Environment & Soil Treatment

From Contamination To Conservation, Reviving Soil For A Better Future!

Our soil is the foundation of life, nurturing the growth of crops and sustaining ecosystems. However, decades of pollution, chemical use, and unsustainable practices have left our soils contaminated and depleted.
Soil remediation is the key to restoring polluted or contaminated land, ensuring a healthier environment and a brighter future for generations to come. By employing effective techniques, we can revitalize soil and transform it into a valuable resource once again.

Industrial Pollution of Soil.

A Growing Concern

Soils, the life-sustaining foundation of our planet’s ecosystems, are increasingly falling victim to degradation and pollution. Industrial activities contribute significantly to the contamination of soil, introducing harmful substances that can have far-reaching consequences.
One of the major culprits behind soil pollution is the presence of heavy metals, such as lead and arsenic. These toxic elements find their way into the soil through various industrial processes, including mining, manufacturing, and improper disposal of waste. Organic compounds like hydrocarbons and methane, stemming from industrial and agricultural activities, further exacerbate the problem.
Soil pollution caused by petroleum is a significant environmental concern with far-reaching consequences. Petroleum products, such as gasoline and oil, contain toxic chemicals that can contaminate soil through leaks, spills, and improper disposal. These pollutants can persist in the soil for years, affecting plant growth, disrupting ecosystems, and posing health risks to humans and wildlife. Petroleum pollutants can seep into groundwater, further exacerbating the problem. Effective prevention measures, such as proper storage and handling of petroleum products, as well as prompt clean-up and remediation efforts, are essential to mitigate soil pollution.
The consequences of polluted soils are multifaceted and potentially devastating. Groundwater and surface water resources are particularly vulnerable to contamination when polluted soils.
Several technologies are available to address soil pollution. One effective approach is “SOIL WASHING“, which involves removing pollutants from the soil through physical and chemical processes. Soil washing employs techniques like leaching, solvent extraction, and soil flushing to separate contaminants from the soil particles, reducing their concentration.
Soil washing is a highly effective method of remediation for contaminated soils. It involves separating the valuable components of the soil from the pollutants through a physical separation process. This multi-stage technique aims to reclaim and cleanse “dirty” soils by permanently separating them from the contaminating elements.
We specialize in providing soil washing systems for the treatment and remediation of various types of soil contamination, such as heavy metals, hydrocarbons, pesticides (including mono-aromatic and poly-aromatic hydrocarbons), as well as other toxic substances like cyanide, TNT, and PCBs. With our extensive expertise and knowledge, we have developed a high level of proficiency in constructing soil washing systems. This experience enables us to build large-scale soil washing plants that cater to diverse sectors. Our comprehensive solutions are designed to address specific contamination types and ensure the suitability of the recovered soil for its intended future use.

Contaminated Soils

Treatment System

We provide advanced treatment facility specializes in handling hazardous materials and contaminated soil and sludge. It provides a comprehensive solution that involves recycling recovered materials and environmentally responsible disposal of non-recyclable waste. The facility is equipped with cutting-edge soil washing technology, which physically separates contaminants from soil, inert materials, sand, and gravel. This process enables the recovery and reuse of these materials, promoting a more sustainable and efficient resource utilization.
The plant takes advantage of a specific washing protocol that applies a synergetic combination of water, additives and reagents in the physical washing of inert materials. Hence, the soils undergo a series of treatments before their final degree of cleanliness is achieved.
Used washing solution is chemically treated and reintroduced into the production cycle.

Description of the treatment process

Each plant is customized based on the specific land characteristics to provide the best technical-economic solution. We designs by partner company the plants using data from laboratory tests conducted on soil samples.
When a soil has a significant inert fraction, the soil washing technique can be employed. This involves wet separation to remove the contaminated fraction from the larger, non-polluted fraction.
The treatment process generally involves the following steps:
Excavation and possible storage of the soil in a designated area.
Coarse screening of the soil to separate materials by size.
Washing the material in the plant using chemical solutions to enhance contaminant removal
Separation of sand and gravel from the washing sludge, which consists of water with contaminated silts and clays.
Analysis to verify the presence of pollutants in the solid part. If positive, the aggregates leave the washing cycle; otherwise, they undergo another cycle.
The washing water can be reused for multiple cycles and is ultimately purified and discharged into the sewer.
Soil and contaminated soil treatment projects using soil washing require an integrated approach that combines civil engineering, hydrogeology, and environmental technology.
Key outcomes of this process include recovering 90% of aggregates from the soil, with only 10% of the input material going to landfill. The soil recovery rate typically ranges from 60-70% by weight, although it may vary depending on the size distribution.
