“…After energy capture by anaerobic microbial technologies, the effluent is usually rich in humic, fulvic, and ionic organic components, which can compete with P for adsorption sites, thereby interfering with recovery of P in downstream processes such as ion exchange . Hence, efficient strategies may be needed to polish the effluent for full recovery of the mobile P. This may include polymeric ligand exchange based on high selectivity between iron oxide and phosphate, , perhaps in combination with selective advanced oxidation and biodegradation of the residual organic fraction to release more recoverable P. , …”

Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements in P-use efficiency. While this motivation is increasingly being recognized, little P recovery is practiced today, as recovered P generally cannot compete with the relatively low cost of mined P. Therefore, P is often captured to prevent its release into the environment without beneficial recovery and reuse. However, additional incentives for P recovery emerge when accounting for the total value of P recovery. This article provides a comprehensive overview of the range of benefits of recovering P from waste streams, i.e., the total value of recovering P. This approach accounts for P products, as well as other assets that are associated with P and can be recovered in parallel, such as energy, nitrogen, metals and minerals, and water. Additionally, P recovery provides valuable services to society and the environment by protecting and improving environmental quality, enhancing efficiency of waste treatment facilities, and improving food security and social equity. The needs to make P recovery a reality are also discussed, including business models, bottlenecks, and policy and education strategies.

“…It was found that under certain biochemical conditions, emissions can vary significantly. Gupta and Novak (2013) fractionated based on its molecular weight cut off (MWCO) the thermal hydrolysis / anaerobic digestion centrate, both untreated and biologically treated was and further analyzed the fractions for total organic carbon (TOC), UV254 absorbance and organic nitrogen (ON). They determined that an MBR with a 300 kDa MWCO would be effective for the treatment of the recycle stream as it could remove up to 80 % of the organic matter, 60% of the UV254 quenching substances and 65% of the organic nitrogen.…”

A review of the literature published in 2013 on topics relating to water resource recovery facilities (WRRF) in the areas of modeling, instrumentation, automation and optimization of wastewater treatment is presented. Note that WEF has adopted the term ‘WRRF’ replacing such previous terms as publicly owned treatment works, wastewater treatment plant, and other conventional terms and officially instituted this change in its publications beginning in 2012. It is anticipated the replaced terms will remain in use by other publications and authors for some time.
