Horizontal rod-supported, pore-controllable fiber media filter, and horizontal rod-supported fiber filter system

A horizontal rod-supported, pore-controllable fiber media filter comprising:

• a fiber support comprising fixing supports to stand at both sides thereof and a plurality of horizontal rods which are coupled rotatably to the fixing supports in a zigzag pattern at intervals in a lengthwise direction of the fixing supports;
• a fiber media which hangs on the horizontal rods of the fiber support in a zigzag pattern, in which the lower end of the fiber media forms a fixed end attached to the lower end of the fiber support, and the upper end of the fiber media forms a free end at the upper end of the fiber support;
• and
• an actuator which is coupled to the free end of the fiber media to pull or relax the fiber media supported by the fixed end,
• the fiber media filter being configured such that, when the actuator is driven to pull the fiber media, the fiber media forms filtration pores while being supported by the horizontal rods of the fiber support in a zigzag pattern,
• when the actuator is driven to relax the fiber media, the fiber media is relaxed in a zigzag pattern to form backwashing pores,
• the filtration and backwashing capacities of the fiber media filter are determined by the horizontal intervals, and
• the rotatable coupling to the fixing supports absorbs a frictional force, which is caused by the pulling and relaxation of the fiber media, and transforms the force into rotational motion.
