Abstract
PURPOSE: To dynamically filter a large quantity of water and obtain clean water in high speed, by providing an anthracite layer on a slightly coarse sand layer and by performing the filtration while back-washing away the clogging of the sand layer and stirring the anthracite layer.
CONSTITUTION: The anthracite layer 3' is stirred by the incoming water 6 ejected from an ejection stirrer 2' to maintain enough contact and apply adsorptive power to perform dynamic filtration. The upper portion of the static sand layer 4 under the anthracite layer 3' needs to be sometimes stirred to be prevented from getting clogged. To perform this prevention, water is introduced from a pipe 5 to cause the back wash. The above-mentioned treatment is effected while a water level WL1 is maintained. According to this method, a large amount of water can be rapidly filtered as an initial filtration speed is retained. This results in removing remaining solutes and providing clean water.
