Case Studies
Sampling across the pond establishes stratification, solids loading and working volume before any plant is mobilised.
Plant is transported to site and set up without permanent works, so the pond can be worked where it lies.
A horizontal decanter parts oil, water and solids in one continuous operation while extraction continues.
Recovered oil is purified for resale, water is treated to the site discharge limit and solids leave reduced in volume and mass.
Oversize material and debris are taken out ahead of the wash stage so the circuit runs without obstruction.
The wash stage releases hydrocarbon bound to the soil particles, which allows the mineral fraction to be recovered rather than disposed of.
Treated wash water returns to the wash stage, so fresh water demand is limited to make up rather than full throughput.
Treated soil is checked against the remediation target before it is placed back.
The tank is taken out of service, drained and made safe for entry before any cleaning begins.
Deposits are fluidised so they can be pumped out rather than dug out, which keeps the work continuous.
Sludge is separated into oil, water and solids as it comes, shortening the period the tank stays out of service.
Internals are cleaned to the standard required for statutory inspection and recovered oil is returned.
