Double-walled storage tank for storing landfill leachate

Project: Deponie GmbH Altmarkkreis Salzwedel – Thermally insulated leachate tanks

Double-walled water storage tank (KTD-FA-30-B) for Storage of landfill leachate with special inner coating, which is designed for the storage of water. The tank is completely thermally insulated and has an internal tank heater The electric tank heater is used to keep the medium frost-free. The entire tank piping is made of Stainless Steel On the tank roof is the Vacuum leak detector which gives an alarm if the inner or outer tank wall has a leak.

What are leachate landfill tanks and what are they used for?

Leachate landfill tanks are special containers used in landfills to collect and temporarily store leachate. Leachate is created when rain or meltwater seeps through a landfill and absorbs pollutants from the waste. This contaminated water can contain heavy metals, organic pollutants, or chemical compounds that are hazardous to the environment and human health.

To prevent these pollutants from entering the groundwater or nearby waters, the Leachate collected via a drainage system and fed into thermally insulated landfill tanks. From there, it can then be professionally cleaned or disposed of. Leachate tanks are an important component of environmental protection and legal requirements for landfill operations.

How is contaminated soil cleaned?

When soil is contaminated with pollutants such as oil, heavy metals, pesticides, or industrial chemicals, it is referred to as contaminated soil. Such soils can pose a threat to humans, animals, and the environment. Various soil remediation methods are available to eliminate these contaminations:

Excavation and disposal
The contaminated soil is excavated and transported to a special landfill. This is the fastest, but often also the most expensive, solution.
Soil Washing
This involves treating the soil with water and, if necessary, cleaning additives to remove pollutants. The solid components can then be reused.
Biological processes (bioremediation)
Microorganisms are used to degrade organic pollutants such as oil or solvents in the soil. This process is particularly environmentally friendly, but it takes time.
Thermal treatment
The soil is heated to evaporate volatile pollutants. The vapors are then filtered or incinerated.
Chemical oxidation
Soil pollutants are chemically broken down by adding oxidizing agents. This is used, for example, in the case of contaminated sites containing industrial chemicals.

The choice of method depends on the type and concentration of pollutants as well as on local conditions.
