Ozone soil remediation refers to a method of soil decontamination that targets a wide range of pollutants such as petroleum hydrocarbons, solvents, and pesticides. The technique involves injecting ozone gas into the soil, which acts as a potent oxidant and breaks down the contaminants, converting them into less toxic substances. This eco-friendly and cost-effective method has been implemented in various contaminated sites globally, offering a reliable and efficient solution for soil remediation.
Ozone has been increasingly utilized to remediate sites contaminated by a diverse range of soil pollutants. It can effectively target both biodegradable compounds that decay slowly over time and non-biodegradable ones that cannot be easily degraded when attached to soil particles. Ozone is particularly advantageous over traditional remediation methods because it does not require extensive soil excavation, which is often infeasible due to the presence of underground infrastructure such as water pipes and utility lines. Ozone treatment is simple to implement and has proven to reduce contaminants by up to 99%, making it a remarkable solution.
What Containments can be Destroyed by Ozone
Ozone soil remediation can treat a variety of contaminants, including:
- BTEX (benzene, toluene, ethylbenzene and xylene)
- Chlorinated solvents
- Petroleum hydrocarbons
- Solvents such as MTBE and TCE
Benefits of Using Ozone Soil Remediation
- Apart from the low capital equipment costs, the implementation of ozone also incurs minimal operating costs.
- The installation process will cause minimal disturbance to the site.
- Ozone provides in-situ destruction of specific components.
- The reduction of contaminant mass and concentration in soil and water occurs rapidly, and significant improvements may be noticeable within a few weeks.
- The reaction is clean and does not produce any hazardous by-products.
- The use of microbubbles in ozone soil remediation helps to extract volatile organic compounds (VOCs) from soil pores and groundwater. This approach reduces the oxidative demand on soil, which is usually associated with liquid oxidants.
Site Assessment: During the ozone soil remediation process, a comprehensive site assessment is carried out to detect the types of pollutants present in the soil and their concentration levels. The collected data is then analyzed to determine the suitable ozone injection rate and duration necessary for the soil remediation process.
Soil Preparation: It involves drilling boreholes or injecting pipes into the soil, which are used for ozone injection. Ozone is then injected into the soil through these holes or pipes.
Ozone Injection: The injection of ozone gas into the soil is performed with specialized equipment that pressurizes and pumps the gas. The high-pressure ozone gas reacts with the contaminants, leading to their oxidation and breakdown into less harmful substances.
After the ozone injection process, a post-treatment validation is carried out to verify that the contaminants have been effectively remediated to meet the acceptable levels.
