ERH treatable

contaminants

Solution

TRM offers the thermal remediation technique of Electrical Resistance Heating (ERH).

ERH uses the flow of alternating current electricity to heat soil and groundwater and

evaporate contaminants. Electric current is passed through a targeted soil volume

between subsurface electrodes.

The resistance to electrical flow causes the formation of heat and a rise in temperature,

approaching water boiling point.

Further energy causes a phase change and forms steam to remove volatile

contaminants

A safe, effective and proven technology in all lithologies and most contaminants

Economic when compared to lifecycle costs of alternative technologies

Fixed price remediation

Operates beneath buildings, in active facilities, and across public rights-of-ways

REMEDIATION TECHNOLOGIES: THERMAL

Thermal Remediation

Electrical Resistance Heating — a unique approach

TRM now offers ERH as a viable remediation technology

Practised in the Netherlands and the USA, this emerging technology is

ideal for sites with operational and time constraints

Capability Statement

Ex-Situ Bioremediation

Involves excavation, screening and

often pre-treatment

Soils may be formed into biopiles,

windrows or treatment beds

Specialist plant is used to de-compact

and aerate soils to maintain optimum

treatment conditions

Treated soils may be used as backfill

In-Situ Bioremediation

May be undertaken on active and

occupied sites, underneath buildings

and also for groundwater

Injection of nutrients and bio-support

media may be implemented with

aeration, and vapour extraction

Integrated systems allow the whole

volume of soil to be treated as a

bioreactor to degrade organic

contaminants

REMEDIATION TECHNOLOGIES: BIOREMEDIATION

Bioremediation

Bioremediation is an established technology that can be undertaken for a

range of organic contaminants

TRM undertake bioremediation projects for soil and groundwater

treatment

TRM routinely delivers successful bioremediation as ex-situ and in-situ

systems and in combination with other physical and chemical techniques

Soil Washing

Soil washing removes a range

of contaminants from granular

soils

High quality, clean material is

produced for reuse on site,

and disposal costs are

minimised

Physical Processing

Off-site disposal can be very

expens i ve. TRM cl eans

contaminated soils using

physical sorting and separation

processes including crushing

and screening to minimise

disposal costs, and maximise

recycling of clean backfill

material

Solidification and Stabilisation

Technology (SST)

SST uses specially designed

mixtures of cement and binders

to lock in contaminants

Good for difficult to treat

contaminants, sometimes as a

pre-treatment method

May result in engineered

material that is suitable to backfill

REMEDIATION TECHNOLOGIES: EX-SITU TREATMENTS

Ex-Situ Treatments

TRM undertakes a range of ex-situ treatment techniques

TRM offers soil washing, solidification and stabilisation technology (SST),

physical processing methods and traditional excavation and disposal

Capability Statement

Enhanced In-Situ Chemical Treatments

TRM undertakes in-situ treatments to

degrade a range of contaminants by

using chemical and biological

injection methods

Chemical oxidation or reduction can

be used for different contaminants, as

well as surfactant injection. Specialist

chemicals are delivered by injection

pumps to selected areas of geological

strata as required

Typically these methods are used to

augment other physical separation

and treatment techniques

Enhanced In-S i tu Physical

Treatments

Soil Vapour Extraction (SVE)

compounds in the unsaturated

zone by applying a negative

pressure through a network of

boreholes

Free product rem oval by

groundwater pumps in extraction

boreholes is routinely undertaken

and augmented with vapour

extraction and often total fluids

abstraction to form dual and

multi–phase extraction treatment

systems

Air sparging and stripping are

undertaken to reduce volatile

In-Situ Treatments

TRM undertakes a range of in-situ treatment techniques

TRM offers chemical injection methods, soil vapour extraction, dual and

Capability Statement

TRM owns and operates ATEX-rated remediation equipment for volatile atmospheres

and routinely conducts groundwater treatment projects for a range of clients.

Free and dissolved phase contaminants are treated by physical, chemical and

biological methods including carbon-separation pods, oil-water separators, vacuum

enhanced recovery, injection programmes, air stripping and catalytical oxidation

methods and bio-polishing techniques.
