  • Soil Washing

    Introduction: Soil washing is a water-based process for scrubbing soils ex situ to remove contaminants. The process removes contaminants from soils in one of two ways: By dissolving or suspending them in the wash solution (which can be sustained by chemical manipulation of pH for a period of time). By concentrating them into a smaller volume of soil through particle size ...

  • Biotechnology of hydrocarbon bioremediation in soil washing slurry

    Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

  • Effect of OSE(II)-Enhanced Soil Washing(OESW) for TPH -Contaminated Soil Remediation

    The objectives of this study were to perform potentially suitable active agent that solubilize total petroleum hydrocarbon (TPH) present as contaminants and to evaluate the optimal range of process parameters that can increase the removal efficiency in OSE(II)-enhanced soil washing (OESW) pilot tests. Used experimental method for solubilisation of TPH by using OSE(II) was batch experiments. The ...

  • Bioremediation applied to high pH contaminated soil washing slurry

    BioFuture Ltd. in conjunction with General Smontaggi SpA have used applied environmental engineering and bioaugmentation to remediate hydrocarbon contaminated soil washing slurry. The soil washing slurry had been treated using lime to dry and stabilise it for transport to special landfill for disposal. The starting pH was 12.55 and it was successfully bioremediated so that it could be used as a ...

  • Soil Flushing

    Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

  • Titanium Scrap Metal Processing

    Background A world-class processor of titanium scrap had a wash system whose cleaning solution was becoming contaminated with both free floating unemulsified tramp oil and emulsified water soluble oil that was being washed off of titanium turnings. As the level of oil contamination increased over time in the wash solution, cleaning effectiveness diminished. The processor uses a metric, ...

  • Derwen construction commissions a new washing plant for aggregates

    Who’s involved? Derwen Construction and the Wales Environment Trust. Background. Derwen Construction was established in 1993 as a civil engineering company, however three years ago, when they began to find it difficult to find landfill sites for the inert waste generated on their sites, they decided to become self sufficient and set up a recycling plant, ...

  • Ivey-sol surfactant enhanced soil washing technology overview and project experience - Case Study

    lvey-sols soil washing is an ex-situ surfactant enhanced remediation (SERS) treatment method which removes hazardous substances from contaminated soils, solids, tank bottom sludge, drill cuttings, drilling muds, etc. The soil washing process (Photol) involves the introduction of the contaminated solids into a treatment chamber which contains an Ivey-sol2 formulation and water, at a specified ...

  • Titanium as an indicator of residual soil on arid-land plants

    Titanium (Ti) has been suggested as a soil contamination indicator for plant samples slated for trace element analysis because it is abundant in soil but not in plants. Based on results from our survey of regional soils and plants for cesium (Cs), we sought to confirm Ti as a valid soil contamination indicator reasoning that there are three sources of Ti associated with plant samples: (i) ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Contaminated soils and sludge treatment plant - Case Study

    Client: Ecosistem Group, Lamezia Terme (CZ) – Italy Challenge: to transform waste into product! The Client possesses a large plant for the treatment of products contaminated with hazardous substances and materials, recycling of recovered materials and disposal of non-recyclable waste, which is considered highly ...

  • Characterization and treatability of a contaminated soil from an oil exploration zone

    Abstract: A crude contaminated soil, arising from an oil production zone in Tabasco, Mexico was studied. A sample of about 40 kg was dried and screened through meshes 10-100. Total petroleum hydrocarbons and 6 metals (Cd, Cu, Cr, Ni, V and Zn) were determined to the different portions. For soil which passed mesh 10, six non-ionic, three anionic and one zwitterionic surfactant solutions ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • Treatment of soil eluate containing nitro aromatic compounds by adsorption on activated coke (AC)

    Soil washing is a kind of physical method to remove organic matters from contaminated soil. However, its eluate after washing may result in secondary pollution to the environment. In this study, activated coke (AC) was used to remove organic pollutants from contaminated soil eluate. The effect of temperature, initial chemical oxygen demand (COD) and AC dosage on COD removal efficiency was ...

  • Versatile Hot Water Pressure Washing Machines for Industrial Cleaning

    Hot water pressure washers are ideal dual purpose machines, as they can use hot water as well as non-heated water for cleaning different surfaces. Having this choice is important, because some applications do not require the additional cleaning power of hot water. Some surfaces may even become damaged by very high temperatures. On the other hand, the contractor will often come across cleaning ...
