Soil washing

Soil cleansing

These pollutants can enter from soil into the air and Running and underground water so cleaning the soil from this pollutants is necessary. Currently, different physical (such as heat), chemical (such as use of solvents) and biological methods are used to clean the soil, each of which has its own advantages and disadvantages. Meanwhile, the use of micro-organisms in cleaning the soil has a special place in different countries, and the important advantages of this method can be mentioned as cleaning in place, reducing a higher percentage of pollutants compared to physical and chemical methods, and less time. Microorganisms are able to break down various pollutant compounds and turn them into harmless compounds, so depending on the type of pollutant, one or a consortium of microorganisms can be used. By having a collection of different types of microorganisms isolated from polluted environments and optimizing them, the PGA Company is able to clean soil contaminated with different types of compounds. In this method, based on the type of pollutant, microorganisms are selected and multiplied and sprayed at the same time by mixing the soil. Based on the concentration of pollutants, the number and time between spraying varies.
