Contaminated soil treatment system
1. Soil Contamination
In recent years, companies have been producing more and more pollution, illegal dumping of industrial waste has increased. Also, heavy metal pollution in nature, such as soil pollution, has been increasing. So, as of February 2003, the Soil Pollution Treatment Law was created to protect the health of people. This law is about pollution levels, and lays out some ways to stop people getting harmed by pollution.
Urban Soil Contamination
Besides, public opinion on environmental problems, there are many reasons why people should start checking if their soil is contaminated when they trade or sell their land. Soil contamination affects the health of people, decreases the price of land and gives companies a bad reputation. This is where Sophia, can come in and suggest low-cost and appropriate treatment solutions.
Large-scale soil pollution from natural heavy metals during civil engineering projects
In Japan there are many mines, spas, and types of land where the chemical composition easily changes from one form to another, for different reasons. High levels of arsenic, lead and other heavy metals can be found in these areas and it is a concern that high levels of heavy metal might leak out into the surrounding areas when tunnels etc. are being made. Natural soil pollution directly affects the health of people, as well as fishing, agricultural, and tourism areas. The local industries also get a bad reputation because of the pollution. Therefore, we need to fully explain the methods used to remove or stabilize it, to the public, when construction work is happening, and tell everyone what effects it will have on the environment. As Sophia has been doing a lot of public work and research in universities, we use this experience to select the best treatment methods available that suit you and your problem or situation. |
Task example
・The soil is polluted with heavy metals.
・I want to resell a factory site and clean up the ground to prevent the price going down.
・Washing soil or changing it costs too much.
・If there is a way to stabilize the soil quickly without leakage, I want to know about it.
・Cleaning up boron and fluorine is difficult, but I want to deal with it.
・I would like to remove incinerator ash, dam's grout, or other types of pollution.
2. Sophia's Geochemical Stabilizing Technique
Stabilizing is a method to hold heavy metals inside minerals and stop leakage. Heavy metals exist in various forms in nature. The environment usually gets damaged when people extract resources. Changes in the environment cause heavy metals to become unstable and are then considered as a type of pollution. It is known that there are natural minerals in nature that can absorb and stabilize heavy metals. Sophia's geochemical stabilizing techniques make soil reusable using natural processes and nature itself, which has the lowest environmental impact. |
Characteristics
・Stabilize heavy metals by simply adding and mixing materials
・Despite the fact that boron and fluorine can be difficult to treat, this process completely stabilize them
・After stabilization the soil can be reused, as a filling material or on top of landfill.
・Heavy metals do not leak again, compared to the Cement Chelator System. →
The Soil Environment Center proved that soil treated with Sophia's materials, will be stabilized for a long time, using the Alkaline Acid Test.
