Marsh:Marator oil separator – an innovative separator system that breaks the constraints of the current standards.

The Marator oil separator takes advantage of nanofiltration technology to produce discharge that is 50 times better than any current separator available on the market today; that is less than 0.1mg/ltr – the standard only requires less than 5mg/ltr for a ‘class 1 discharge’.

Testing was analysed for hydrocarbon content using infrared spectroscopy at GEOTAIX UMWELTTECHNOLOGIE GmbHA.

During the sampling period, five samples of 500ml were taken via the sampling point. The quality of discharge from the Marator exceeded the measureable level of the test equipment not to mention the current EN standard:

A Bypass Oil Separator is used in a ‘low risk’ environment where there is no requirement to provide full treatment for the flow: for example a car park where the risk of a significant spillage is small.

Designed and tested to BS EN858 parts 1&2, Marsh Hydroil bypass separators are manufactured from virgin unfilled resin offering exceptional durability, impact resistance and are guaranteed to be watertight and of uniform thickness. These combined properties ensure that the full range of separators stand up to the most rigorous conditions during their service life.

Internal working components, such as coalescing filters, weirs, oil skimmer plates, and their configurations offer the most modern and efficient oil/water separation capability available to the market today.

A wide choice of inlet and outlet positions are available on the units – detailed requirements should be provided at time of order (standard inlet and outlet positions will otherwise be fitted).

Typical applications

• Car parks
• Roadways
• Industrial estates
• SuDS

A full retention oil separator is used where there may be a ‘high risk’ of a significant fuel spillage, such as vehicle workshops

Designed and tested to BS EN858 parts 1&2, Marsh Hydroil full retention separators are manufactured from virgin unfilled resin offering exceptional durability, impact resistance and are guaranteed to be watertight and of uniform thickness.

Mitigation indices

As the world focuses on more green and environmentally friendly solutions, Marsh Industries has examined how effective their separators are when incorporating them into sustainable drainage schemes.

The company tested their full retention Hydroil separator range for total suspended solids and metal mitigation indices in line with industry-approved procedures at PIA, the notified test house in Aachen, Germany. This is in addition to an existing test procedure, whereby the Hydroil has already achieved EN858-1 certification for light liquid separators.

Combining these two test sets together and applying the simple index approach to proprietary/manufactured EN858 devices, the Hydroil separator range is able to achieve the following mitigation indices:

Hydrocarbons: 97.5%
Total Suspended Solids: 84.35%
Total Metal Reduction: 63.26%

The results will provide user confidence that the testing of this range is beyond reproach and cements these products as the complete surface water treatment solution for SuDS schemes.

Available in capacities from 2000-20,000 litres, the Marsh washdown oil separator range safely removes silt and debris from vehicle wash-down facilities.

These units are primarily used on car wash bays, pressure wash facilities or other cleaning facilities where the effluent must be discharged to the foul water drainage system.

It is a legal requirement to install a silt trap or wash-down separator on commercial sites, such as vehicle wash bays, where there is an environmental risk of contamination from dirt, brake dust, traffic film residue, cleaning agents, oil, etc. In all cases, you should contact your local building control or environmental agency for specific site requirements.

Easy access turrets for maintenance and servicing (Turret guards optional) are available. Variable invert depths and inlet/outlet configurations are also available ­­­to suit individual site conditions. Please contact Marsh Industries upon specification.

As with all Marsh products, the tank body is guaranteed for 25 years with a design life of 50 years, providing it is installed in accordance with the manufacturers installation instructions

An oil separator alarm monitors the level of liquid in oil separator units. An alarm signal is generated when there is an excessive level of oil, liquid or silt, or when the unit requires emptying.

An oil separator alarm is required on all separators to prevent hydrocarbons from entering the drainage system, and to ensure safe and economic operation of the unit.

Marsh Industries can supply various types of oil level, silt level and high level alarms, as well as bespoke options as required.

All alarms supplied by Marsh comply with EN858 parts 1&2, provide explosion protection and are ATEX approved.

For advice and guidance on choosing the right alarm for your site please contact Marsh Industries on +44 (0)1933 654582 or email separators@marshindustries.co.uk.

With capacities ranging from 830-3400 litres, Marsh silt traps provide effective storage of silt and debris from vehicle wash-down facilities.

Positioned ahead of an oil separator, the silt trap gathers and stores silt and sediment, and prevents it from entering the oil separator system.

The unit is supplied with a galvanised steel grating that provides exceptional structural integrity and allows for easy emptying.

As with all Marsh products, the tank body is guaranteed for 25 years with a design life of 50 years, providing it is installed in accordance with the manufacturers installation instructions
