Summary: The study combines granulated biomass fly ash (GBFA) with the Fenton process to enhance the removal of adsorbable organic halides (AOX) from pulp bleaching wastewater. The optimal treatment setup involves sequential treatment by the Fenton process followed by GBFA, resulting in the highest AOX removal (60-70%), reduced COD, and enhanced wastewater biodegradability. GBFA can be recovered and reused without regeneration, yielding similar AOX removal compared with fresh GBFA. Furthermore, the operating cost of this treatment setup is lower than that of conducting the Fenton process alone.

Summary: Resource reuse has become important in wastewater management, with the use of sludge in agriculture being a major route. Enhanced removal of heavy metals during primary treatment can decrease concentrations in both effluent and sludge for long-term reuse. Specific assessment of technologies for improved heavy metal removal is needed due to variations in total heavy metal concentrations in raw wastewater. Coagulation/flocculation and low-cost sorbents are promising methods for enhancing heavy metal removal during primary settling.

Summary: The use of natural flocculants in the coagulation-flocculation process for water and wastewater treatment has gained attention for its simplicity and safety. This study evaluated the performance of pomegranate seed powder as a novel natural flocculant for treating pulp and paper wastewater (PPWW). The results showed that pomegranate seeds contained active substances that contributed to their coagulating ability, achieving high removal efficiencies of COD and turbidity when used at optimal dosages. Dual flocculation of pomegranate seeds and alum showed a synergistic effect, resulting in even higher removal rates and shorter treatment time.

Summary: This study focused on recovering phosphate and generating electricity from anaerobic sludge digested wastewater using iron-air fuel cells. The two-chamber fuel cell showed higher phosphate removal efficiency, vivianite yield, and electricity generation efficiency compared to the one-chamber fuel cell. The proton exchange membrane in the two-chamber fuel cell provided suitable conditions for vivianite formation and low pH, leading to high conductivity and low internal resistance, benefiting electricity generation. The two-chamber fuel cell was the better choice for phosphate recovery and electricity generation from ASD wastewater.

Summary: The productivity of an orchard depends on soil fertility and nutrient requirements of fruit trees. The extractability of phosphorus (P) from soils affects P sorption, release patterns, and P bioavailability. A study was conducted to investigate P extractability using seven extraction methods in relation to soil properties in three fruit orchards. The results showed significant differences in soil properties among orchards and different P extraction methods extracted different pools of soil P. The study suggested the importance of considering soil properties for predicting P bioavailability using these methods in different soils.

Summary: The roles of suspended and fixed sludge in substrate transformations were investigated in a microbial fuel cell (MFC) with a progressively decreasing suspended sludge at a fixed nitrate concentration. The fixed sludge at the electrode showed greater contributions compared to the suspended sludge. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) analysis demonstrated that the suspended sludge improved electron transport capacity and reduced internal resistance. The best electricity generation performance was achieved using only fixed sludge at the electrode.

Summary: The present research investigates the effect of tetracycline, a highly toxic and broad-spectrum bacteriostatic antibiotic pollutant, on the operational efficacy of a microbial fuel cell (MFC) in terms of nutrient and pollutants removal. The results show that the removal efficiency of the MFC increases with an increase in tetracycline concentration. The maximum removal efficiency, voltage production, power density, and current density are achieved at 25 mg L-1 of tetracycline. Furthermore, the study also examines the influence of tetracycline as a co-substrate, revealing that the removal efficiency and voltage output of different substrates are inversely proportional to the amount of tetracycline.

Summary: Recent studies have focused on the application of pressure vessels (PVs) for controlling transient pressure caused by pump failure. However, little research has been done on integrating PVs into an instantaneous acceleration-based (IAB) model for transient flow analysis. This study utilizes the IAB unsteady friction (UF) model to accurately predict the transient response of a pumping pipeline protected by a PV. A novel approach is also explored to increase the working efficiency of the PV during transient events through a modified connection configuration. The results show that the developed model accurately reproduces the transient waves in a pumping system and the redesigned connection configuration reduces the required volume of the PV by up to 70% while maintaining cost-effectiveness.

Summary: The presence of heavy metals and volatile fatty acids can impact the transformation of organics by anaerobic bacteria, inhibiting the degradation of waste. Knowing the concentrations of these substances during wastewater treatment is crucial to prevent operational disruptions. Microtox analysis provides quick and reliable information about the toxic concentrations of mixtures. This study evaluated the effects of Pb, Cd, Cu, and VFAs on P. phosphoreum and found additive or synergistic toxic effects. Understanding these toxicity effects can help optimize bioreactors and use P. phosphoreum as a biosensor for metals and VFAs.
