Sustainable and Efficient Wastewater Treatment Using Cellulose-Based Hydrogels: A Review of Heavy Metal, Dye, and Micropollutant Removal Applications

Separations, Год журнала: 2025, Номер 12(3), С. 72 - 72

Опубликована: Март 18, 2025

The rapid pace of global industrialization and population growth has intensified freshwater scarcity water pollution, necessitating urgent solutions. Adsorption technology, favored for its cost-effectiveness, simplicity, scalability, emerged as a promising approach. Hydrogels, particularly cellulose-based hydrogels (CBHs), have gained significant attention green adsorbents due to their biodegradability, non-toxicity, low cost, exceptional adsorption capacity. This paper reviews recent advancements in CBHs sustainable wastewater treatment, focusing on synthesis techniques, performance, mechanisms removing heavy metals, dyes, micropollutants. Updated applications outcomes are also discussed. Despite advantages, face challenges such limited mechanical strength, practical production difficulties, insufficient reuse studies, separation inefficiencies. review addresses these issues explores future prospects implementation. findings provide valuable insights into advancing efficient treatment

Microplastics in the Environment: A Review Linking Pathways to Sustainable Separation Techniques

Separations, Год журнала: 2025, Номер 12(4), С. 82 - 82

Опубликована: Март 30, 2025

Since the mid-20th century, quantity of microplastics (MPs) has increased significantly, becoming a persistent environmental pollutant widely distributed in global water bodies, soils, and atmosphere. While plastic materials have brought significant convenience to daily life, MPs resulting from their degradation pose increasing threats ecosystems human health. This comprehensive review examines sources, migration pathways, ecological impacts MPs, critically evaluates current separation techniques physical, chemical, biological perspectives. In particular, numerical simulations hydrocyclone technique reveal its unique flow characteristics, including turbulent velocity gradients axial pressure differences, with efficiency up 93%. offers advantages such as high efficiency, low energy consumption, friendliness. response growing microplastic pollution issue, this emphasizes that development future should prioritize sustainability, compatibility. Continued research field will provide theoretical support for optimizing control technologies contribute achieving protection sustainable goals.

Treatment of Oily Effluents Using a Bacterial Cellulose Membrane as the Filter Bed

Опубликована: Июнь 11, 2024

One of the main challenges in treatment industrial wastewater is removal oil-in-water emulsions, which are stable and therefore difficult to treat. Bacterial cellulose (BC) has structural characteristics that make it an ideal filtration membrane. The present study investigated effectiveness a BC membrane system for oily wastewaters. results demonstrated highly effective at removing contaminants (~99%), reducing colour particulate matter wastewater, as well eliminating nearly entire microbiological load (~99%).
