This promotes phosphate removal … It is considered to be a cost effective and environmentally sustainable alternative to chemical treatment (Acevedo et al., 2012; Nguyen et al., 2013). State laws limit the levels of phosphorus that can be discharged from wastewater into the environment. Biological P removal, especially Enhanced Biological Phosphorus Removal (EPBR) with activated sludge systems, has been studied in depth in recent years. Efficient phosphorus removal from MBR effluent with heated aluminum oxide particles (HAOPs) 1. Generally, the enforcement of these laws also happens at the state level. Biological phosphorus removal (BPR) in this manner proceeds through recirculation of the sludge to an anaerobic zone. The Fe and P species and their transformation mechanisms via aerobic and anaerobic conditions were investigated with X-ray absorption near edge structure (XANES) spectroscopy.

Phosphorus removal is a bigger issue today than ever before. In the treatment of municipal wastewater, anaerobic conditions are applied as a treatment step in assisting the removal of phosphate from the water. Excessive discharge of wastewater-borne phosphorus (P) can lead to eutrophication of the receiving... 2. A new phosphorus (P) removal and recovery process that integrates an FeCl3-dosing, membrane bioreactor (MBR), and side-stream cofermentation was developed for wastewater treatment. Introduction. Many U.S. states currently regulate, or will soon regulate, these phosphorus levels. Municipal wastewater treatment plants might consider submerged membrane bioreactor technology for its phosphorous removal capabilities, on top of other benefits like improved COD and BOD reduction and greater treatment capacity within a … The pilot study demonstrates that lower effluent phosphorus levels can be achieved with an MBR system when compared to the conventional biological removal process. Materials and methods.
