Air Sparging
Air sparging is a almost always used to treat hydrocarbons (fuels and oils) contamination. In simple terms this technique involves pumping air through water. This has 2...
Groundwater Chemical Treatment
Chemox (Chemical Oxidation) is an excellent technology for treating groundwater whilst it is in the ground. Chemox will often also reduce contamination levels in soils (see Chemox in...
Extraction & Disposal
Extraction & Disposal can be a simple and economic approach to a complicated problem, as with all remediation techniques, they nearly all do what they say...
Pump & Treat
Pump & Treat is one of the more common forms of groundwater treatment, pumping groundwater through a treatment system, then discharging either back to ground,...
Thermal Desorption
Thermal desorption is a process where heat is used to remove contaminants from soil. Heating certain contaminants will reduce their concentrations. The most common use...
Soil Washing
Washing soils is more often than not about sorting soils into different constituent parts, gravels, sands and other fines. It’s difficult to explain ‘why?’ without...
Stabilization
Environmental stabilization of soils is carried out with the intention of tying up contamination so that the risk from contamination is removed. This should facilitate...
Soil Chemical Oxidation
UNOF Environmental solutions specialise in the treatment of contaminated soil through chemical application. The most common form of treatment is chemical oxidation (chemox for short). Other...
