Compliant fuel and oil separators from Kingspan Klargester

All manner of projects, both large and small, are required to maintain compliance with all environmental rules and regulations concerning property drainage. As an aspect of compliance, it is essential that the appropriate separators are deployed in order to meet or exceed the drainage demand but to also comply with the ongoing project demands such as cost and time. Kingspan Klargester offers a wide range of fully compliant Fuel and Oil Separators that meet environmental regulations and when combined with our experienced product experts, we can help select the right solution that provides value for you and your project.

Separator Requirements

The determination for use of a fuel and oil separator is based on the specific application of the property and not necessarily on size. Combined guidelines from the Environment Agency of England and Wales, The Scottish Environmental Protection Agency and the Environment and Heritage Service of Northern Ireland specify when fuel and oil separators are required. These are:

• Car Parks, for more than 50 vehicles or 800m2.
• Car Parks of any size in a sensitive environment.
• Any location where good transport is parked or maneuvered.
• Maintenance areas.
• Roads or Motorways.
• Sites where oil is used or stored.
• Refueling facilities.
• Any location at risk of contamination from oil or fuel.

Kingspan Klargester Fuel and Oil Separator Types

There are three types of Kingspan Klargester Fuel and Oil Separators for consideration. The first type is the full retention separator that is designed to manage the complete flow of drainage from the site or a flow rate of 65mm/hr, under standard conditions. The second type are Bypass Separators and these manage a flow rate up to 6.5mm/hr and if the flow exceeds this limit, the flow bypasses the separator system. The last type of separator is the Forecourt Separator. This type of separator is designed for installation in petrol filing station forecourts and similar applications. Forecourt separators can contain a spillage up to 7,600L.

Getting The Right Separator

Naturally, to provide the optimal separator, some factors require consideration. Our separator designs are based on non-impeded flows from external pipework, therefore, the factors to be considered are;

• Calculated flow rate for the area drained.
• The necessary discharge standard.
• Drain invert inlet depth
• All necessary pipework, type, size, and orientation.

Kingspan Klargester has a highly specialized team of experts that can assist you in procuring the right fuel and oil separator for your project. We also offer a free site inspection and analysis that can further assist you in selecting the right separator, if needed. Our team of site specialists and product experts have generations of combined experience in all sizes of projects.

Meeting High Standards

All Kingspan Klargester Fuel and Oil Separators correspond to British and European standards as set forth in EN 858-1 and 858-2. In fact, Kingspan Klargester was the first to be certified to EN 858-1 for a range of separators.

The features of Kingspan Klargester Separators are:

• Lightweight
• Easily installed
• Have fitted inlet/outlet connections
• Have Vent points and necks
• Include slit storage volume

In addition to these features, depending on the type and model, they can also include alarm systems, extended access shafts, ground level maintenance, and appropriate covers.

Bypass Separators

Bypass separators fully treat all flows generated by rainfall rates of up to 6.5mm/hr. This covers over 99% of all rainfall events. Flows above this rate are allowed to bypass the separator. These separators are used when it is considered an acceptable risk not to provide full treatment for high flows, for example where the risk of a large spillage and heavy rainfall occurring at the same time is small.

Surface water drains normally discharge to a watercourse or indirectly into underground waters (groundwater) via a soakaway. Contamination of surface water by oil, chemicals or suspended solids can cause these discharges to have a serious impact on the receiving water.

The Environment Regulators, Environment Agency, England and Wales, SEPA, Scottish Environmental Protection Agency in Scotland and Department of Environment & Heritage in Northern Ireland, have published guidance on surface water disposal, which offers a range of means of dealing with pollution both at source and at the point of discharge from site (so called ‘end of pipe’ treatment). These techniques are known as ‘Sustainable Drainage Systems’ (SuDS).

Where run-off is draining from relatively low risk areas such as car-parks and non-operational areas, a source control approach, such as permeable surfaces or infiltration trenches, may offer a suitable means of treatment, removing the need for a separator.

