MBR technologies are quickly becoming the norm for municipal wastewater treatment facility upgrades, providing high-capability biological treatment and membrane filtration within a small footprint. Higher biomass concentrations are possible than with conventional activated sludge treatment and significantly smaller land use is possible, making it a big advantage where space is at a premium. According to the U.S. EPA, MBRs replace secondary clarifiers and sand filters so both greater treatment capacity and higher effluent quality are possible within the same or smaller space. Because the membranes are a physical barrier, water leaving the system is pathogen-free and solids-free and can go directly into reuse applications like agricultural irrigation and landscape watering. Around the world, high-profile municipal MBR applications ranging from Stockholm city upgrades to Beijing treatment centers with advanced technologies cement growing use of the technology as cities confront tighter water quality controls and water supply issues.
Zero Liquid Discharge (ZLD) growth in heavy industries is one of the strongest growth prospects within the water treatment space. Governments are increasingly making ZLD mandatory for water-conductive industries like textiles, chemicals, and power plants in water-scarce nations like India, where the Central Pollution Control Board made ZLD norms mandatory within industrial centers like Surat to avoid effluent dumping. Even the economics of ZLD is strong: World Bank case histories show projects where water reuse revenues paid full operating costs and recovered capital expenditures within five years. Innovations are making ZLD feasible on increasingly complex industrial effluents where new and improved RO, electrodialysis (ED), and membrane distillation (MD) are lowering the energy footprint and extending their use to high-saline streams.
As the impact of climate change and deteriorating infrastructure elevates the need for emergency intervention, demand is growing for modular, containerized water treatment units. Portable, multi-technology water purification with options for alternative power is available with technologies such as the U.S. EPA's Water-on-Wheels (WOW Cart), and water can be safely delivered within hours of flooding or hurricanes or when contaminants are introduced. Beyond the emergency context, modular units are being used as scaleable infrastructure solutions when deployed to remote communities and temporary installations when plants are being refurbished. Current Opinion in Environmental Sustainability has reported industry research promoting modular water systems as a long-term decentralized approach improving urban water security when integrated, variably flexibly, with centralised networks and new developments like atmo-pheric water harvesting.
