This study investigated the ability of waste-derived cellulose materials to remove nitrate from water through adsorption processes. First, a variety cellulosic waste were screened quantify their adsorptive nutrients water. Due low capacity and frequent leaching observed in raw materials, quaternary ammonium functionalization was then employed. Materials functionalized by adding cationic groups biowaste form novel ion exchange adsorbents containing naturally derived biopolymers and/or whole natural fibres with improved binding capacity. Results revealed that originating high can be successfully used Significant removed flax cellulose, comparable treatment efficiency commercial polystyrene-based material drinking filters.

Abstract Membrane filtration is a major process used in the energy, gas separation, and water treatment sectors, yet efficiency of current membranes limited. Here, we review use machine learning to improve membrane efficiency, with emphasis on reverse osmosis, nanofiltration, pervaporation, removal pollutants, pathogens nutrients, separation carbon dioxide, oxygen hydrogen, fuel cells, biodiesel, biogas purification. We found that brings substantial improvements performance leading specialized remarkable potential for various applications. This integration offers versatile solutions crucial addressing global challenges sustainable development advancing environmental goals. techniques capture purification industrial gases, aiding reduction dioxide emissions.

Abstract Rainwater harvesting (RWH) is principally based on collecting, storing, and using rainfall which would otherwise be lost as surface runoff. Runoff threatens in several ways: accelerating erosion, intensifying flooding, reducing groundwater recharge. Therefore, purposely retaining the urban water cycle rather than draining has positive impacts designing sustainable cities. This work presents a proposal how to avoid flooding cities by systematically harvesting, storing rainwater, it for multiple purposes. The concept of RWH presented here potential radical innovation solve social, economic, environmental challenges associated with flash flooding. Each residence regarded production unit. Depending climatic conditions, people can meet their needs local household basis, or alternatively use piped complement. By infiltrating locally recharged downstream wells are more productive. implementation this idea involves entrepreneurial agency that existing structures, adapting them. Clearly, social entrepreneurship expected catalyse realization innovation, also rural areas. It about mobilizing ideas, capacities, resources create transformation.

ABSTRACT Safe water quality is essential for human consumption. Therefore, this study aimed to investigate and health risks, including the hazard quotient (HQ) index (HI). Samples were collected from six sites (S1–S6) of groundwater resources, aqueducts (Ganats), cisterns, distribution network Gonabad city in autumn 2023. Data (WQI) show that distribution, cisterns (site 2 site 3), Ganats 1), cistern 1) have good (WQI < 50), poor 50–75), very > 75) drinking purposes, respectively. The results risk models indicate HQ value exceeds World Health Organization recommendations children at S5. Moreover, total (THI) levels ranged 0.19 0.937 adults 0.51 2.45 children.
