“…Other drinking water treatment technologies consistently use higher porous:surface area sorption ratios. For example, based on a maximum P-sorption capacity of 4.1 mg P (g resin) −1 , 60 the LayneRT resin has a ratio of 747 (see the SI, Section 2 for the calculations). The protein-based technology analysis included a more conservative ratio of 236.…”

Recovering phosphate (P) from point sources such as wastewater effluent is a priority in order to alleviate the impacts of eutrophication and implement a circular economy for an increasingly limited resource. Bioadsorbents featuring P-binding proteins and peptides offer exquisite P specificity and sensitivity for achieving ultralow P concentrations, i.e., <100 μg P L −1 , a discharge limit that has been implemented in at least one treatment facility in nine U.S. states. To prioritize research objectives for P recovery in wastewater treatment, we compared the financial and environmental sustainability of protein/peptide bioadsorbents to those of LayneRT anion exchange resin. The baseline scenario (reflecting lab-demonstrated performance at a full-scale implementation) had costs that were 3 orders of magnitude higher than those for typical wastewater treatment. However, scenarios exploring bioadsorbent improvements, including increasing the P-binding capacity per unit volume by using smaller P-selective peptides and nanoparticle base materials and implementing reuse, dramatically decreased median impacts to $1.06 m −3 and 0.001 kg CO 2 equiv m −3 ; these values are in line with current wastewater treatment impacts and lower than the median LayneRT impacts of $4.04 m −3 and 0.19 kg CO 2 equiv m −3 . While the financial viability of capturing low P concentrations is a challenge, incorporating the externalities of environmental impacts may provide a feasible path forward to motivate ultralow P capture.

“…Although thermal processes are sustainable recovery applications, they are still a costly option (Vaneeckhaute et al, 2017). Alternatively, there are many processes in which phosphorus is recovered by precipitation, adsorption and ion exchange from aqueous solutions (Biswas et al, 2009; Donatello, Tong, & Cheeseman, 2010; Fang et al, 2018; Pinelli et al, 2022). As 90% of influent phosphorus concentrates in the solid phase of the sewage sludge, dissolving chemically‐ or biologically‐bound phosphorus in the solid phase of the sludge is necessary before any recovery process (Antakyali et al, 2013; Desmidt et al, 2015).…”

Municipal digested sludge (MDS) has considerable phosphorus content that is between 1% and 15% in dry matter and it is a potential source for phosphorus recovery. A high amount of MDS is generated from sewage treatment plants in large cities and has many environmental concerns with its organic and inorganic constituents. In this study, phosphorus was recovered by precipitation with Ca(OH)2 and NaOH. Acid pretreatment was applied to MDS with H2SO4 and 58.7% of phosphorus was extracted from the solid phase to the liquid phase at pH 2. Up to 99% of dissolved phosphorus in the liquid phase was recovered with Ca(OH)2 and NaOH. Almost similar phosphorus precipitation rates were achieved with both bases but higher phosphorus contents (17% as P2O5) in precipitates were obtained by NaOH. The product obtained in this study can serve as a high‐quality raw material substitute for the low‐grade phosphate rocks (<15% P2O5) commonly utilized in the phosphate industry. Furthermore, this research presents a practical, environmentally friendly and cost‐effective approach for sustainable sludge management and phosphorus production.

“…In addition, ion exchange installations are much cheaper compared to reverse osmosis [36][37][38]. While using the ion exchange method during purifying water from phosphates, these ions can be removed from the solution, and it is expedient to obtain liquid fertilizers or other useful products from regeneration solutions [39][40][41][42]. The reuse of purified eluates allows reducing water purification costs and switching to low-waste technologies.…”

Надмірне надходження зі стічними водами промислових підприємств біогенних речовин, зокрема фосфору, спричиняє надмірну евтрофікацію природних водойм, що призводить до якісного виснаження водних ресурсів. Найбільш перспективним методом очищення води від фосфатів є іонний обмін. У роботі досліджені процеси сорбції фосфатів на високоосновному аніоніті в хлоридній та лужній формах. Досліджено процеси впливу конкуруючих аніонів на ефективність вилучення фосфатів. Встановлено, що селективність аніоніту АВ-17-8 збільшується в ряду хлориди-фосфати-сульфати. Показано, що для регенерації аніоніту в фосфатній та фосфатно-сульфатній формах доцільно використовувати розчини 10 % NH4Cl, 15 % NaCl, 6 % Na2CO3, 7 % KOH, 6 % (NH4)2SO4. Розроблені методи вилучення фосфатів із регенераційних розчинів, що робить їх придатними для повторного використання. Для створення безвідходних процесів було запропоновано спосіб вилучення фосфатів із води на аніоніті АВ-17-8 та його регенерацію, що дозволить вилучати фосфати у вигляді мінеральних добрив та багаторазово використовувати регенераційні розчини.
