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...
Water is the most valuable resource on earth...…and it should be treated as such. ProMinent specialises in reliable solutions for water treatment and disinfection that effectively eliminate bacteria, viruses and harmful substances.
Chromium, Zinc, Copper, Lead, Cadmium, Mercury and Arsenic are among the most common metal contaminants found on clean-up sites. REMOTOX® precipitates these highly soluble metals as less soluble, less toxic metal sulfides. Hexavalent chromium is reduced to trivalent state and precipitated as chromium hydroxide in a one-step process.
Nanoremediation represents a modern method of treatment of environment polluted by chlorinated hydrocarbons, heavy metals, radionuclides and other contaminants. This technology started to be used tentatively in USA and it already takes place on various sites around the world at present.
Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for...
In Situ Thermal Remediation (ISTR) Beneath and Around Existing Buildings and Infrastructure; In Situ Thermal Remediation (ISTR) technologies, including In Situ Thermal Desorption (ISTD), the Electro-Thermal Dynamic Stripping Process (ET-DSP™), which is an advanced form of electrical resistance heating, and Steam Enhanced Extraction (SEE) have been demonstrated effective in treating source zones with limited access and those adjacent to or beneath buildings and other infrastructure.
ISTD (In Situ Thermal Desorption) = no excavation needed. It often occurs that real estate companies are confronted with contaminated soil in a property, creating a legal and financial problem for transfer of ownership.
BioSolve Pinkwater is used for cleaning/decontaminating tools and equipment at remediation sites, in refineries, on drilling rigs, following spill cleanup, and in industrial maintenance operations. Generally applied with standard pressure washing equipment. Most oil and tar build-up can be washed away on contact. For more severe contamination, use of a hot water system may yield better results.
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...
US Peroxide (USP) provides turn-key chemical management and field service programs to engineering companies and remediation technology applicators using In-Situ Chemical Oxidation (ISCO) or other technologies requiring chemical storage and handling. USP programs have proven to be cost effective and highly efficient using custom-designed chemical handling and management programs deployed by highly skilled field service teams.
USP can supply a wide range of chemicals such as hydrogen peroxide, ferrous...
Since 1998 IET has designed and implemented over 1500 remedial projects, including reductive biotic/abiotic approaches, ISCO, synergistic approaches, metals stabilization, DNAPL stabilization, soil mixing and combined remedies.
For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at...
Thermal Conduction Heating (TCH) is applicable in fractured rock and other complex formations such as: Tight and fractured clays,Saprolite, Shale, Sandstone, Limestone, Dolomite, Fractured igneous and metamorphic rock, Permeable basalt, Karst limestone.
AquaGate+RemBind is a composite particle consisting of an aggregate core coated with the reactive commercial adsorbent RemBind. This unique product facilitates the uniform delivery of powdered RemBind, for the in-situpassive removal of Per- and Polyfluoroalkyl Substances (PFAS) in groundwater or surface drainage systems.
Need to eliminate iron bacteria? Need to remove Hydrogen Sulfide? Oxidize iron and manganese?. Bio-hydrox is a non-toxic Chlorine alternative advanced oxidation product certified NSF/ANSI 60 and available in the USA market since 2013. It is sometimes called “liquid ozone” because it acts similar to ozone when reacts with water.
It is estimated that there are over 3,000 former Manufactured Gas Plant (MGP) sites across the United States. Another 4,000 dot the landscape of Canada, the UK, continental Europe and Japan. These sites were built long ago on rivers or harbors, often on the outskirts of towns and cities; locations that are now frequently in close proximity to infrastructure, buildings and residential areas. Many underlie or abut valuable commercial, residential, and municipal properties, posing environmental hazards to ground and...
