Stormceptor was the first Environment Agency listed class 1 by-pass separator to BS EN 858-1:2002 (2001).Typical sites two chamber• High risk oil/fuel storage and handling areas.• Filling stations (SPEL Puraceptor forecourt separator FP2CSC).• Heavily contaminated industrial areas, commercial vehicle/plant maintenance yards, power/sub stations, fire training grounds and railway light maintenance and fuelling depots.SPEL Puraceptor® class 1 full retention separators – single and two chamber models Typical sites single chamber• Medium to high risk oil/fuel storage and handling areas.• Filling stations (SPEL Puraceptor forecourt separator FP1CSC). • Commercial vehicle/plant maintenance yards and heavily contaminated industrial areas.Typical sitesWhere risk of regular contamination of surface water run off and connection is to foul sewer eg. vehicle maintenance area, goods vehicle parking/vehicle wash area.General descriptionFull retention separators treat the full flow generated by a rainfall intensity of 65mm/hour. They are fitted with an automatic closure device ACD.Features • Good access to all parts for desludging.• Dip pipe inlet for minimum turbulence and to prevent inflammable vapours passing upstream in drainage system.• Automatic closure device (ACD) closes the separator off automatically once the maximum storage capacity of light liquid pollutants is reached, e.g. major fuel spillage, so preventing them passing into the drain.• Designed for high performance and low maintenance over a long life span.Notes to accompany the flowchart1. You must seek prior permission from your local sewer provider before you decide which separator to install and before you make any discharge.2. You must seek prior permission from the Environment Agency before you decide which separator to install. Is there a risk of oil contaminating the drainage from the site ?YESYESYESYESIF NOT SUITABLEYESYESYESYESNOYESThe use of SUDS should be considered at all sites and they should be incorporated where suitable. SUDS can be used to polish the effluent from these separators before it enters the environment 6. Risk of infrequent light contamination and potential for small spills only. e.g. car park.Risk of regular contamination of surface water run off with oil and/or risk of larger spills. e.g. vehicle maintenance area, goods vehicle parking or vehicle manoeuvring 5. Drainage will also contain dissolved oils, detergents or degreasers such as vehicle wash water and trade effluents. e.g. industrial sites. Fuel oils are delivered to and dispensed on site. e.g. retail fuel forecourts. Very low risk of oil contamination. e.g. roof water. Separator not required.Source control SUDS should be considered where possible. Roof/clean water should not be passed through the separator unless the size of the unit is increased accordingly. Trade effluents must be directed to the foul sewer 1. It may need to pass through a SPEL full retention separator before discharge to sewer to remove free oils.

In certain circumstances, the sewer provider may require a class 1 separator for discharges to sewer to prevent explosive atmospheres from being generated.5. Drainage from higher risk areas such as vehicle maintenance yards and goods vehicle parking areas should be connected to foul sewer in preference to surface water.6. In certain circumstances, a separator may be one of the devices used in the SUDS scheme. Ask the Environment Agency for advice.How to select and specify to the Environment Agency’s Pollution Prevention Guidelines PPG33Flow according to nominal size (NSB)The polluted surface water first enters the primary chamber where silt settles out and is retained. The fuel, oil and other pollutants lighter than water, rise to the surface and are efficiently skimmed off and transferred to the separation chamber.All flows within the nominal size pass through the separation chamber, where the quiescent conditions allow the pollutants to separate out efficiently. Water from the cleanest zone in the separation chamber flows through a coalescer unit, to remove smaller globules of oil, up to the junction chamber and thence to the outlet.Storm flows above NSBDuring a storm the level in the primary chamber rises and the stormwater passes over the weir into the junction chamber and to the outlet.The design keeps the turbulence within the separation chamber to a minimum which avoids disturbing the contaminants retained.When you look into SPEL tanks you can see the differenceSPEL Stormceptor by-pass separators are being used effectively throughout the UK and abroad, since 1985. All sizes and types of development have been catered for, including industrial development sites, hypermarkets and airports. Areas of up to 55 hectares can be covered with a single unit.Features• Long life efficient coalescer units.• Good access to all parts for desludging.• Nine different inlet/outlet orientations to suit site drainage lay-out.PerformanceThe Stormceptor tests at the hydraulics research establishment, HR Wallingford, achieved an average of 0.67mg/l, well within the 5mg/l required by the European Standard BS EN 858-1.The cost effective solution to light liquid separation, NSB 3-1000The high performance separators for maximum long term efficiencyInlet/outlet connections 110/160 PVCU socket/spigot 225/300 Quantum socket/spigot.

It can be simply lifted out for cleaning during routine maintenance.Introduction and operationThe SPEL Puraceptor models are designed for high performance and long service life between maintenance periods.The Puraceptor is available in two versions, single or two chamber, dependent upon the site application and requirements.An automatic closure device (ACD) is fitted to close off the separator when the contained oil exceeds the maximum oil storage volume.Why all SPEL class 1 separators perform best – even on heavily polluted sitesThe ‘HEART’ of the separation process is the robust and highly efficient coalescer unit or units. These strong stainless steel units incorporate robust high volume reticulated foam inserts. The inserts efficiently coalesce the finer globules of hydrocarbons for gravity separation and due to their large volume, last for long periods before requiring cleaning. Cleaning is then a simple operation using normal pressure water.PerformanceSPEL Puraceptors have been tested in accordance with the European Standard BS EN 858-1 and the results were substantially within the maximum hydrocarbon concentration in the outlet of 5mg/l. The average for all units tested was 1.22mg/l.SPEL Puraceptor® class 1 full retention separators – single and two chamber versions, NS 4-1000Oil to topOily water inCleaner water to second chamber Clean water outTo coalescer.

