Patent DE-4138617-A1 (DE)
Title: Biological decontamination of soil contg. hydrocarbon - by addn. of malachite green oxalate and N-cetyl-N,N,N-tri:methyl:ammonium bromide to promote growth of bacteria breaking down hydrocarbon(s) etc.
Inventor: JOSEWSKY TILO
IPC: A62D3/02
Filed: 1991-11-25
Abstract: In the biological decontamination of soil contaminated with hydrocarbons, the natural bacterial compsn. of the soil is altered by addn. of 0.0037% of malachite green oxalate and 0.003% of N-cetyl-N,N,N-trimethylammonium bromide in such a way that multiplication of non-fermenting bacteria which break down hydrocarbons is promoted, and multiplication of types which do not, or hardly, cause breakdown, is retarded. To maintain the efficiency of metabolism of the non-fermenters, nutrients with a deficiency in C cpds. are added to the water, using MgSO NH4C1 and Na2 HPO4 as nutrients. The bioavailability of the hydrocarbons is improved by addn. of 3 pts. of water to 5 pts. of soil. During 24 h, the water is circulated once through an aeratable, temp.-controllable fermentor. ADVANTAGE - Treatment time is shorter.

Patent DE-4227962-A1 (DE)
Inventor: HAEGEL FRANZ-HUBERT DR
IPC: B01D11/02
Filed: 1992-08-22
Abstract: In order to decontaminate solid materials contaminated with organic pollutants, in particular soil contaminated with polycyclic aromatic hydrocarbons, the materials are mixed with a micro-emulsion, if required after being crushed and mechanically disaggregated. The organic impurities are solubilized in the apolar compartment of the micro-emulsion and the micro-emulsion is decomposed, in particular by temperature change, into a tenside-rich phase and into a pollutant-containing phase. By using micro-emulsions of biodegradable components, the purified solid materials, in particular purified soil, may be returned to the environment. A plant for carrying out the process has a multiple-stage extraction device (3), in which the contaminated solid material is mixed with the micro-emulsion and the impurities concentrate in the apolar oil phase. In a separating device (6), the extracted solid material is separated from the contaminated micro-emulsion, which is then decomposed in a phase separating device (8) into a tenside-rich water phase, collected in the container (11), and into a pollutant-containing oil phase (oil container 12). By using biodegradable components for the micro-emulsion, the pollutant-containing oil phase can be reacted in a micro-organism reactor (14) in order to achieve its total degradation.
