Metabolic modelling of full-scale enhanced biological phosphorus removal sludge.
This study investigates, for the first time, the application of metabolic models incorporating polyphosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs) towards describing the biochemical transformations of full-scale enhanced biological phosphorus removal (EBPR) activated sludge from wastewater treatment plants (WWTPs). For this purpose, it was required to modify p...
متن کاملBiological Phosphorus Removal Potential Test
Biological phosphorus removal (BPR) techniques offer a number of advantages over chemical addition, including enhanced treatment, reduced energy consumption, and reduced sludge production. A rapid, low-cost method for determining the feasibility of biological phosphorus removal should allow these techniques to be more widely used. A simple test is proposed to determine the amount of phosphorus ...
متن کاملIn Enhanced Biological Phosphorus Removal ( Ebpr ) Processes
Phosphorus is an essential element for every living organism, but when it exceeds certain limit in water bodies, it will cause serious environmental issues, such as eutrophication. P accumulation in water bodies can be caused by non-point sources, such as agriculture land runoff, as well as from point sources such as wastewater effluent discharges. In order to avoid eutrophication of water bodi...
متن کاملEnhanced Biological Phosphorus Removal within Membrane Bioreactors
Several Membrane Bioreactor (MBR) facilities have been constructed with the intent of providing Enhanced Biological Phosphorus Removal (EBPR), and several additional such plants are being designed and constructed. Full-scale plant information is now available for process designers to better understand the unique design and operating issues associated with the incorporation of EBPR designs in MB...
متن کاملMetabolic behaviour of Acinetobacter spp. in enhanced biological phosphorus removal - a biochemical model
A biochemical model is presented that explains the behaviour of Acinetobacter spp. in enhanced biological phosphorus removal activated sludge systems. The model modifies and extends the proposals of Comeau et al. (1985). Two key parameters are identified in controlling poly-P and PHB synthesis and degradation, the ATP/ADP and NADH/NAD ratios. The predicted behaviour appears to be consistent wit...
