Air monitoring equipments for soil contamination monitoring

by Gradko International Ltd     based in Winchester, UNITED KINGDOM

Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.

Posi-Shell Coatings

by LSC Environmental Products, LLC     based in Apalachin, NEW YORK (USA)

Posi-Shell erosion control coatings are the perfect low-cost solution to protect and stabilize slopes. Our long-term coatings are spray-applied and allow engineers or operators to protect acres (hectares) of slope in a single day. The finished coating is durable and textured, reducing water energy across large areas. The final product eliminates erosion, siltation, and (as a result) expensive rework. The product can be designed to last for years and is easily tracked into slopes when intermediate protection is no longer necessary. Indeed, when integrated, Posi-Shell actually improves soil quality by conditioning it for future seeding. Posi-Shell’s simplicity and durability make it tremendously effective at controlling windblown dust, infiltration, or runoff associated with clean or contaminated stockpiles. Unlike cumbersome tarps or geo-membranes, Posi-Shell erosion control coatings are spray applied and do not require any ballast. Posi-Shell conforms and adheres to any topography and delivers 100% clean runoff. Stockpile loading or removal is accomplished by breaking into the coating where desired. Active areas may be left open or quickly resealed if required. Posi-Shell erosion control coatings are ideal for protecting expensive piles of salt, coal, or cement clinker; and are used extensively for containing hazardous or radioactive soils.

In-Situ Soil & Groundwater Remediation

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

The use of H2O2 to chemically oxidize the contaminants into mineralized products (CO2 , salts, and readily biodegradable organic fragments) offers a number of advantages over these current treatment methods. Benefits of Soil Decontamination by Chemical Oxidation: The reagent used (H2O2) is inexpensive, readily available, and has as its reaction products water and oxygen; The chemistry of the process (Fenton's Reagent) has been known for over 50 years and its applicability to a wide variety of contaminants is well documented; The process is easily applied and controlled; The treatment occurs rapidly, lasting from a few hours to a few weeks; The process produces no by-product wastestreams, and can be tuned for the degree of contaminant removal desired. This allows it to be used synergistically with other technologies such as biotreatment or soil washing.

GPR

by Geomorph Instruments     based in Piraeus, GREECE

GPR and EM play an integral part by providing a non-intrusive means of examining the subsurface for environmental hazards such as soil contamination, underground storage tanks and drums. GPR can delineate landfills and pathways for contaminant flow, as well as conduct hydrogeologic investigations such as water table mapping. We offer innovative technology to support site assessment needs.

High performance separation system for ethylene industry

by Pentair Filtration Solutions, LLC     based in Conroe, TEXAS (USA)

Fundamental building block chemical used in the production chain of polyethylene, PVC, styrene, ethylene glycol, vinyl acetate, linear ∂-olefins and a host of other chemical products. Eliminate hydrocarbons in Quench Water system, minimize fouling, provide greater system reliability, lower maintenance, lower energy costs. Quench water contains emulsified heavy aromatic hydrocarbon (SG = 0.975). Cracked hydrocarbons are extremely reactive. Polymerization leads to fouling of quench system, exchangers, dilution steam generator. Fouling reduces plant profitability and on-stream reliability.

High performance separation system for caustic treating industry

by Pentair Filtration Solutions, LLC     based in Conroe, TEXAS (USA)

The key aspects of a caustic treating system pertain to the degree of contact between the caustic and hydrocarbon to facilitate the mass transfer. Increasing the specific surface area of contact in a two phase system necessarily creates a tight emulsion. The product hydrocarbon often contains entrained caustic, which is not easily recovered by a simple water wash followed by a separator drum. The spent caustic is often regenerated with sour-naphtha stream that is used to extract the disulfide oils into the hydrocarbon phase.

High performance separation system for silicones industry

by Pentair Filtration Solutions, LLC     based in Conroe, TEXAS (USA)

Silicones are inert, synthetic compounds with a variety of forms and uses. Typically heat-resistant and rubber-like, they are used in sealants, adhesives, lubricants, medical applications, cookware, and insulation. Silicones are polymers that include silicon together with carbon, hydrogen, oxygen, and sometimes other chemical elements. Some common forms include silicone oil, silicone grease, silicone rubber, and silicone resin.

Contaminated Soils with Diesel Fuel and Heating Oils

by Sitelab Corporation     based in West Newbury, MASSACHUSETTS (USA)

Sitelab's UVF-3100D is used to test soil to help investigate and clean up sites contaminated by above ground or underground storage tanks (USTs). Soils can be analyzed for extended diesel range organics (EDRO) or extractable petroleum hydrocarbons (EPH). Results correlate well to confirmatory lab methods.

Hazardous waste treatment solutions for site remediation

by econ industries GmbH     based in Starnberg, GERMANY

The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

Mining Applications Testing TPH in Soil

by Sitelab Corporation     based in West Newbury, MASSACHUSETTS (USA)

Testing contaminated soils on-site for total petroleum hydrocarbons (TPH) is performed to monitor the progress of bioremediation activities at mining sites. Results only take a few minutes.

Enhanced anaerobic biodegradation for the soil and groundwater industry

by REGENESIS     based in San Clemente, CALIFORNIA (USA)

Enhanced anaerobic biodegradation is the practice of adding hydrogen (an electron donor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms performing anaerobic bioremediation (reductive dechlorination) on any anaerobically degradable compound or chlorinated contaminant. The most commonly targeted chlorinated groundwater contaminants are primarily used in industry as degreasing agents and include: Perchloroethylene (PCE), Trichloroethylene (TCE), Dichloroethylene (DCE), Vinyl Chloride (VC).

Other anaerobically degradable compounds include: carbon tetrachloride, chloroform, methylene chloride, certain pesticides/herbicides, perchlorate, nitrate, nitroaromatic explosives (TNT, RDX), dyes and chlorofluorocarbons (CFC’s).

Recycling and Composting

by EmiControls     based in Bolzano, ITALY

The treatment processes in recycling plants generate unpleasant and often harmful dust, which is a health hazard not only for nearby residents, but particularly for the employees. More and more legislation is being passed on dust control requiring such in the form of mobile units or fixed installations. In composting processes, the dust problem is compounded by unpleasant odors, which can be controlled effectively with specialized equipment. The same units are also used in biogas plants or for the removal and disposal of contaminated soil from industrial sites.
