“…Notably, Ye et al (2019b) tested three types of membranes (CEM, forward osmosis membrane, and nonwoven membrane) and found that MFC with CEM had the best P removal effectiveness (95%). However, the use of membranes could trigger problems, such as membrane fouling and high internal resistance of the reactor, which could lower energy efficiency and increase the cost (Blatter et al, 2020;Cusick et al, 2014;Happe et al, 2016;Kumar et al, 2019;Marassi et al, 2020).…”

“…After 173 days of treatment, the reactor was almost filled with precipitates. Happe et al (2016) constructed a 3 L triple-chamber MFC to treat digested sewage sludge containing iron phosphate, and 67% P was recovered as struvite. Blatter et al (2020) conducted a pilot test to treat wet sewage sludge containing iron phosphates with a 168 L MEC and 97% P was recovered.…”

Phosphorus (P) is an essential element for the growth and reproduction of organisms. Unfortunately, the natural P cycle has been broken by the overexploitation of P ores and the associated discharge of P into water bodies, which may trigger the eutrophication of water bodies in the short term and possible P shortage soon. Consequently, technologies emerged to recover P from wastewater to mitigate pollution and exploit secondary P resources. Electrochemically induced phosphate precipitation has the merit of achieving P recovery without dosing additional chemicals via creating a localized high pH environment near the cathode. We critically reviewed the development of electrochemically induced precipitation systems toward P removal and recovery over the past ten years. We summarized and discussed the effects of pH, current density, electrode configuration, and water matrix on the performance of electrochemical systems. Next to ortho P, we identified the potential and illustrated the mechanism of electrochemical P removal and recovery from non-ortho P compounds by combined anodic or anode-mediated oxidation and cathodic reduction (precipitation). Furthermore, we assessed the economic feasibility of electrochemical methods and concluded that they are more suitable for treating acidic P-rich waste streams. Despite promising potentials and significant progress in recent years, the application of electrochemical systems toward P recovery at a larger scale requires further research and development. Future work should focus on evaluating the system's performance under long-term operation, developing an automatic process for harvesting P deposits, and performing a detailed economic and life-cycle assessment.

“…Prior to liquid-solid separation of slurry-like organics, release of P from the solid to the liquid fraction can be facilitated by processes such as bioelectrochemical systems (e.g. Fischer et al, 2011;Happe et al, 2016), ozonation (e.g. Suzuki et al, 2006), additional anaerobic tanks or zones in enhanced biological phosphorus removal (EBPR) schemes (e.g.…”

The need for better nutrient management has spurred efforts towards more comprehensive recycling of nutrients contained in human excreta to agriculture. Research in this direction has intensified throughout the past years, continuously unfolding new knowledge and technologies. The present review aspires to provide a systematic synthesis of the field by providing an accessible overview of terminology, recovery pathways and treatment options, and products rendered by treatment. Our synthesis suggests that, rather than focusing on a specific recovery pathway or product and on a limited set of nutrients, there is scope for exploring how to maximize nutrient recovery by combining individual pathways and products and including a broader range of nutrients. To this end, finding ways to more effectively share and consolidate knowledge and information on recovery pathways and products would be beneficial. The present review aims to provide a template that aims to facilitate designing human excreta management for maximum nutrient recovery, and that can serve as foundation for organizing and categorizing information for more effective sharing and consolidation.

“…Once P is in solution, struvite can be produced by the addition of Mg and parts of ammonium. This process, despite being currently very time consuming (10‐80 d), seems promising, since no chemical pH adjustments are needed . Metallurgical processes like Mephrec produce P‐rich slags, with low concentrations of heavy metals, where P is bound in the form of calcium silicon phosphates .…”

This Mini Review gives an overview of and respective references for the current situation regarding global phosphorus reserves and the legal situation for P recovery using Germany as the model. Apart from the well‐known pilot up to industrial/full scale recovery techniques, emerging chemical and bio‐based P recovery techniques are named without claiming to be all‐encompassing. Special attention is paid to the biological systems for P recovery that reveal ways for use of renewable resources as raw materials. A few chemically based recovery techniques like AirPrex®, (Ostara)PEARL™, AshDec®, and RecoPhos® have already been used to recover P at a rate and quality which allows for its sale as a fertilizer. Many chemically based processes are at the stage of investigation on a pilot or laboratory scale, e.g. P‐RoC, LeachPhos, and Mephrec®. All of the biologically based technologies like P‐Bac are still at an early stage of research and show promising results. Of all recovered materials struvite, calcium phosphate and biological bound phosphorous seem to have the best plant availability. Although there is no ultimate “one fits all” technology, potential P‐recovery plant operators can choose from a wide range of techniques which will best fit local raw material availability, economic and ecological situation.
