Klargester Washdown Separators

INTRODUCTION
Separators serving wash-down areas such as car wash and other cleansing facilities must discharge directly into a foul drain, which feeds to a municipal treatment facility.
Such wash down facilities must not be allowed to discharge directly into either surface water or any oil/water separator discharging into a surface water as they utilise emulsifiers, soaps and detergents, which can dissolve and disperse the oils and upset the separation process.
Silt separators can be used as a supplementary unit to remove additional silt before other Separators or treatment units. If emulsifiers are present the discharge must not be allowed to enter a NS class 1 or class 2 unit.

APPLICATIONS
These units can be used to serve vehicle wash down areas and car wash facilities, although it should be noted that the prime function of such separators is for the removal of silt.
Typical locations using wash down separators are; -
Car wash, tool hire depots, truck cleansing, construction compounds cleansing points.
Locations requiring silt separators are; - Highly silted sites where NS separators are used, i.e. works constructions sites and temporary work compounds.

OPERATION
As contaminated water passes through the separation chamber, it is retained long enough to allow immiscible hydrocarbon pollutants, such as oils and petrol to accumulate on the surface of the water and settleable solids to sink to the bottom of the unit. Our design uses a maximum of 6 minutes retention time, at the flow rate given. The separator water is able to discharge safely without the risk of oil pollution to the municipal plant. It is generally accepted that greatest separation efficiency for oil is gained by using a single chamber separator as the pollutants have more time to separate.
The nature of the silt varies depending on either the ground or surface receiving the flow. These aspects should be considered when selecting the size of the unit in relation to the flow being treated.

CONSTRUCTION
Klargester oil/water separators are manufactured from durable, rot and corrosion proof glass reinforced polyester combining lightweight with outstanding strength. The units are delivered complete with inlet and outlet pipework as well as factory fitted access shafts to ensure quick and easy installation on site.

INSTALLATION
The unit should be installed on a suitable concrete base slab and surrounded with a concrete backfill.
If the separator is to be installed within a trafficked area a suitable cover slab must be designed to ensure that superimposed loads are not transmitted to the top or sidewalls of the unit.
Separators should be vented in accordance with
BS8301:1985:Building Drainage or Health and Safety
Guidance Note HS(G)41 for filling stations subject to Local Authority requirements.
Detailed installation guidelines are provided with the unit and are available separately on request.
The unit retains mainly silt which collects within the separator. It should be removed periodically to ensure that maximum effectiveness of the unit is maintained. The amounts of silt collected varies in relation to the source and use and maintenance intervals should take these factors into account.
Oil may also accumulate, if there are no emulsifiers and should be periodically removed. In the event of a major oil spillage the separator should be emptied immediately.
QUALITY
Klargester separators are widely used and specified by
Local Authorities, National Environmental Regulatory bodies and Licensing Authorities, including the London Fire & Civil Defence Authority.
All Klargester products are manufactured under BS EN ISO 9002 Quality Management System accreditation.

PRODUCT SELECTION
To select the correct separator for your application turn to the table overleaf or alternatively consult our Technical

If a Nominal size Full Retention or Bypass Class 1 or Class 2 unit is required, please see alternative data sheets.
Klargester have fully trained technical representatives operating throughout the UK who can offer on-site advice on request.

The units above all include a single chamber, (W1) but on request, we may be able to provide with 2 or 3 chambers. If you require larger units, these are also available. Please contact us to discuss your specific application
Invert depths (E) can be supplied in additional increments of 500mm from the minimum stated above.
Please indicate the inlet drain invert required when specifying units. Maximum 2.0 m.

To purchase or specify the Klargester separator you require, the following information is needed.

• The number of chambers and type of separator.
Prefix Reference (see table) with:
• W1 – If you require a single chamber oil/water separator
• W2 – If you require a 2 chamber oil/water separator
(1200 litre not available)
• W3 – If you require a 3 chamber oil/water separator
(1200 litre not available)
• The capacity of the separator in litres (see table),
• Drain inlet invert depth
• Inlet & outlet Pipework size if not the standard 160 mm PVCu

Note: We will assume that you require the standard unit unless you have specified differently. Additional charges may apply to alternate specifications
Non-standard inlet/outlet pipe sizes and reduced falls across the unit may be provided but please note we do not alter internal pipework dimensions. Please contact the Technical Sales Department for advice and to discuss your requirements available.
