Use of membrane bioreactors for the bioremediation of groundwater polluted by chlorinated compounds

摘要: The aim of this experimental work has been the application a new polluted waters treatment technology for selection bacterial population capable bioremediating synthetic groundwater by four different chlorinated compounds. innovative applied in study was biological system known as MSBR (Membrane Sequencing Bioreactor), which consists Batch Reactor (SBR) coupled to membrane module filtration sludge that degrades compounds present water fed system. used experimentation contained compounds: 1,2-dichloroethane, 1,2-dichlorobenzene, 2-chlorophenol and trichloroethylene. During development research, were either alone on mixtures order identify possible effects each substrate degradability others. Some operational parameters varied check possibility implementing at larger scale. equipped effective acclimation hardly biodegradable xenobiotic compounds, degradation rates achieved comparable other similar studies performed, even if experimentation, differing from all others found literature, good removal substrates when they mixtures.
