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

Water, Journal Year: 2024, Volume and Issue: 16(12), P. 1675 - 1675

Published: June 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).

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

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(10), P. 2449 - 2459

Published: July 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

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).

Adaptable Process Design as a Key for Sustainability Upgrades in Wastewater Treatment: Comparative Study on the Removal of Micropollutants by Advanced Oxidation and Granular Activated Carbon Processing at a German Municipal Wastewater Treatment Plant

Sustainability, Journal Year: 2022, Volume and Issue: 14(18), P. 11605 - 11605

Micropollutants have been increasingly detected at low concentrations in surface waters and may harmful effects on humans, organisms, the environment. As wastewater treatment plants are one of main sources micropollutants, conventional methods (mainly to three cleaning stages) must be improved through an advanced (fourth) stage. The optimal fourth stage should determined based not only removal efficiencies but also a holistic sustainability assessment that further considers process’s adaptability, economic, environmental, social parameters. ability tertiary plant remove organic pollutants was investigated over four months using two different methods: (1) oxidation process (AOP) (using UV + H2O2) (2) granular activated carbon (GAC). resulting average micropollutant were 76.4 ± 6.2% for AOP 90.0 4.6% GAC. GAC became saturated, it showed decreasing performance from 97.6% week 80.7% 13, after 2184 bed volumes processed. For AOP, adjusting H2O2 doses results higher efficiencies. With 40 ppm 10 kJ/m2 UV, 97.1% achieved. Furthermore, flexibility adaptability adjust real-time water quality, along with lower resource consumption waste disposal, make more promising technology when comparing aspects methods.
