Soil Remediation for Oil (On-Site Technology)

• On-site soil washing

– The separation of treated anddense soil division by washing andclassification

– Washing can combine toextraction by the solvent andcollection by the flotation todevelop an efficiency of treatment.

• Land farming

– Bioremediation providing somenutritious materials and oxygenfor contaminated soil

42

Soil Remediation for Oil (In-Situ Technology)

• Injection

– Collection by pumping for oildissolved into ground water bythe injection of agent

– Oxidation composition byinjecting oxidative agent(Fenton reaction) or microbabble with ozone into theground water.

• Pumping and Treatment– Pumping up the ground water

and treatment of waste water43

A Case Study ： Land Farming

• We have performed the largest of treatment(80,000m3) for the soil contaminated with oil inJapan

• Contaminated soil is cleaned up to 1 to 3 months perone batch that is 200 ton.

• The heating treatment on site is applied to the highconcentration soil 44

A Case Study ：Injection (Oxidation Agent)

• This targets for the soil and theground water contaminated with thegas oil and kerosene in aquifer.

• We can Inject some agent (oxidativeagent or micro babble with ozone)into the soil in the case of lowcontamination.

• If the soil is high concentration, wecan mix agent with excavated soil onthe ground.

• Capable to decrease highconcentration up to less than1,000ppm
