    摘要: A method is described to remove condensible vapors in highly compressed gases without affecting the original particle spectra and concentrations. The vapors are separated from particles primarily through diffusion mechanism and collected on cold surfaces. Four important parameters are the length, the flow rate, the temperature, and the diffusion coefficients of the vapors to be removed. Important applications include sampling particles from high pressure gases and condensible vapor-free filling for ultra-pure cylinder gases.

    摘要: A method of cleaning a reverse osmosis or nanofiltration membrane includes supplying pulses of bubbles to the membrane. A venturi device for supplying bubbles to improve the cleaning of reverse osmosis or nanofiltration membranes includes a venturi having a liquid inlet and an air inlet provided at a choke point of the venturi, as well as an outlet. The air inlet is provided with a plurality of tubes. A reverse osmosis plant includes a membrane pressure vessel having a fluid inlet, a permeate outlet, a concentrate outlet and an in place cleaning tank connected in line with the fluid inlet. A venturi valve is connected in-line between the cleaning tank and the fluid inlet.
