“…Membrane filtration methods include nanofiltration (NF) for molecules within the 300-500 Da molecular weight range [19] and reverse osmosis (RO) through a pressure-driven separation [20]. Other recent alternative techniques have also been employed, such as coagulation/flocculation, electrocoagulation, electro-floatation, and electro-deposition [21]. However, these methods may have drawbacks, such as incomplete metal removal, sludge generation, high reagent and energy requirements, and membrane fouling [22].…”

Tanning, crucial for leather production, relies heavily on chromium yet poses risks due to chromium’s oxidative conversion, leading to significant wastewater and solid waste generation. Physico-chemical methods are typically used for heavy metal removal, but they have drawbacks, prompting interest in eco-friendly biological remediation techniques like biosorption, bioaccumulation, and biotransformation. The EU Directive (2018/850) mandates alternatives to landfilling or incineration for industrial textile waste management, highlighting the importance of environmentally conscious practices for leather products’ end-of-life management, with composting being the most researched and viable option. This study aimed to isolate microorganisms from tannery wastewater and identify those responsible for different types of tanned leather biodegradation. Bacterial shifts during leather biodegradation were observed using a leather biodegradation assay (ISO 20136) with tannery and municipal wastewater as the inoculum. Over 10,000 bacterial species were identified in all analysed samples, with 7 bacterial strains isolated from tannery wastewaters. Identification of bacterial genera like Acinetobacter, Brevundimonas, and Mycolicibacterium provides insights into potential microbial candidates for enhancing leather biodegradability, wastewater treatment, and heavy metal bioremediation in industrial applications.

“…Based on the current advances, it has been estimated that, to achieving the different SDG six targets by 2030, the pace of implementing basic drinking water need to be increased twice, while safely managed drinking water and basic sanitation need to increase four times (Padhye et al, 2022). To support the successful achievement of these targets, there is a significant variety of innovative processes that can be applied to improve water quality (Villasenor-Basulto et al, 2022). These processes, however, can be both extremely costly and require a long treatment time (Ortiz-Marin et al, 2022).…”

Editorial on the Research Topic Advanced physico-chemical technologies for water detoxification and disinfectionOne of the most critical challenges we face today is access to clean water. Climate change, industrialization, high rates of urbanization, and population growth have resulted in many countries suffering from water crises, especially in the arid and semi-arid areas. Countries in different regions of the world have also been struggling over regional water availability and it is anticipated that these struggles may result in conflicts over shared water resources in these regions. Considering the adverse consequences of the water crisis, countries have been trying to increasingly cope with this problem of water availability by implementing sustainable water management plans and looking for alternative water supply sources.Water conservation, water reuse, and desalination of seawater and brackish groundwater are among those strategies that have been implemented to address the water crises. In recent years, more and more countries are considering water reuse as an alternative water supply to supplement freshwater sources. Water reuse decreases the pressure on freshwater resources, reduces the pollution that is being discharged to water bodies, and can be a reliable source compared to other water resources that are directly dependent on rainfall. One of the barriers to water reuse is concern over its potential negative impact on human and environmental health. Even today, treated and untreated wastewater reuse is sometimes poorly controlled. A large portion (estimated at over 80% globally, and over 95% in some developing countries) of the world's wastewater is still released to the environment without treatment. The current challenge is to make reuse circuits shorter, safer, and economically sustainable.Access to safe drinking water, sanitation, and hygiene is a basic human need for sustainable health and wellbeing. Nevertheless, billions will lack access to these basic services in 2030 unless progress to accomplishing the Sustainable Development Goals (SDGs) increases in the following 8 years (Padhye et al., 2022).
