Abstract: The present invention provides a filter for separating particles and/or catalyzer for particle reaction in a fluid. The device comprising array of passageways fabricated on a die wherein the passageway size is controlled by actuators. The passageway size is monitored and the actuators controlling the passageway size are activated conditionally upon the passageway size monitoring. Using movable actuators the passageway can achieve passageway size that is less then the fabrication minimal resolution. Proper locating, setting and/or activation of the actuators create passageways that can perform filtration of particles, trapping of particles and catalyzing particles reaction.

Abstract: A hybrid type fiber filtering apparatus includes an enclosure, a strainer, a first filtering layer and a second filtering layer. The enclosure has an upper case and a lower case coupled to the upper case. The strainer is mounted inside the upper case in a longitudinal direction. The first filtering layer includes a plurality of fiber filters fixed between upper and lower fixing units and surround an outer circumferential surface of the strainer. The second filtering layer includes a plurality of fiber ball filters disposed inside the lower case. Raw water introduced into the upper case through a raw water inflow pipe passes through the first filtering layer, flows into the strainer, drops downwardly from an inside of the strainer, is introduced into the lower case, passes through the second filtering layer, and then, is discharged out through a filtered water discharge pipe.
