Sludge Remediation at Caltex Oil Refinery, Australia

Oil Sludge Remediation

S-200 Oilgone was invited to remediate a test batch of 500 cubic metres of oil sludge taken from the bottom of a large oil silo in the Kurnell Caltex refinery, NSW.  The purpose was to trial the effectiveness of S-200 Oil Gone.

The sludge comprised contaminated soil from tank sediment, soil from around leaky pipes.

The average TPH loading of the 500 cubic metres is 36,000 ppm.

S-200 Oilgone is set a target of getting the TPH level to below 10,000 PPM

The Process for Treating Oil Sludge Through Bioremediation

Oil sludge has by its nature has a thick gelatinous consistency. In order for S-200 Oilgone® to bioremediate the sludge, it was important to allow oxygen to get to as much of the surface of the sludge as possible.

The sludge was mixed with loose straw, and then laid out in furrow form on a piece of ground near the refinery. The surface of the furrows was sprayed thoroughly with S-200 Oilgone®. The product bonds immediately with the hydrocarbons. 

S-200 Oilgone® is a nutrient additive. It provides a food source for locally occurring bacteria. These bacteria break down hydrocarbons in nature. However, when they feed on the nitrogen and phosphorous cores of the S-200 Oilgone®, they multiply much more quickly and create enzymes at a vastly accelerated rate. It is the enzymes that break down the hydrocarbons into carbon dioxide and water.

When S-200 Oilgone® is sprayed onto the sludge, it encapsulates the oil within its matrix. This has the impact of rendering the hydrocarbon inert and non-combustible.

Local occurring bacteria feast on the oil in an accelerated state, turning the oil into carbon dioxide and water. Then the bacteria eat the matrix itself and return unchanged to the local environment. There is no residue. Nothing to clean-up.

Test samples at 12 weeks indicted that S-200 Oilgone® had halved the hydrocarbon loading to 18,000 PPM.
 
At 20 weeks the TPH levels were at 12,000 and under the threshold of 10,000ppm within the 25 week target period.
