Integrated Municipal Wastewater Treatment Process for Water Reuse

This project develops an integrated municipal wastewater treatment process that combines advanced engineered treatment with a nature-based solution to produce effluent for non-potable applications. Initially, municipal wastewater is treated in a state-of-the-art Membrane Aerated BioReactor (MABR). This system employs oxygen-permeable membranes to optimize biological processes, enhancing nitrification and denitrification with low energy demand and adaptability to varying loads. Following the MABR stage, the effluent is further treated using a living wall system. This vertical bioreactor integrates diverse vegetation and engineered substrates to support robust microbial communities that remove residual nutrients and contaminants. The living wall not only further treated the MABR effluent but also offers an environmentally friendly and aesthetically appealing component that can be incorporated into urban infrastructure. The final treated effluent is intended for non-potable reuse applications such as landscaping and toilet flushing. These applications provide practical benefits by reducing freshwater consumption while supporting sustainable urban landscaping and recreation.
