Description
This session showcases emerging water technologies, innovations, and best practices for efficient water treatment, desalination, water reuse, and water conservation in different sectors.
There is a growing interest in the adsorption of pollutants on biosorbents, especially those of plant origin. This study deals with the development of activated carbon based on PFCP waste by phosphoric acid activation and their application as adsorbents of methylene blue dye. The activated carbon obtained was characterized by physicochemical methods and complementary analyses. The different...
Desalination of seawater and brackish water is one possible response to water crises and shortages. In our work we have explored one of the desalination methods based on Reverse Osmosis, using a layer of a two-dimensional material as a membrane in the filtration process of this fluid.These criteria led us to choose a material from the Transition Metal Dichalcogenide (TMD) family, the chosen...
Wastewater treatment for water reuse has received considerable attention owing to water resource shortage. One of the most effective wastewater treatment methods involves the use of column filtration systems (CFS). Biochar-based column filtration systems (BCFS) for wastewater treatment have gained attention in the last decade. In this study, decanted wastewater was treated by using a...
Abstract:
Microalgae hold promise as sustainable and renewable resources for phenolic compound removal. Industrial mill wastewater often contained phenol. In this work, we isolated and identified a freshwater diatom through 18S DNA analysis, Navicula permitis. Then, we assessed its ability to grow and effectively eliminate phenolic compounds at concentrations ranging from 50 to 250 mg/L to...
This study introduces transformative ceramic membranes for sustainable wastewater treatment and reuse, focusing on regions grappling with water scarcity and pollution. The integration of magnesium aluminosilicate-based ceramics, derived from industrial by-products, yields efficient membranes with exceptional properties. Comprehensive microstructural analyses reveal their composition and...
Olive mill wastewater (OMWW) remains a primary environmental challenge in regions with significant olive oil production. This by-product is rich in polyphenols, organic compounds that, despite their health benefits when consumed in foods, can be environmentally detrimental when released untreated into ecosystems due to their potential toxicity, recalcitrance, and the oxygen depletion they can...
Morocco is among the countries, in Africa, exposed to the lack of water. In order to optimize water resources, it is advisable to both consider an appropriate water management strategy and find new sources of water. In this context, the leachate from landfills may constitute a relevant source of water. Our study aims to treat leachate with sugar lime sludge and phosphates washing sludges to...
Water management is rapidly becoming one of the most pressing issues all countries in semi-arid and arid parts of the world are facing. Global water consumption is predicted to increase by 50% in 2030 , which will cause an acute water shortage. Presently, the agricultural sector consumes more than 70% of freshwater in most regions of the world1, putting more pressure on water needs and...
The utilization of wastewater presents a sustainable solution to combat water scarcity, offering numerous advantages like bridging the gap between supply and demand, reducing pollution of freshwater sources, providing a robust approach to addressing water scarcity and climate change, and contributing to the achievement of the Sustainable Development Goals. The Multi-Soil-Layering (MSL) system...
In this study, we present a sustainable approach for the production of activated carbon derived from olive pits using chemical activation with potassium hydroxide impregnation. The resulting activated carbon is subsequently employed to fabricate composite materials in combination with sodium alginate (AC/Alg) for potential applications in wastewater treatment.
The production process involves...
Water is one of the most precious natural resources. It is an essential need and an indispensable component for the survival of all forms of life on this planet. Without water there is no life on Earth. Sadly, however, water contamination by organic, inorganic and biological pollutants has become a serious problem throughout the globe. Much worse, the recent expansion of human activities...
The global water crisis (e.g. water shortage, water pollution, and water-related disasters) is one of the greatest risks the human society is currently facing. Recently, photocatalysis over semiconducting materials has emerged as a promising technology for wastewater treatment1. Thus, looking for inexpensive and highly efficient photocatalytic materials toward the complete degradation of water...
The ability of Marine Biomass-supported Zinc Oxide (CT/ZnO) biocomposite has been tested for the removal of Congo Red (CR) from an aqueous solution. The biomaterial characteristics were analyzed, and X-ray diffraction (XRD) results confirmed the presence of peaks associated with zinc oxide and calcium carbonate. The optimum conditions for the effective removal of CR onto CT/ZnO are pH= 6,...
In regions where wastewater laden with high concentrations of trace metallic elements, emanating from industrial activities like mining, pose an imminent threat to both the environment and public health, innovative purification techniques become imperative. This study focuses on the application of one such technique, Slow Sand Filtration (SSF), in the context of wastewater treatment near the...
