Oil-contaminated soil groundwater automatic purification system: 3N injection method
A bioremediation method that allows for the purification of oil-contaminated soil while predicting the purification period.
The "3N Injection Method" involves injecting three types of N (nanobubble water, oil nano-decomposing agent, and nutrient salts) into the ground to purify the oil content in the soil and groundwater through the activation of in-situ oil-decomposing microorganisms. While utilizing the land and according to the budget, effective purification will be carried out with purification predictions based on the state of contamination, which can be completed within a year or over several years. 【Features】 ■ Purification can be carried out while the building remains operational. ■ Purification is possible according to the annual budget. ■ The system's parts are compact and lightweight, making transportation, installation, and system modifications easy. ■ The purification system can operate automatically using solar power even without an electrical supply. ■ The installation area for the purification system equipment is approximately 2m x 4m or less. *For more details, please refer to the PDF document or feel free to contact us. 【This product is provided by our group company, "Foundation Ground Consultants Co., Ltd."】

basic information
【Overview of 3N Injection Method and System】 ■Target for purification: Oil components ■Purification method: Bioremediation using indigenous oil-degrading microorganisms ■Purification period: 1 to 2 years (varies depending on oil concentration) ■Purification process: - Install pumping wells and injection wells to understand the oil concentration in soil and groundwater, as well as the direction and velocity of groundwater flow. - Conduct quinone analysis of the soil and perform purification predictions using the quinone profile method. - Generate fine bubbles in the pumped groundwater, and automatically inject site-generated water containing oil-degrading treatment and nutrients into the ground to activate oil-degrading microorganisms. - After several months, conduct a confirmation survey of the purification effect, and finally determine the completion of purification. *For more details, please refer to the PDF document or feel free to contact us.
