The disc filter is composed of filter units juxtaposed, and the filter unit is mainly composed of a group of ring-shaped reinforced plastic filter discs with grooves or ribs. When filtering, the sewage enters from the outside, and the rim formed by the edge of the groove on the adjacent filter disc intercepts the solids in the water; when backwashing, the water flows from the inside of the annular filter disc to the outside, and the dirt trapped on the filter disc is removed. Rinse down and discharge through the drain.

The unique structure of the filter disc also makes the backwashing process of flushing out the dirt simpler and easier, without the need for complicated mechanisms such as motors and drivers, and simple water flow is enough to flush the dirt out of the filter element. This excellent performance reduces the backwashing time of the filter; at the same time, because the dirt is not only stored between the filter disc set and the shell, more can be stored inside the filter disc set, so the filter can hold more dirt.

The disks are tightly compacted and stacked together in the unit, and the grooves in the middle of the upper and lower layers of disks play the role of filtering and intercepting.

The disc filter is designed with ribs of different structures on both sides of the filter disc. These ribs are stacked together to form an intercepting surface. Among them, the curved ribs mainly play the role of intercepting and storing suspended solids. The slightly larger opening design on the outside can ensure backwashing There is no need to loosen the filter disc during operation, and a thorough backwashing effect can be achieved even when the water pressure is low; the ring-shaped edge determines the filtration accuracy and constitutes a water channel, and the filter disc can provide a filtration accuracy of up to 5μ.

It is a kind of self-cleaning filter. It adopts a number of patented technologies. It is safer and more efficient to install and use, saves water, land and less daily maintenance.

The filter element has no spring design, and the water pressure is cleverly used to compress the disc set when filtering, so that the pressure requirement for backwashing is greatly reduced.

The unique built-in duckbill valve ensures the maximum water output of the filter element during filtration, and at the same time plays a very good backstop function during backwashing.

The split-assembled filter element framework can flexibly adjust the height of the filter element according to the design requirements, so as to achieve the function of adjusting the filtration area and meet the matching requirements of different systems.

Abandoning the commonly used metal clamp design, the filter unit adopts a self-locking buckle and a specially designed sealing ring. The installation and disassembly of the filter unit shell is simple and easy, and the sealing effect is good.

Each filter unit is equipped with a filter and backwash status indication device and an automatic exhaust device, which can improve the backwash effect of the filter element while avoiding water hammer damage.

When the raw water passes through the filter unit, it flows from the outside to the inside, and the impurities larger than the groove will be intercepted outside.

The core component of the disc filter is the stacked plastic filter discs. There are special grooves or ribs on the filter discs. The grooves or ribs on the adjacent filter discs form a channel of a certain size. The particle size is larger than the channel size. The suspended solids are all intercepted to achieve the filtering effect. This product can largely replace traditional mechanical filtration devices such as sand filters, with superior performance and much lower water and electricity consumption than other products.

When the raw water enters the middle of the two filter discs, it first flows into the disc along the curved edge, but it cannot enter directly after careful observation. At this time, it is the annular rib that plays the role of filtering and intercepting. The impurities smaller than the groove size of the annular rib can enter the curved rib connected with the interior along the annular rib, and the large impurities are intercepted.
