Advances in membrane separation of urban wastewater effluents for (pre)concentration of microcontaminants and nutrient recovery: A mini review

Chemical Engineering Journal Advances, Год журнала: 2022, Номер 11, С. 100298 - 100298

Опубликована: Март 31, 2022

This revision work focuses on the recent advances in separation of microcontaminants from urban wastewaters, using ultrafiltration and Nanofiltration membranes. Conventional systems show advantages such as low pressure fouling, competitive energetic- maintenance costs compared to reverse osmosis, higher rejection rates organic membrane distillation. However, these strongly depend temperature, flow, pressure, well surface charge concentration, challenging adequate treatment more complex matrices. Recent material science improved implementation possibilities different types. In conventional industrial processes especially wastewater treatment, offering not only cost reducing solutions for but also efficiency remediation a high variety wastewaters. Moreover, great potential applicability added value substance recovery wastewaters agricultural, chemical consumer industry, sustainable natural resources use. Finally, perspectives promising technologies combination methods trains, advanced oxidation processes, are given, aiming zero-liquid discharge, prevent valuable passing through focusing closing water cycle.

Predictive Capability of Phosphate Recovery from Wastewater Using a Rough Set Machine Learning Model

ACS ES&T Engineering, Год журнала: 2024, Номер 4(10), С. 2449 - 2459

Опубликована: Июль 31, 2024

Phosphate recovery from wastewater treatment plants has recently become the focus of waste management sector. Indeed, a real-time facility on commercial scale necessitates using advanced prediction techniques to improve planning and execution procedures. Although many machine learning studies have been reported predict phosphate recovery, there are no general rules for recovering different sources. This study aims apply rough set (RSML) based decision attributes. rule-based classifier model generates IF–THEN classify conditional attributes achieve proper decision. The identified solution pH, initial (P) concentration, Mg/P Mg/N ratios along with operational parameters like reaction time retention as core attributes; oversight these may lead misprediction P recovery. generated 104 rules, including 16 approximate rules. accuracy trained RSML was 91.42%, performing better than that existing models. results this RSML-based predictive will significant implications scientific future work in fields

Nutrient Recovery via Struvite Precipitation from Wastewater Treatment Plants: Influence of Operating Parameters, Coexisting Ions, and Seeding

Water, Год журнала: 2024, Номер 16(12), С. 1675 - 1675

Опубликована: Июнь 12, 2024

Phosphorus (P) is a critical element for life, and wastewater treatment systems can be strategic points its recovery, thereby avoiding eutrophication pollution in nature. The aim of this research was to investigate P recovery via struvite, namely terms the influence operating parameters, coexisting interfering ions, seeding. This paper focuses on synthetic solutions, although an assessment performed wastewater. results indicated that, solution, minimum concentration struvite precipitation about 30 mg P/L, that Mg/P molar ratio 1 promotes removal efficiency with less contribution from other minerals. In order assess real-world scenarios, ions (calcium sodium) investigated. Calcium shown have greatest impact process, as 80% removed initial 200 Ca/L. Indeed, these experiments generated amorphous precipitate did not contain struvite. utilization biomass ash (size < 63 µm) seeding crystallization increased compared sample without seed helped control pH. demonstrated good efficiencies (over 90%) but reduction purity final product (struvite minor crystalline phase identified XRD—15%wt).

Developing sustainable materials for recovering and recycling nutrients from wastewater is critically needed such as phosphorus that have a diminishing supply. Struvite crystallization emerging promising strategy recovery which can be enhanced with seeding through microalgal biochar. The main bottleneck of using microalgae its high harvesting cost. In this study, an integrated electrocoagulation-flotation (ECF) process used to recover at the same time modify algal surface magnesium anode inert carbon cathode. Harvesting efficiency 98% was achieved 40.78 mA cm-2, 0.5 cm inter-electrode distance energy consumption 4.03 kWh kg-1 in 15 min. harvested were pyrolyzed obtain yield 52.90% Mg-laden Simultaneously, impregnation 28% attained confirmed by Scanning electron microscopy (SEM) dispersive X-ray spectroscopy (EDS). Phosphorus struvite 93.70% 2.66 g L-1, respectively, obtained dosing 1.50 L-1 Comparison physicochemical characteristics residual supernatant after showed combined use both residuals serve growth medium microalgae. overall operating cost found 2.48 USD total 10.76 kg-1, lower than conventional unit processes centrifugation filtration. This novel approach help attaining circular bioeconomy encompassing nutrient waste management process.
