ConspectusHuman interference in natural biogeochemical cycles has caused an unprecedented input of reactive phosphorus and nitrogen nutrients into the environment, contributing to perturbations aqueous ecosystems (e.g., eutrophication). Furthermore, industrial mining Haber–Bosch ammonia production contribute significantly global energy expenditures greenhouse gas emissions. Existing wastewater treatment techniques, particularly those based on adsorption processes, have predominantly concentrated nutrient removal, underutilizing potential for subsequent recovery pure products. Recovering these from wastewaters municipal, industrial, agricultural) can supplement fertilizer production, leading emissions savings a more circular resource economy. In addition, provides economic incentives expand implementation water treatment, which exhibits additional benefits, such as public health environmental remediation. Phosphate total (i.e., TAN, sum ammonium) are emphasized this Account because they comprise substantial portions nitrogen.Adsorption-based processes promising due their simple construction maintenance, scalability, cost-effectiveness. However, phosphate TAN is generally attained through ion exchange (electrostatic attraction), nonselective interaction. Additionally, acid or base used adsorbent regeneration contributes most embedded process. If could achieve high target selectivity regenerability, then valuable products be recovered efficiently economically. Because uniquely strong nucleophiles among species, leveraging ligand (coordinate covalent bonding) enhance against competing ions. mild pH speciation equilibria that interrupt coordinate bonds, minimized, mitigating major contributors energy, emissions, cost.In Account, we summarize our recent work two adsorbents: (1) ferric oxide-loaded poly(vinylbenzyl trimethylammonium) anion resin selective municipal (2) zinc polyacrylate weak cation hydrolyzed urine. To maximize selectivity, capacity, regenerability without eluting immobilized electrophile oxide divalent zinc) adsorbent, all interactions between solutes, electrophile, support polymer must carefully controlled favor desired bonds. optimize efficiency material design, electrochemical systems, supplemental characterization techniques also discussed.

This research focuses on the production of a liquid stream rich in volatile fatty acids (VFAs) and low ammoniacal nitrogen content (<0.1 g N/L) from biowaste. The was obtained by combining (i) mixed culture acidogenic fermentation to maximise VFA (ii) gas-permeable membrane (GPM) contactor recover nitrogen. Three batch tests biowaste collected full-scale mechanical-biological treatment plant provided high stable concentrations (37-39 CODVFA/L). VFAs represented 73-81% soluble chemical oxygen demand (sCOD) concentration, with predominance acetic, propionic butyric acids. A highly specialized microbial community observed all tests, Bacteroidota Firmicutes as predominant phyla (>90% relative abundance). GPM recovered more than 99% without losses. suitability produced C/N ratio for downstream applications evaluated using biomethane potential (BMP) at different total ammonium (TAN) (0.76-3.15 circumneutral pH. Despite achieving similar ultimate methane yields (279-314 NmL CH4/g CODfeed), lower TAN improved anaerobic biodegradation kinetics, enhancing its applicability production.
