<p>A treating system having a horizontal zigzag flow type tank or a vertical zigzag flow type tank, wherein the interior of a chamber is partitioned by partitions in the horizontal or vertical direction to thereby provide a plurality of compartments being continuous in the horizontal zigzag fashion or the vertical zigzag fashion, and, in each of the compartments, a plurality of filter materials stand close together or lie down in parallel to one another. Or, a treating system having a combined up and down flow type treating tank, wherein a plurality of independent compartments which are connected to one another in such a manner that the matter to be treated is alternately and repeatedly treated and discharged from a final compartment by an up-flow or a down-flow, and, in each of the compartments, a plurality of filter materials stand close together. In the both treating systems, the filter material consists of a core material and a multiplicity of thin tape members made of synthetic resin radially exending around this core material. In addition, an automatic gas-lift agitator for agitating the matter to be treated in the tank with the use of methane gas produced in the tank may be connected to the system for improved treating efficiency.</p> |
