Products Details
By utilizing our extensive resources, Astec has gained a leadership position in this industry and contributes as a major player because of our advanced and experienced engineering research and development.
Experience with material feed, conveyors, screens, dryers, fabric filters and scrubbers gives Astec the advantage in developing various remediation technologies.
Equipment designed especially for remediation includes equipment to process soil, sludge, bio-solids and other various contaminated materials. Air pollution control equipment has been developed as an integral part of these systems.
Contractors with the right equipment can comply with restrictions and even set new standards, while providing alternatives to waste generators for treatment, recycling and the recovering of contaminated materials.
Building equipment is not all we do. We provide permitting assistance and emissions calculations. We train your operators and help you with start up. In addition, we can also help you develop business plans and marketing strategies..
Contaminated soil is a common material treated with Astec Thermal Remediation equipment. The equipment needed to remediate soil varies with the type and amount of contamination. Required processing temperatures also vary. Most common contaminants are petroleum products, such as gasoline, diesel fuel, jet fuel, lubricating oils, fuel oils, coal tars and petroleum by-products. Typical processing plants for soil contaminated with these hydrocarbons are shown on this page. The process is described below.
To prepare contaminated materials for thermal treatment, they should be blended and screened. Minimizing feed inconsistencies, maximizing production rates.
Soil contaminated with hydrocarbons usually contains areas where contamination is greater than in others. Uniformity is essential for processing soil at a constant rate and to ensure conformance to specified cleanup levels. Blending mixes all ingredients uniformly and also evens out soil moisture. Blending is achieved by excavating soil from a relatively large area and mixing it before loading into a feeder bin. Blending can also be accomplished by using a two-bin feed system.
Contaminated soil often contains large rocks, metal refuse, clay lumps and other debris. Most debris is removed by a bar grizzly as the soil is loaded into a feeder bin. The soil goes from the bin through a clay shredder. It is then fed through a scalping screen, which catches and removes any remaining debris. After adequate pre-screening, blending and material preparation, the soil should have uniform moisture and hydrocarbon content and be free of debris. This ensures that thermal treatment will be thorough and efficient. An inclined conveyor then feeds and meters the material to the Primary Treatment Unit (PTU).
