Spiral filter |
| abstract |
(57) [Summary] [Purpose] A spiral filter that can dramatically improve the filtration ability and durability as a filtration material and stabilize the purification treatment ability of the wastewater treatment method by iron-oxidizing bacteria at a high level. Providing materials. [Structure] Outer edge 1a of a plastic fan-shaped plate Is continuously folded back into a substantially S-shaped 1b, and the folded side A formed into a folded shape is twisted a plurality of times with the inner end side 1c of the substantially fan-shaped plate material as the center side to form the entire shape. It has a spiral configuration. |
