❖Rhamnolipids have the properties that can bind and break down
oil, grease and other contaminants.
❖They also accelerate the natural decomposition process
Product used: yeast vegetable oil condensate with Rhamnolipids.
A multi wing stirring tank with volume of 10000l was mixed with
30/70 of the contaminated sand / soil with water and heated to
about 55 ° C, 30 ° C less than normal operating temperature.
Approximately 780l oil was contaminated in the sand.
The aim in this experiment was to reach a residual oil content
of only about 1%. In comparison
the best result with a polymer was a residual oil content of
1.8% with an oil content of 25% in the sand / soil mixture.
After the separation process the sand / soil fraction was taken
and handed over to an independent laboratory to determine the
residual oil
content. In addition, the laboratory also received an untreated
sample to determine the actual oil content.
Untreated : 35.8% oil and fat
Treated with Rhamnolipids yeast oil condensate: 0.42% oil and fat
