“…It has been observed that similar systems with gravity flow can sustain continuous operation for up to 1 year without incurring in operatively dis-habilitating fouling (Zhang et al 2006). This is contrary to similar trials conducted with actual membranes (pore size 0.1 μm) in similar conditions, where the medium filtration capacity decreased by 77% after just 3 months, requiring membrane substitution and/or regeneration (Pikorova et al 2009).…”

“…Use of membrane systems in decentralized treatment of household (domestic) wastewater was described by several researchers (Meuler et al 2008;Blstakova et al 2009;Pikorova et al 2009;Matulova et al 2010;Chong et al 2013). MBRs, when properly operated, have also shown the capability to effectively remove nutrients and, to some degree, micropollutants, from a waste stream (Abegglen et al 2008).…”

In many Countries, small communities are required to treat wastewater discharges to increasing standards of lesser environmental impacts, but must achieve that goal at locally sustainable costs. While biological membrane treatment (membrane bio-reactors (MBRs)) is quickly becoming the industry standard for centralized wastewater treatment plants, and would also be ideally suited also for small plants potentially subject to relatively large hydraulic load variations, its investment and operating costs are usually high for that class of applications. Consequently, small treatment plants are generally configured as anoxic or aerated biological tanks with little sedimentation, making them quite susceptible to hydraulic loads transient and sludge quality changes. As an alternative, Constructed Wetlands Systems (CWSs) are gradually and successfully being introduced in many Countries. CWSs are designed to utilise the natural functions of wetland vegetation, soils and their microbiological populations to treat wastewater. Pretreatment occurs by filtration and settling, followed by bacterial decomposition in a natural-looking lined marsh. A new technology, a new type of membrane-like aerobic reactor initially designed for the degradation of hydrocarbon-derived groundwater contaminants, was recently tested for treating domestic, with performance similar to that of MBRs. Examples from the above applications are illustrated and compared in this paper. The paper also discusses merits and drawbacks of the various illustrated technologies, in view of their sustainability potential, and according to the new development paradigms for urban water systems, that encourage the development of local water-cycle clusters with local reuse and recycle of the resource, and possible local recovery of energy and/or materials.

A new type of membrane-like aerobic reactor initially designed for the degradation of hydrocarbon-derived groundwater contaminants was tested for treating domestic wastewater. The biomass concentrator reactor (BCR) consists of an enclosed, aerated tank containing a graded filtration medium with the function of solids separation, and was previously used to treat industrial wastewaters containing refractory substances, with good results. It is a small-footprint reactor that could be operated in remote areas with no long-range sewage connections, with few appropriate controls and little monitoring instrumentation. The BCR was run for 90 days in pilot conditions with domestic wastewater feed. Results of the application are illustrated in the paper.
