ANAEROBIC TREATMENT OF HIGH SALINE WASTEWATER USING HALOPHILIC METHANOGENS IN ANAEROBIC FILTERS
A large number of industrial processes generate wastewater containing high salinity. The presence of a high concentration of sodium in wastewater is considered inhibitory for anaerobic biological treatment. This research was designed to investigate the potential use of halophilic methanogens, and a mixed culture of halophilic methanogens and digester sludge, in anaerobic filters, for treatment of organic pollutants in high saline wastewater at 35° C. Data related to start-up of the filters are presented. Both halophilic and mixed culture anaerobic filters were able to operate at a NaCl concentration of 35 g/L, at organic loading rates of 6.2 and 5 kg COD/m3·d,respectively. COD removal efficiency was as high as 80%, and the systems were able to maintain a low volatile fatty acids concentration of 500 mg/L. Higher salt or higher organic loading rates caused system imbalance. Increasing the salt concentration to 37 g/L at an organic loading rate of 3 kg/m3.d caused system failure.
