Optimizing a Biomimetic Cross-Flow Microplastics Filter Inspired by Manta Rays — •Ioannis Gkekas1 and Tim Robertino Baumann2 — 1Universität Bielefeld — 2Universität Bielefeld
Microplastic pollution poses a significant threat to aquatic ecosystems, necessitating innovative filtration solutions. This study continues previous research on a biomimetic cross-flow filter inspired by manta ray feeding mechanisms. The objective is to optimize the filter's geometry and material properties to enhance efficiency and durability. Using COMSOL simulations, various geometrical configurations are being tested to identify an optimal design for maximizing filtration efficiency and clean water output. To address material durability, we reenforced PDMS (polydimethylsiloxane) with glass fibers to mitigate bursting under operational stress. Initial results indicate that the composite material significantly enhances durability compared to the original PDMS design. Once the simulations are complete, the optimal design will be fabricated for in-lab performance evaluation. This research advances the development of sustainable, high-efficiency microplastic filtration systems inspired by natural processes.
