Other filter mechanisms are hydrosol filtration, such as the fiber filters in HVAC systems, and cyclonic filtration, used in bagless vacuum cleaners.<\/p>\n<p>\u201cThere are lots of different types of filters used for many purposes worldwide, but they\u2019re all based on just a few fundamental mechanisms,\u201d said Strother, who collaborated with corresponding author Misty Paig-Tran and Raj Divi of Cal State Fullerton.<\/p>\n<p>Manta rays, close relatives of sharks that can measure more than 20 feet across, eat by bringing plankton-rich water into their mouths as they swim. They filter and ingest the plankton and then flush the remaining water out their gill slits.<\/p>\n<p>Many filtration systems are prone to clogging as they collect whatever they\u2019re filtering out, but manta rays use arrays of leaf-like lobes to bounce food particles away from the filter.<\/p>\n<p>Water passing over the lobes creates a complex pattern of swirling eddies, and food particles in the flow hit the lobes and move away. The setup allows the fish to retain food organisms much smaller than the pores.<\/p>\n<p>\u201cThis paper establishes the basic mechanism, and we are currently looking at whether we can adapt this mechanism for engineered systems,\u201d Strother said. \u201cFor example, one future direction is exploring whether this can be applied to wastewater treatment in order to address the emerging threat from microplastics pollution.\u201d<\/p>\n<p><a href=\"https:\/\/today.oregonstate.edu\/news\/manta-rays\u2019-food-capturing-mechanism-may-hold-key-better-filtration-systems\"><strong>Read complete
