Abstract. This research investigated biodegradation of several halogenated methanes under methanogenic conditions. Biodegradation of dichloromethane to C02 and acetic acid (both environmentally acceptable products) was demonstrated in a fixed-film reactor, operated at 20 deg C, a residence time as low as day, and an influent concentration of 91 micro M.

This chapter outlines fundamental— and often special —characteristics of biofilm systems in the water industry. Building on these fundamentals, the describes how the water industry uses biofilms as the heart of technology that improves water quality. Finally, it highlights the ways in which biofilms cause problems in the water industry and strategies to counter the by: mechanism of aerobic & an-aerobic biodegradation presented by: sukhjeet kaur bt(h)3sem 10/5/ 1 2.

The biodegradability of chlorinated methanes, chlorinated ethanes, chlorinated ethenes, chlorofluorocarbons (CFCs), chlorinated acetic acids, chlorinated propanoids and chlorinated butadienes was evaluated based on literature data. Evidence for the biodegradation of compounds in all of the compound categories evaluated has been reported. A broad range of chlorinated .
Enhanced anaerobic bioremediation is the practice of adding hydrogen to soil and groundwater to increase the number and vitality of indigenous microorganisms performing anaerobic bioremediation. In this process, anaerobic microbes substitute hydrogen for chlorine on chlorinated contaminant molecules, dechlorinating the compound. Anaerobic digestion has been widely applied to treat the waste activated sludge from biological wastewater treatment and produce methane for biofuel, which has been one of the most efficient solutions to both energy crisis and environmental pollution challenges. Anaerobic digestion sludge contains highly complex microbial communities, which play crucial roles in Cited by: In Situ Remediation Using Anaerobic Biotransformation of Groundwater Contaminated with Chlorinated Solvents.

Achieving the removal of chlorinated ethenes as well as 1,4-dioxane to below health advisory levels in groundwater that has anaerobic and aerobic zones has proven to be challenging.
