“…Among the various decentralized wastewater treatment processes, the membrane bioreactor (MBR) technology offers the advantage of its relatively small size, which can operate with varying volumes of influent (Suneethi, 2009). An MBR plant can both handle high strength nitrate influent that is too enriched for classical biological systems and produce effluent quality that is higher than that from any other alternative biological wastewater treatment (Chon et al, 2011;Shen et al, 2009).…”

Irrigating turfgrass with treated effluent water has become a common practice in response to shrinking supplies of potable water. Newly developed decentralized water treatment systems produce recycled water containing varying quantities of N on short notice. Using such tailored water to irrigate turf areas would reduce or eliminate the need for additional mineral fertilizers if concentrations of nitrate in the water were raised during the growing season to meet the annual N requirement. On the basis of our estimates, in order for turfgrasses to receive their entire annual N requirements (20 to 25 g N m−2 yr−1) solely from effluent irrigation, nitrogen concentrations in irrigation water would need to range from as low as 11 mg L−1 for arid regions with a 12‐mo growing season to more than 50 mg L−1 in areas with only a 6‐mo growing season. Furthermore, tailored water should be applied with advanced irrigation systems with high distribution uniformity to minimize nitrate leaching. Subsurface irrigation systems distribute water more efficiently and uniformly and minimize human exposure to treated effluent, which would help dispel negative public perceptions regarding the use of effluent to irrigate public turf areas. As the use of treated effluent for turfgrass irrigation continues to increase, the idea of adjustable nutrient content in irrigation water combined with a subsurface irrigation delivery system could become an important means to sustainably maintain much‐needed urban green spaces.

A B S T R AC TAn anaerobic-anoxic-oxic membrane bioreactor for real municipal wastewater treatment was operated under various conditions in order to investigate extracellular polymeric substances (EPS) properties and their role in membrane fouling. Test results showed that EPS, proteins in EPS (EPS p ) and carbohydrates in EPS (EPS c ) had correlations with membrane fouling. EPS p were found to have more signifi cant correlations with membrane fouling while EPS and EPS c had loose correlations with membrane fouling, indicating that EPS p were an important factor in membrane fouling. Three-dimensional excitation-emission matrix fl uorescence spectra analysis revealed that Peak C had potential correlations with the membrane fouling. Peak C, which was associated with fulvic acid-like substances, should be mainly originated from microbial metabolism. Gel fi ltration chromatograph (GFC) demonstrated that the EPS had narrower molecular weight (MW) distribution compared to the infl uent wastewater. It was also found that the number-average MW (M n ) and the weight-average MW (M w ) of EPS increased with the increase of operation time.
