    摘要： A method and apparatus for removing impurities from a liquid by passing the liquid through a filter bed comprising a mixture of treated filter aid material and an active particulate material. The filter bed is produced by blending a mixture of filter aid material, active particulate material and an electrolyte-type compound that produces a surface charge opposite to the normal surface charge on the filter aid material in the presence of water so that the total solids content is greater than 20 percent during the blending of the mixture.

    摘要： This invention involves a method of stepwise oil-water separation by oil-gas washing in Fischer-Tropsch process. At first, after mixed washing and hydrocarbon composition, light oil containing about 0.5-6% synthetic water and low gas containing trace hydrocarbon enters from the left-side end socket into the primary oil-water separator, and sewage containing 0.05-0.5% oil enters into the separator from the right-side end socket; purified low gas is discharged from the top and the mixed liquid enters into in-depth dehydrator after being discharged. Discharged light oil contains about 0.05-0.5% of water; sewage on the left side is discharged after entering water drum and sewage after deoiling on the right side is discharged on the right side of clapboard and enters into in-depth oil eliminator. Discharged oil contains about 0.03-0.6% water; after in-depth deoiling and dehydration through conjugate fiber module weaved in particular form in in-depth dehydrator and oil eliminator, light oil containing less than 0.02% water and sewage containing less than 0.01% oil are discharged separately. The method of combined oil-water separation and stepwise separation provided by this invention is able to make fast and efficient oil dehydration and sewage deoiling, and to recycle oil to the maximum extent.

    摘要： The present invention relates to a porous media-mediated high speed filtration device for easy backwash, wherein the inflow water to be filtered is guided to an upper portion of the high speed filtration device and is filtered by downflow and porous media are backwashed for maintaining optimum filter efficiency by blocking the flow of inflow water and water to be treated after sensing the level of the inflow water or the change in the flux of the water to be treated, supplying backwash water and/or air by upflow through a backwash equipment to separate pollutants in the porous media by the collision and friction between the porous media by flowing of the porous media through the stream of the backwash water, placing the porous media in a stationary location, and discharging the pollutants through a discharge pipe of the high speed filtration device before the pollutants settle. In addition, the present invention comprises a backwash method of the high speed filtration device using porous media.
