SHORT DESCRIPTION

An innovative microfiber capture device featuring a cage-like structure with multiple branches that efficiently collects microfibers from water.

BACKGROUND

Microfibers, a prevalent form of microplastic, challenge existing water treatment methods due to labor-intensive removal processes, limited adaptability to fiber sizes, and dependence on fabric-based systems. Current technologies often require external energy and do not adequately address the variability in microfiber geometries. This invention introduces a novel cage-like design to overcome these hurdles by enhancing contact area and simplifying fiber removal.

ABSTRACT

This invention employs a cage-like geometry composed of multiple branches arranged to leverage rotational water flow, thereby capturing microfibers with high efficiency. The increased effective contact area facilitates fiber collection within an open central cavity, overcoming the size limitations of traditional membrane filtration systems. Furthermore, its compatibility with established 3D printing processes enables scalable and cost-effective manufacturing, making it a versatile solution for integration into residential, industrial, and medical water systems.

APPLICATIONS

• Home appliances integration: Suitable for washing machines and water tanks.
• Plumbing systems and water purifiers: Effective for both residential and industrial setups.
• Wastewater treatment: Enhances microplastic removal in treatment facilities.
• Medical filtration: Applicable in hemodialysis and pharmaceutical filtering systems.

ADVANTAGES

• Broad Microfiber Capture: Accommodates a wide range of microplastic sizes and materials.
• Overcomes Size Limitations: Captures particles beyond the exclusion threshold of traditional filters.
• Cost-effective Manufacturing: Leverages accessible 3D printing processes for scalability.
• Easy Maintenance: Features an open design for convenient fiber removal without external energy.
