Gippsland Water And Collex Attend Wellington Shire Council Meeting

Gippsland Water and Collex Pty Ltd attended the Wellington Shire Council meeting on Tuesday night to present information on treatment technologies proposed for use during Stage Three of the Soil and Organic Recycling Facility (SORF) at Dutson Downs.

An application for a Works Approval for Stages One and Two of the construction of this facility was submitted to EPA on 20 July 2005 and Gippsland Water now intends to lodge a further application for Stage Three.

Stage Three proposes the treatment of contaminated soil that cannot be composted. These soil will only be accepted and treated on an as-needs basis. The treatment processes proposed will be brought to the facility specifically for this purpose, and will be removed following completion of the treatment process.

Collex Pty Ltd, Gippsland Water’s technology partner, will implement the treatment technologies proposed for this stage of the works, including solvent extraction and indirect thermal desorption.

A spokesperson from Collex provided an outline of the treatment technologies proposed:

Indirect thermal desorption involves placing the soil in a large closed vessel. The soil is heated without exposure to a direct flame, much like an oven. Once heated, the contaminants are vapourised and the gases are then extracted from the vessel. This gas is allowed to cool, where it returns to a liquid or solid form. The contaminants are captured and transported to a facility off-site for further treatment or disposal. The clean soil is then available for reuse following appropriate testing to confirm that the contaminants have been removed.

The solvent extraction process involves placing the soil in a series of closed vessels, similar to skip bins. The vessels are filled with an alcohol based solvent that flows through the soil. The contaminants present in the soil dissolve into the solvent. This solvent is treated to remove the contaminants which are transported to a facility off-site. The solvent is then available for reuse in the treatment process. The clean soil is available for reuse, following appropriate testing to confirm that contaminants have been removed.

A spokesperson from Collex said "The proposed treatment technologies have been used widely in the United States, Canada and Japan for over ten years. Collex has carefully selected these two treatment technologies, based on their proven efficiencies in removing contaminants with minimal environmental impact. The enclosed nature of these systems ensures the effective control of emissions to air, water and land."

Gippsland Water CEO, John Mitchell, said "Having Collex as our technology partner on this project greatly strengthens Gippsland Water’s capability to ensure that the soil and organic recycling is carried out using the best technologies available world wide.

"If our region does not have the technical capability to safely deal with contaminated soil, then these soils will be merely left in the ground. In this way we are not dealing with the environmental problems that exist.

"For this reason Gippsland Water is committed to providing this technology to responsibly treat contaminated soil in an environmentally sound and effective manner. This facility will provide a sustainable solution to the management of waste and the remediation of contaminated sites existing within our communities.
