Anaerobic Membrane Bioreactor + Reverse Osmosis: a novel solution for resource recovery from dairy wastewater
Anaerobic membrane bioreactor (AnMBR) + reverse osmosis (RO) is a novel solution that allows complete anaerobic treatment of dairy wastewater without aerobic post-treatment,enables successful water re-use and promotes nutrient recovery.In this configuration the AnMBR facilitates the maximum recovery ofbiogas while producing an effluent with very low COD,no suspended solids but still with high concentrations of soluble nutrients.The RO coupled directly after the AnMBR produces,without aerobic treatment,a premium quality permeate fit for re-use as well as a reject stream with concentrated nutrients that facilitates their efficient recovery.The results presented in this abstract confirm the performance of the first full-scale AnMBR + RO plant,which is also in line with the performance observed during prior pilot trials on site (also reported).After only 3 months of ramp-up,the 2875 m3 full-scale AnMBR is able to treat the full wastewater flow from the dairy factory with COD removal efficiencies of 99%,membrane fluxes of 20-25 L/(m2.h) and volumetric loading rates (VLR) up to 4.6 g COD/(L.d).The RO system directly coupled downstream achieves further COD reductions down to 3 mg/L as well as successful up-concentrations of nutrients in the reject-stream of up to 3 times.
