An air filter and a method of air filtration using the said air filter are described. The air filter may comprise a filter media layer adapted to capture and filter one or more impurities from air. The air filter may further comprise one or more acoustic wave generating means attached at one or more sides of the filter media layer. The one or more acoustic wave generating means may generate acoustic waves to be propagated into the filter media layer. The propagation of the acoustic waves into the filter media layer may facilitate the filter media layer to enhance the filtration efficiency of the air filter. The air filter may further comprise a pre-programmed chip to control the frequency of the acoustic waves generated. Further, air filter may comprise a battery adapted to supply power to the one or more acoustic wave generating means and the pre-programmed chip.

A method for separating components from a fluid is disclosed. A cooling element is provided and is disposed in contact with a distal side of one or more thermally-conductive surfaces. One or more resistive heating elements are provided and are disposed in contact with or embedded in a proximal side of the one or more thermally-conductive surfaces. A fluid comprising one or more secondary components is provided. The fluid is passed across the one or more thermally conductive surfaces, the one or more secondary components freezing, crystallizing, desublimating, depositing, condensing, or combinations thereof, out of the fluid. The one or more resistive heating elements engage such that the one or more solid secondary components detach and pass out the solids outlet. The one or more resistive heating elements disengage, restarting production of the one or more solid secondary components.

A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.
