Abstract
PURPOSE: To obtain a complete cleaning effect by a simple operation in a short time by setting up the feeding linear velocity of liquid for back washing within a specific velocity range at the end of a granular filter medium and also the linear velocity of gas within a specific range.
CONSTITUTION: In a filter 12 having a vapor-liquid separation plate 9 for preventing the effusion of filter medium and a back-flow preventing plate 11, the linear velocity of cleaning water is set up within the range of 1/15W1/10 of the terminal speed in water of the granular filter medium of a filter medium layer 7, the linear velocity of air is within a range of 20W40m/h, and the time of back washing is at a value obtained from an experimental formula. After the completion of the filtering process, back washing is carried out only for hours set up each of simultaneous back cleaning with air and water and subsequent back washing with water. Thus, the withdrawal of water and back cleaning with air after the completion of the filtering process can be omitted and complicated opening and closing operations of valve can be eliminated, so that the time of back washing can be shortened and also the filter medium can be well fluidized, thus permitting sufficient washing effect to be obtained.