Oil separators are installed on surface water drainage systems to protect receiving waters from pollution by oil, which may be present due to minor leaks from vehicles and plant, from accidental spillage.

Effluent from industrial processes and vehicle washing should normally be discharged to the foul sewer (subject to the approval of the sewerage undertaker) for further treatment at a municipal treatment works.

Separator Standards and Types

A British (and European) standard (BS EN 858-1 and 858-2) for the design and use of prefabricated oil separators has been adopted. New prefabricated separators should comply with the standard.

Separator Classes

The standard refers to two ‘classes’ of separator, based on performance under standard test conditions.

Class I

Designed to achieve a concentration of less than 5mg/l of oil under standard test conditions, should be used when the separator is required to remove very small oil droplets.

Class II

Designed to achieve a concentration of less than 100mg/l oil under standard test conditions and are suitable for dealing with discharges where a lower quality requirement applies (for example where the effluent passes to foul sewer).

Both classes can be produced as full retention or bypass separators. The oil concentration limits of 5 mg/l and 100 mg/l are only applicable under standard test conditions. It should not be expected that separators will comply with these limits when operating under field conditions.

Clereflo Bypass Separator

The CNSB3S/21 is suitable for an area of up to 1667

Class 1 inc Silt trap

Bypass separators fully treat all flows generated by rainfall rates of up to 6.5mm/hr. These separators are used when it is considered an acceptable risk not to provide full treatment for high flows, for example where only small spillages occur and the risk of spillage is small such as on short stay car parks.

Process & performance

The Conder range of bypass separators is designed to treat all of the flow up to the designed nominal size. Any flow in excess of the nominal size is allowed to bypass the separation chamber thus keeping the separated and trapped oil safe. During the early part of a rain storm which is a time of high oil contamination, all of the contaminated water flow passes through a sediment collection chamber and enters the separation chamber through a patented oil skimming and filter device. This ensures that all of the oil proceeds to the separation chamber where it is separated to the Class 1 standard of 5mg/l and safely trapped. As the rain storm builds up to its maximum and the level of oil contamination reduces significantly, the nominal size flow continues to pass through the separation chamber and any excess flow of virtually clean water is allowed to bypass directly to the outlet.

Application areas:

• Car parks
• Roadways and major trunk roads
• Light industrial and goods yards
• Discharge to sensitive environment

Dimesnisons

• Length - 1.4m
• Dia - 1m
• Height - 2.2m
• Access - 750mm
• Base to inlet - 1.7m
• Base to outlet - 1.6m

Bypass Separators

Bypass Separators treat all flows which are generated by rainfall rates of up to 6.5mm/hr. This in turn means it covers over 99% of all rainfall.
Flows which are above this rate are allowed to bypass the separator. These separators are used when it is believed there is an acceptable risk not to provide full treatment for high flows. This can be explained where there is low possibility of heavy rainfall and a large spillage occur at the same time.

Surface water drains normal discharge indirectly into underground waters or to a watercourse via a soakaway. Sometimes chemicals, suspended solids and oil can contaminate the surface water affecting the discharges. This can have a serious impact on the receiving water.

There are regulations put in place and agencies i.e the Environment Agency who have published guidance on surface water disposal. These offer a range of methods of dealing with pollution both at the source and the point of discharge from site. This is called end of pipe treatment.

Sometimes there are methods in which you may not need a bypass separator. When run-off is draining from car parks and non operational areas these are classed as low risk areas. Therefore a source control approach such as an infiltration trench or permeable surfaces. This maybe a suitable means of treatment.

You can also install oil separators on surface water drainage systems. This protects the receiving water from oil pollutants which can be present due to accidental spillage or minor leaks from vehicles.

There are 2 standard types of bypass separators.
Class 1 - which is suitable for removing small droplets of oil
Class 2 - Which are suitable for dealing with discharge where a lower quality requirement applies. For example where the effluent passes to foul sewer.
