“…At C/N ratio of 5 (stage VII) and 8 (stage VIII), comparatively stable TN removal was achieved at 38% and 60.3%, respectively. This indicated that the increase of influent C/N ratio is beneficial for TN removal, which was consistent with previous research conclusions [38,42].…”

The increasing threat to human health and aquatic life caused by nitrogen pollution in surface waters requires critical attention. The membrane-aerated biofilm reactor (MABR) is a promising alternative compared to conventional technologies. In this work, a pilot-scale MABR system was employed to treat polluted surface water in continuous-flow mode. The nitrogen removal performances with the variations of the aeration parameters, hydraulic loading and C/N ratio were explored. The results showed that intra-membrane pressure plays a dominant role in improving the denitrification rate. The nitrification dynamics of the MABR system were favoured in conditions of low influent C/N ratios and hydraulic loading, but limit the denitrification process due to insufficient carbon source. A counter optimal hydraulic loading of 0.016 m 3 /(m 2 day) (hydraulic retention time of 36 h), and a corresponding increase in the influent C/N ratio was beneficial for nitrogen removal. When the influent C/N ratio was raised to a factor of 8, the total organic carbon (TOC), ammonium and total nitrogen (TN) removal efficiency could reach 80.0%, 92.2% and 60.3%, respectively. This indicated that the MABR has a potential to remove TN by simultaneous nitrification and denitrification (SND) in polluted surface water treatment.

“…Although there is a lack of literature on upscaling algal biofilm systems from laboratory to full scale, particularly for the use of nutrient removal from municipal wastewater (Kesaano and Sims, 2014), the potential of such systems warrants their consideration. Algal biofilm systems, as with bacterial biofilms, present a possibly option for small-scale treatment locations due to their resilience to changes in environmental conditions and ability to retain biomass (Sun et al, 2015;Praveen and Loh, 2016). For example, Sukacova et al (2015) achieved P removal rates of up to 98% using a biofilm photobioreactor treating real wastewater.…”

“…MABRs behave differently to conventional biofilms due to the presence of gas exchange, adding a layer of complexity to the treatment process (Martin and Nerenberg, 2012). They have been successfully commercialized for N removal and recent studies report total Premoval of up to 90% when used with an SBR (Sun et al, 2015). The technology shows potential in terms of energy efficiency and reduced maintenance requirements (Nerenberg, 2016), but much work is required before their use for EBPR is proven at fullscale.…”

The removal of phosphorus (P) from domestic wastewater is primarily to reduce the potential for eutrophication in receiving waters, and is mandated and common in many countries. However, most P-removal technologies have been developed for use at larger wastewater treatment plants that have economies-of-scale, rigorous monitoring, and in-house operating expertise. Smaller treatment plants often do not have these luxuries, which is problematic because there is concern that P releases from small treatment systems may have greater environmental impact than previously believed. Here P-removal technologies are reviewed with the goal of determining which treatment options are amenable to small-scale applications. Significant progress has been made in developing some technologies for small-scale application, namely sorptive media. However, as this review shows, there is a shortage of treatment technologies for P-removal at smaller scales, particularly sustainable and reliable options that demand minimal operating and maintenance expertise or are suited to northern latitudes. In view of emerging regulatory pressure, investment should be made in developing new or adapting existing P-removal technologies, specifically for implementation at small-scale treatment works.

“…. A sequencing batch membrane-aerated biofilm reactor (SBMABR) with intermittent aeration and artificially enhanced biofilm shedding was employed to enhance biological nitrogen and phosphorus removal (Sun, Wang et al, 2015). A long-term reactor operation showed that the removal efficiencies of COD, NH4 + -N, total nitrogen (TN) and TP in SBMABR were maintained above 90%, 96%, 91% and 85% respectively.…”
