Membrane bioreactors for winery wastewater treatment : case-studies at full scale

The membrane bioreactor technology (MBR) is nowadays a suitable alternative for winery wastewater treatment, thanks to low footprint, complete suspended solids removal, high efficiency in COD abatement and quick start-up. In this paper, data from two full-scale MBRs equipped with flat-sheet membrane...

520 |a The membrane bioreactor technology (MBR) is nowadays a suitable alternative for winery wastewater treatment, thanks to low footprint, complete suspended solids removal, high efficiency in COD abatement and quick start-up. In this paper, data from two full-scale MBRs equipped with flat-sheet membranes (plant A and plant B) are presented and discussed. COD characterisation by respirometry pointed out the high biodegradability degree of both wastewater, with a strong prevalence of the readily biodegradable fraction. An extended version of Activated Sludge Model No. 3 was used to fit the experimental OUR profiles and to assess the maximum growth rate of heterotrophic biomass on sludge samples collected at both sites; the stoichiometric yield coefficients were also calculated. Sludge filterability and dewaterability were investigated with batch tests; laboratory results confirmed the field observations. Finally, some considerations are listed, aimed at defining possible key-issues for optimal process design and operation
