...Stephanie Young; Aotian Xu A low sludge discharge membrane bioreactor (LSDMBR) for greywater reclamation was developed and tested in this study. LSDMBR was designed by combining an aerobic activated sludge process with an immersed membrane filtration process. LSDMBR offers the following advantages...

...Aotian Xu; Stephanie Young; Yanqiu Zhang A single-sludge step-feed anoxic–aerobic process (SSFAOP), characterized by enhanced nitrogen reduction performance, long solids retention time (SRT), and short aerobic hydraulic retention time (HRT), was designed to optimize nitrification...

...Noreen M. Layden; Harlan G. Kelly; Donald S. Mavinic; Richard Moles; John Bartlett Autothermal thermophilic aerobic digestion (ATAD) is an exothermic process where sludge is subjected to temperatures greater than 55 °C for at least 4 hours, over 6–10 days. Organic solids are degraded and the heat...

...Noreen M. Layden; Donald S. Mavinic; Harlan G. Kelly; Richard Moles; John Bartlett Increased legislative constraints have fuelled an interest in developing sustainable and economical methods for sludge digestion. Autothermal thermophilic aerobic digestion (ATAD) is a robust process that produces...
