US 6,547,855 B1 · Mass transfer system

Abstract

A mass transfer machine removes dissolved gases or volatile organic compounds from air or a liquid. The mass transfer machine includes a vessel capable of containing a liquid and having a liquid inlet and an air inlet at a near end. It further includes a liquid outlet at a far end. Two or more baffles are located transversely inside of the vessel. The baffle located nearest to the far end of the vessel has a window. Two or more diffusers are located near a bottom surface of the vessel. The diffusers are in communication with the air inlet and have two or more orifices through a wall. An adjustable plate is releasably mounted over the window of the baffle located closest to the far end of the vessel. The plate is adjustable in a vertical direction. In one embodiment, an air source supplies air to the air inlet located on the near end of the vessel. In another embodiment, an air source is connected to the an air exit located on the far side of the vessel.
