Oil Removal Cartridges
Article: The Best Way to Dewater New Transformer Bunds
Green Rhino Oil Removal Cartridges are designed to remove hydrocarbon and sediment contaminants from groundwater accumulation in bunded areas or as part of a pollution prevention drainage solution on your site. Ideal for low risk sites with a flow rate up to 15L per minute.
With no mechanical parts and no power requirements, these reliable cartridges are significantly more cost-efficient than oil-discriminating pumps, interceptors and vacuum tankers.
Decontaminated water conforms to specifications for discharge to surface drains and into the environment (<5mg/litre of oil).
How does it work?
Each cartridge contains separate sediment and hydrocarbon filters.
Water enters the cartridge from the bund outflow and passes first through the sediment filter then the smart polymer hydrocarbon filter. Clean water is discharged from the end of the cartridge into the environment.
The sediment filter can be easily inspected and cleaned out.
The hydrocarbon filter contains our smart polymer which reacts with oils and fuels - converting them into solid rubber so they can’t escape. Only clean water passes through.
A wide range of hydrocarbons can be captured, including dielectric fluids, oil, diesel and used motor oils.
When all the polymer has been activated, flow is naturally blocked so no leakage can occur. This also means that the cartridges deliver a failsafe response when a catastrophic breach occurs. A build-up of water in the bund indicates that the filter needs replacing.
A fitting kit enables the filter to be removed, inspected and replaced without any leakage occurring.
