Abstract

PURPOSE: To automatically wash the filter layer with a sinple construction counter, by providing the draft tube in the filter bed and sending compressed air, at the time of filtering by the upward flow using floatable lightweight particle as filter material.
CONSTITUTION: Feed liquid is passed in upward flow through the packing bed 7 formed the filter medium having a lower specific gravity than that of the filter feed liquid, under maintaining board, such as the perforated plate 6, provided with the upper part of apparatus and is filtered. When the pressure loss is made great in the filter bed by an increase of filter residual substrance of growth of microorganism film, feeding of the feed water is stopped and compressed air is sent to the draft tube 5 opening the upper end under the upper face of the filter bed and the lower end near the bottom face. Thereupon, the whole liquid in the apparatus is turned into circulating flow and the microorganism layer stuck on the filter medium, is exfoliated and caught SS, etc. are released during the circulation and then, counter washing is carried out. Thus, the filter medium is automatically washed counter by a simple construction and the counter washing water can be economized also.
