So far, the laminated filter has been widely used in industrial and commercial fields. Such as HVAC systems in commercial, architectural, industrial, papermaking, building materials, pharmaceutical, plastic, metallurgical, textile, food and other buildings, wastewater treatment, irrigation, sewage recycling, waterworks, water supply, chemical enterprises, large power plants. And in fields such as emergency filtration. The filtration grade of the disc filter can be determined based on the water quality requirements of the water system and equipment as well as the water quality requirements of the water usage site. Next, the author will talk to everyone about disc filters. Its working principle will help everyone better understand this type of filter.

When the water flow in the disc filter enters the equipment through the water inlet of the filter, Under the action of the intervening spring force and the water pressure in the filter disc, they can be closely adsorbed together, causing the impurity particles to be retained at the intersection of each section. The water passing through the disc filter will flow out from the main channel, and at this time, the one-way diaphragm valve will be in the open state. As a filter carrier for impurities, the filter core and filter plates of the laminated filter in the electrolytic water treatment instrument are composed of a set of plastic discs superimposed. There are grooves in different directions on both sides of the disc, and the edges of the grooves on adjacent surfaces can form countless intersection points.

These intersections can form a large number of voids and some irregular channels, which continuously decrease from the outside to the inside. During the filtration process, these channels cause turbulence in the water, which will prompt the interception of impurities contained in the water. And take the disc over the intersection. For example, by stacking the discs on the filter element frame. A filter unit that is loose on the outside and tight on the inside can be formed by the pressure of pure water and a spring.

In each filter unit, laminated materials compressed by springs and water pressure form numerous filter screens, preventing foreign particles from passing through. The lamination width is 12 to 14 millimeters, and the lamination material is high-quality engineering plastic. It has extremely high wear resistance. Supported by stainless steel springs, it has a solid structure. The backwash water flows along the tangential direction of the inner wall of the laminated plates. From the inside out, all kinds of impurities adhering to the surface of the laminated plates are washed away. Under the action of the backwash water flow, the laminated plates rotate. Ensure that all dirt is effectively rinsed and discharged. Time intervals and pressure differences can be used to control all steps of backwashing.." Once set, it can be used for a long time. The automatic backwashing filter can complete the entire automatic backwashing process within a few seconds without interrupting its operation. A filter that adopts this filtering principle. During filtration and backwashing, the layering gap can be dynamically adjusted, which is highly beneficial for enhancing filtration performance and water quality, and can significantly reduce the water consumption for backwashing.."
