Biostimulation proposed by foundation ground consultants!
The "3N Injection Method" involves injecting three types of N (nano-bubble water, oil nano-decomposing agents, and nutrient salts) into the ground to purify the oil content in the soil and groundwater by activating in-situ oil-decomposing microorganisms. While utilizing the land and depending on the budget, effective purification will be carried out with a purification forecast that can be as quick as within one year or over several years, depending on the state of contamination. 【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 modification 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.

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 a few 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.
