Membrane bio-reactors for decentralized wastewater treatment and reuse.
Decentralized wastewater treatment is the key to sustainable water management because it facilitates effluent (and nutrient) reuse for irrigation or as service water in households. Membrane bioreactors (MBR) can produce effluents of bathing water quality. Septic tanks can be retrofitted to MBR units. Package MBR plants for wastewater or grey water treatment are also available. Systems for decentralized treatment and reuse of domestic wastewater or grey water are also feasible for hotels, condominiums and apartment or office complexes. This paper presents the effluent qualities of different decentralized MBR applications. The high effluent quality allows infiltration even in sensitive areas or reuse for irrigation, toilet flushing and cleaning proposes in households. Due to the reusability of treated water and the possibility to design the systems for carbon reduction only, these systems can ideally and easily serve to close water and nutrient loops.
