Biological Treatment for contaminated soil, oily sludge and contaminated water.

E T C > Biological Treatment for contaminated soil, oily sludge and contaminated water.

ETC had been teaming with one of the world famous bioreactor design and operating companies, Petrozyme. The Petrozyme Process©, enables the onsite handling and treatment of hazardous oily wastes. The Petrozyme Process© is a reactor-based biological process for the degradation of oily sludge wastes from petroleum activities. The Petrozyme Process© utilizes advanced fermentation technology to degrade the major hydrocarbon components in petroleum.


A bioreactor is a vessel in which is carried out a chemical process which involves organisms or biochemically active substances derived from such organisms.

Under optimum conditions, the microorganisms or cells will reproduce at an astounding rate. The vessel’s environmental conditions like gas (i.e., air, oxygen, nitrogen, carbon dioxide) flow rates, temperature, pH and dissolved oxygen levels, and agitation speed need to be closely monitored and controlled. Optimal oxygen transfer is perhaps the most difficult task to accomplish.

The core technology involves high rate biodegradation of hydrocarbons in an aerated bio-reactor supplied with a proprietary nutrient blend and bacterial culture. Reactor design and process operating conditions promote the growth of highly active populations of bacteria that rapidly degrade the hydrocarbon sludge to H2O and CO2. Typical total petroleum hydrocarbon (TPH) concentrations input to the Petrozyme Process© are in the 10 – 30% range.

Land treatment (land farming)

Land treatment for petroleum wastes (land farming) has been used for several decades at locations throughout the world. Landfarming is an active process that accomplishes degradation of organic, immobilization of inorganic, and results in the transformation of hazardous constituents to less hazardous and non-hazardous constituents.

Through land farming, the organic materials in the waste are broken down. In many areas where the disposal of oily sludge in the sanitary landfill is unacceptable, the disposal of oily sludge by soil biodegradation is considered to be an acceptable method. ETC shall operate, and manage a landform facility that can solve the client waste problems economically and with cost-effective and realistic solutions.
