ClearAdvancing bacterial cellulose biopolymers & hydrogels to remediate microplastic pollution
Researchers developed bacterial cellulose biopolymers and hydrogels as biodegradable alternatives to fossil-fuel-based filters for removing microplastics from wastewater, optimizing operational parameters using response surface methodology. Results showed removal efficiencies of up to 99% for concentrated MP suspensions, with flow cytometry, electron microscopy, and ATR-FTIR confirming the flocculation mechanism and the potential for large-scale industrial application.
Efficacy of bacterial cellulose hydrogel in microfiber removal from contaminated waters: A sustainable approach to wastewater treatment
Researchers developed a bacterial cellulose hydrogel made from unused cellulose remnants and tested it as an eco-friendly filter for removing microfibers from contaminated water. The hydrogel achieved an average removal rate of nearly 94 percent and retained the captured fibers well, releasing only about 8 percent after washing. The study presents this bio-based approach as a sustainable and effective alternative for tackling microfiber pollution in wastewater.
Bacterial cellulose biopolymers: The sustainable solution to water-polluting microplastics
Researchers developed bacterial cellulose (BC) biopolymer filters as a sustainable alternative to petroleum-based polymer filters used in wastewater treatment plant microplastic removal. BC filters showed high MP capture efficiency and are biodegradable, addressing both microplastic pollution and the environmental costs of conventional synthetic filter maintenance.
Tailored cellulose-based flocculants for microplastics removal: Mechanistic insights, pH influence, and efficiency optimization
Researchers developed plant-derived (cellulose-based) flocculants that clump microplastics together so they can be more easily removed from water, finding that a low concentration of 0.001 g/mL was optimal and that both electrical charge and water-repelling interactions drive the process depending on the type of plastic.
Design of model microplastics to study their transport in urban waters
Researchers designed model microplastic particles with controlled physical properties to systematically study their transport behavior in urban water systems. The work provides a foundation for understanding how microplastic size, density, and shape influence fate and transport in stormwater and urban drainage networks.
Microplastic removal in coagulation-flocculation: Optimization through chemometric and morphological insights
Researchers optimized the coagulation-flocculation process — a standard water treatment step where chemicals cause particles to clump and settle — for removing three types of microplastics: polypropylene, polyethylene, and polystyrene. Polystyrene was removed most efficiently, and adjusting pH, coagulant type, and dosage significantly improved removal rates, providing practical guidance for upgrading existing water treatment plants to better capture microplastics.
Understanding and Improving Microplastic Removal during Water Treatment: Impact of Coagulation and Flocculation
Researchers systematically tested coagulation and flocculation for removing microplastics from drinking water, finding that removal efficiency depended strongly on plastic particle size and whether particles had been weathered, with smaller pristine particles being the hardest to remove.
Developing an Efficient Model for Microplastic Removal in Wastewater: Integrating Advanced Filtration, Nanotechnology, and Bioremediation
Researchers developed an integrated model for microplastic removal from wastewater combining bio-based filtration with chitosan and alginate beads, carbon nanotube nanotechnology, and bioremediation techniques. The study suggests that this synergistic approach addresses key limitations of conventional treatment methods, including insufficient removal efficiency, low adsorption capacity, and inadequate selectivity for different microplastic types.
Microplastics_Removal
Researchers evaluated the efficiency of a microplastic removal system for synthetic wastewater that combines a chemical treatment process with simple filtration, measuring removal performance across different microplastic types and concentrations.
Design of an Efficient Model for Microplastic Removal in Wastewater using Advanced Filtration, Nanotechnology, and Bioremediation
This paper proposed an advanced machine learning model to design and optimize microplastic removal in wastewater treatment, using process parameters to predict removal efficiency. The intelligent model outperformed conventional design approaches in predicting treatment outcomes.
Removal of Classical and Emerging Contaminants in Water Treatment Using Super-Bridging Fiber-Based Materials
Researchers designed iron-grafted cellulose fibers and tested them for removing both classical contaminants and emerging pollutants including microplastics from wastewater, demonstrating high removal efficiency across a broad range of contaminant types in a single treatment step.
