Paper compares pilot performance of NF and ultra low pressure RO (ULPRO) membranes in terms of rejection (TOC, and nutrients (NH3 and NO3-), conductivity, and selected trace organics), as well as operational performance (specific flux, and flux decline due to fouling) while treating nitrified and non-nitrified municipal effluent with an Integrated ...

This paper describes the development and optimization of an anaerobic membrane bioreactor for the treatment of mixed waste (i.e., municipal wastewater and food waste) and production of biogas for small and decentralized communities. A cross-flow ceramic ultrafiltration membrane pilot was backpulsed and operated intermittently at high cross flow vel...

Low-pressure membrane (LPM) technologies are becoming increasingly common in drinking water treatment, especially for the removal of disinfection byproduct (DBP) precursors. Removal of DBP precursors by LPMs requires pretreatment that may mitigate or exacerbate membrane fouling. A review of relevant literature has indicated that although a number o...

This presentation briefly summarizes the design and operation of a microfiltration for treating a pretreated produced water....
