Document Type and Number:
WIPO Patent Application WO/2023/142511
Kind Code:
A1
Abstract:
An apparatus of a micro-sized material separation system by using sweeping acoustic wave to collect and agglomerate micro-sized material from a fluid medium such that the micro-sized material can be trapped and controlled easily for possible after-treatment. It allows continuous flow and processing of the subject fluid medium, and continuous collection of targeted micro-sized material without any chemicals involved. The micro-sized materials can be any matter including but not limited to, dust, particulates, fibers, cells, etc. It has great application potential in areas requiring water purification and particularly in textile industry for recycling of synthetic fibers from laundry sewage water.
