Summary: The study demonstrated an efficient method for recovering energy, nitrogen, and phosphorous from settled sewage using algal biomass through hydrothermal liquefaction. By optimizing parameters such as leaching time, base concentration, liquid:solid ratio, and temperature, over 86% of phosphorous from biochar could be extracted at a cost of $4.54/kg. Additionally, a three-step procedure was developed to recover high-purity biofertilizers from the phosphorous-rich eluate, achieving 95.4% phosphorous recovery at $5.29/kg.

Summary: This study investigated the optimized conditions for treating swine wastewater and producing struvite crystals using swine slurry, commercial MgCl2, and seawater as magnesium sources. The results showed that swine slurry is a feasible alternative for nutrient recovery. Under the conditions of pH 9.0 and [P]0/ [Mg]0/ [N]0 M ratio = 1.2/1.0/1.0, the struvite precipitation process achieved high removal efficiencies for nitrogen, phosphorus, and magnesium. The harvested precipitate had a high struvite content with low heavy metal impurity, making it suitable for use as fertilizer.

Summary: This study investigated the migration of tetracyclines (TCs) during struvite recovery from swine wastewater, revealing that TCs transport is contributed by various processes including the adsorption of pure struvite crystals, struvite adsorbing DOM-TCs complex, and DOM aggregation. Additionally, under alkaline conditions, larger molecular weight DOMs hydrolyze to smaller molecular weight DOMs, promoting the redistribution of TCs among different DOM types.

Summary: Crystallization of struvite from supersaturated solutions prepared by adding slurry of Mg(OH)(2) or brucite-equilibrated aqueous solution was investigated for N and P recovery from municipal wastewater. The precipitation followed the surface diffusion mechanism according to the polynuclear model. The precipitation rate was lower for the slurry prepared supersaturated solution compared to the brucite-equilibrated solution. Simulated wastewater supersaturated with brucite showed a higher precipitation rate. P recovery from simulated wastewater reached 70%.

Summary: Precipitation of mineral phosphates is an effective method for phosphorus recovery from wastewater. This study investigated the optimal operating parameters for phosphorus precipitation from aerobic wastewater liquor. It was found that solution pH had a significant effect on phosphorus precipitation, while the reactor's retention time did not. The use of calcium hydroxide for pH adjustment showed great potential for phosphorus recovery in the form of calcium phosphate-rich precipitates, with lower operating costs and higher energy sustainability compared to struvite precipitation.

Summary: Phosphorus is an essential element for organisms, but the natural phosphorus cycle has been disrupted by overexploitation and discharge into water bodies. Electrochemically induced phosphate precipitation offers a potential solution for phosphorus recovery by creating a localized high pH environment. Factors such as pH, current density, electrode configuration, and water matrix affect the performance of electrochemical systems. Future research should focus on evaluating long-term performance, developing an automatic process for harvesting deposits, and assessing economic feasibility.

Summary: A tandem strategy was developed to recover NH4+ and PO43- nutrients in a solid form from simulated wastewater after Fenton oxidation of organic contaminants. Mesoporous Cu-MgO nanoparticles were used as a catalyst for the oxidation of paraoxon and tetracyline while mesoporous MgO nanoparticles were used as the Mg-source for struvite crystallization. Fenton oxidation was necessary to remove hazardous contaminants before struvite synthesis, and the resulting product was verified to be struvite free of organic contaminants through XRD and Raman spectroscopy.

Summary: Phosphorus is an important element for human, animal, and plant life. The recovery of phosphorus from wastewater as calcium phosphate presents a low-cost and effective method, and the recovered CaP can be used as fertilizer and for other industrial applications. This review summarizes the effects of various factors on the precipitation/crystallization process and evaluates the efficiency and value proposition of recovered CaP. It also identifies process parameters for further optimization and provides perspectives on expanding the application field of recovered CaP.

Summary: Calcium carbonate scaling in industrial cooling circuits is a major issue that reduces heat exchange efficiency. Injecting an inhibitor polymeric additive in circulating water is a preventive treatment method. This study conducted scaling experiments in pilot plants with and without additives, and used the CooliSS software developed by EDF company for simulation. A local inhibition law of CaCO3 crystal growth was discovered and implemented to calculate the overall variation of calcium in the pilot plant. A small amount of additive quickly reduces the calcium deposit. The presence of suspended solids in water decreases the overall inhibition by adsorbing onto solids other than calcite (illite and SiO2).

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
