“…Thus, the need for novel treatment technologies is increasing to eliminate these bottlenecks for efficient wastewater treatment. Research on biological wastewater treatment is currently directed toward resource recovery (Franca et al 2018 ; Guven et al 2023 ). Aerobic granular sludge (AGS) technology, an innovative technology that permits simultaneous carbon and nutrient removal, has been increasingly used for municipal wastewater treatment (de Bruin et al 2004 ; de Kreuk et al 2007 ; Winkler et al 2015 ; Kosar et al 2022a ; Cicekalan et al 2023 ).…”

Recently, one of the main purposes of wastewater treatment plants is to achieve a neutral or positive energy balance while meeting the discharge criteria. Aerobic granular sludge (AGS) technology is a promising technology that has low energy and footprint requirements as well as high treatment performance. The effect of co-treatment of municipal wastewater and food waste (FW) on the treatment performance, granule morphology, and settling behavior of the granules was investigated in the study. A biochemical methane potential (BMP) test was also performed to assess the methane potential of mono- and co-digestion of the excess sludge from the AGS process. The addition of FW into wastewater enhanced the nutrient treatment efficiency in the AGS process. BMP of the excess sludge from the AGS process fed with the mixture of wastewater and FW (195 ± 17 mL CH4/g VS) was slightly higher than BMP of excess sludge from the AGS process fed with solely wastewater (173 ± 16 mL CH4/g VS). The highest methane yield was observed for co-digestion of excess sludge from the AGS process and FW, which was 312 ± 8 mL CH4/g VS. Integration of FW as a co-substrate in the AGS process would potentially enhance energy recovery and the quality of effluent in municipal wastewater treatment. Graphical abstract

“…Among the different contributors to the generation of contaminated water, industry is one of the most prominent sources. Chemical, pharmaceutical, and textile industries generate important amounts of wastewater [1], which should be properly treated to both promote the recycling of the same water and send it back to the environment with the lowest possible pollutant concentration. Wastewater can present many different species of pollutants: organic and inorganic chemicals, dusts, solids, and biological agents [2].…”

Graphene oxide and its magnetic nanoparticle-based composites are a well-known tool to remove heavy metals from wastewater. Unfortunately, one of the major issues in handling such small particles consists of their difficult removal from treated wastewater (even when their magnetic properties are exploited), due to their very small diameter. One possible way to overcome this problem is to embed them in a macroscopic biopolymer matrix, such as alginate or chitosan beads. In this way, the adsorbent becomes easier to handle and can be used to build, for example, a packed column, as in a traditional industrial adsorber. In this work, the removal performances of two different embedded magnetic nanocomposite adsorbents (MNAs) are discussed. The first type of MNA is based on ferrite magnetic nanoparticles (MNPs) generated by coprecipitation using iron(II/III) salts and ammonium hydroxide, while the second is based on a 2D material composed of MNP-decorated graphene oxide. Both MNAs were embedded in cross-linked alginate beads and used to treat artificial water contaminated with chromium(III), nickel(II), and copper(II) in different concentrations. The yield of removal and differences between MNAs and non-embedded magnetic nanomaterials are also discussed. From the results, it was found that the time to reach the adsorption equilibrium is higher when compared to that of the nanomaterials only, due to the lower surface/volume ratio of the beads, but the adsorption capacity is higher, due to the additional interaction with alginate.

“…A pragmatic shift marked a transformation in waste material management and wastewater treatment technology, responding to the substantial global waste production and the demand for economical adsorbents to reduce wastewater treatment costs [4]. Today, a new approach encompasses the integration of waste materials into wastewater treatment and the creation of value-added products from previously used waste adsorbents, including electric material and cementitious materials, ultimately enhancing both waste management efficiency and commercial viability [5][6][7]. Wastewater is generated from various sources, including industrial processes, agricultural activities, and domestic usage [8,9].…”

The primary objective of this research was to assess the efficacy of a novel solution under conditions closely resembling those of real-world scenarios. Biological beds, or filters, hold significant potential for widespread implementation in individual households, particularly in areas with dispersed housing. The system’s aim was to improve the quality of wastewater treated in on-site domestic biological treatment plants. A pivotal aspect of the project involved developing a prototype research installation for conducting comprehensive testing. Our installation system consisted of several components designed to create a laboratory-scale model for domestic wastewater treatment. The model comprised four biological reactors filled with ABS material and secured by a PUR frame. Additionally, the tested model included a controller for wastewater dosing control, a septic tank as a reservoir, and four tanks for collecting purified wastewater. Through regression analysis using the Generalized Linear Model (GLM), a correlation between CODCr and TSS was revealed. This study presents the research findings concerning the development of a prototype installation that incorporates an advanced reactor or filter. The data derived from this research have the potential to contribute to the creation of products that enhance the performance and efficiency of household wastewater treatment systems.