In order to facilitate easy withdrawal of coalescer units the SPEL tripod and hoist is recommended.Above: Lifting, locating and locking system with guide rail system.Right: The SPEL coalescer unit with lifting chain.Brackets fixed to the top and bottom of the coalescer unit simply engage the stainless steel guide rail fixed to the top of the stub access shaft. The coalescer unit is then lowered in the normal way, being guided at the correct angle into the conical base.Lifting chains are available for the larger coalescer units and where extension shafts are fitted.Extension guide rails can be incorporated into SPEL extension shafts to suit (preferably when ordered with the separator).SPEL coalescer unit lifting, locating and locking systemThe SPEL lifting, locating and locking system is manufactured in stainless steel and replaces the standard coalescer unit handle.The locating/locking handle ensures the coalescer unit is seated and locked in its correct position after maintenance.SPEL coalescer unitThe unit comprises a stainless steel holder with lifting handle and a foam insert. It is the essential part of the Class 1 separators.The highly efficient large volume reticulated foam insert facilitates the coalescing of the smaller oil globules and their separation by gravity to provide a discharge quality well within the requirements of the European standard.The high volume of the inserts safeguard against blockages due to silt and ensures a long life between servicing.The inserts are easily cleaned using normal pressure water and rarely require replacement.Optional extrasSPEL coalescer unit guide rail systemTo facilitate easy insertion of coalescer units, the SPEL guide rail system manufactured in stainless steel can be incorporated into SPEL Puraceptors and class 1 Stormceptors.SPEL coalescer unit; the ‘HEART’ of the separation process6SPEL Separators are moulded with general purpose polyester resins.

The tank must be handled with care to prevent accidental damage from impact or contact with sharp objects.Tanks should be lifted using slings, not chains or wire ropes. Do not drag tanks along the ground for any distance and avoid jarring or bumps. Do not lift with water in the tank.Health and safetyInstallation should be carried out by a competent contractor in accordance with Health & Safety at Work legislation and good building practice.A warning notice should be visible at the top of each access shaft – ‘danger, harmful fumes’ and ‘respirators must be worn in this tank’. Before entering persons must be qualified in accordance with ‘confined space’ requirements.Specifications. Site preliminaries7Models availableSPEL OMS-1 – To alarm for oil only and thus indicate a service is required.SPEL 2000 High Level/Oil – To alarm for oil (service required) and high level which could indicate the coalescer/s also require cleaning or the ACD (automatic closure device) has shut the ‘full retention’ type separator off.SPEL HLS – To indicate a high level situation (coalescers require cleaning or ACD has shut off) and high silt for warning the silt capacity has been reached and requires emptying.SPEL 2000 OS – To warn the oil and silt require removal.SPEL Solar S GSM – This is a solar powered alarm that will communicate an alarm to the user’s mobile phone or a central control system.HAZARDOUS AREA SAFE AREASPEL SeparatorControlunitSPEL automatic alarm/monitoring systemsThe SPEL automatic alarm/monitoring systems provide visual and audible warning when the level of the oil in the SPEL Separator reaches 90% of the storage volume under static liquid level conditions. This is a requirement of the Environment Agency’s Pollution Prevention Guidelines PPG3.The systems comprise a conductive ‘fail safe’ probe mounted in the main separation chamber which senses when the designed volume of light liquids has accumulated and sends a signal to the electronic control unit activating a red ‘empty now’ warning light and an audible alarm.OperationThe probe is freely suspended in the probe protection tube in the separator at the correct level. When the oil-layer or depth of hydrocarbons reaches the predetermined level, the top of the probe will be immersed in the oil, breaking the circuit and activating the alarm. It is a ‘fail-safe’ system providing complete assurance that it is operative. If a fault occurs it will be signalled immediately.MaintenanceWhen the separator is maintained you lift the probe out of the protection tube, wipe clean to prevent a false alarm and re-insert into the protection tube.TOP: SPEL Solar S GSM + BRIGHT: SPEL 2000 OS control unit, SET/DM3AL and SET/S2 sensors8SPEL vehicle wash silt trap SPEL Econoskim® System Above ground installationsSPEL vehicle wash silt traps model ST800/5 tonne and ST800/12 tonneWhichever type of vehicle washing installation, the SPEL vehicle wash silt trap is essential to solve this problem. Dirty water flows directly into the vehicle wash silt trap where the sludge and grit settle out prior to the water passing through the high level outlet to the drainage system.Moulded in glass reinforced plastic (GRP) it is easy to handle, robust and corrosion proof. The heavy duty, hot dipped galvanised gratings comply with slow moving wheel load bearing requirements of FACTA Class B gratings available in 5 or 12 tonnes.For ease of access and to empty the vehicle wash silt trap the grating is hinged and held open with an integral stay. Sludge can then be removed manually or by tanker.The SPEL Econoskim® light liquid skimming and separate containment systemReduces emptying costs by up to 90%SPEL Puraceptor separators are being specified for large railway depots, industrial and commercial sites, with the SPEL Econoskim light liquid skimming and separate containment system. This maintains the units in peak performance and dramatically reduces maintenance costs.Emptying is confined to removing the sludge accumulated in the relatively small primary chamber and the light liquid pollutants from the containment tank. This involves far less volume than would be the case with a conventional system and therefore less costly. In some situations the light liquids have a recovery value.The Econoskim system is available in manual or fully automatic form.UK Patent No.2355211.SPEL Separators for above ground installationsSPEL Separators are also designed and manufactured for above ground installations.
