The SFT Series WRC-C1 is a unique water remedial system that can be
installed at sites that potentially pose the risk of discharging creosote
and hydrocarbon contaminated surface water into the environment,
such as electrical or telecom pole and rail sleeper storage facilities.
Designed and developed for the removal of hydrocarbons and other
contaminates typically found in creosote. The system utilises a number
of proprietary filters for removing polluting compounds found in EU
specification creosote, these contaminates include hydrocarbons,
phenols and cresols.
The WRC-C1 remedial chamber allows surface water to be processed
at up to 300 litres per minute and retains 35 litre of hydrocarbon while
removing contaminates to acceptable Environmental Agency levels
prior to discharge.

The system can be used to replace or to
complement oil water separation
systems where it is essential to prevent
pollutants from entering the environment.
The product has a versatile design and is
made specifically to operate and function
in industrial site environments.
The systems are built to operate to Class 1 oil water separator
guidelines. The system is a sealed unit that can be used in high risk
flood areas and can be either installed at new or retrofitted to existing
sites.
Environment Agency - Pollution Prevention Guidelines PPG3 April 2006
“Class 1 separators are designed to achieve a discharge concentration of
less than 5 mg/litre of oil under standard test conditions. These separators are
required for discharges to surface water drains and the water environment.”
A full retention separator is used where a regular threat exists of oil
contamination or a foreseeable risk of significant spillage. The SFT
Series WRC-C1 water remedial system has been designed to process
and treat the full flow of water that can be delivered by the drain
system. The ‘full flow’ is normally equivalent to the flow generated by
a rainfall intensity of 65mm/hour.
Pollutant Filtration
Unlike traditional oil water separators, the SFT WRC-C1 water remedial
system also targets emulsified, dilute and dissolved phased
hydrocarbons. Phenols and Creosols (the carcinogenic element of
creosote) are captured within carefully selected activated carbon
filters. Processed water is also passed through a biological chamber
where enzymes are utilised to break down dilute contaminates.
The system uses integral SFT HRF-80 hydrocarbon
and sediment cartridge filters which discharge
water to ≤0.1 ppm oil concentration.
Its design ensures that it is completely unaffected
by floods or flash flooding.
As part of the design evaluation we establish and consider the flow
rates of a potential spill delivered to the remedial system from the
drains and the oil storage requirements. Larger sites may require a
process holding chamber installing upstream of the remedial system
as an means of managing flow rate to optimise the efficiency and
size of the system.

Operational Process
The water remedial system is a weir design with water entry and exit
on opposite chamber wall sides.
Phased Filtration:
1. Chamber 1 contains brushes that start the removal process of
larger sediment particles as they pass through to the next
chamber.
2. Chamber 2 has a variety of foams configured with reducing pore
sizes to capture finer sediment particulate. A specialised pulp
based media contained within the casing is set above the foam
as an initial trap for contaminants such as creosote, hydrocarbon
and phenols.
3. Chamber 3 is a void of water to create a head pressure for the
filters located in the following two chambers.
4. Chamber 4 contains two HRC-80 filters that capture and
encapsulate hydrocarbon liquids.
5. Chamber 5 contains two activated carbon filters delivering an
even finer level to remove any dissolve phase hydrocarbons and
additional contaminants, such as Phenolic compounds.
6. Chamber 6 has a bioremediation block (kept solid by natural
waxes) containing micro-organisms and other ingredients,
designed to be suspended in wastewater contaminated with
hydrocarbons and 1” PVC tubes to encourage and facilitate
growth of algae to further assist in the reduction of potential trace
elements of pollution.
