Description

Technical Field

[0001] This utility model belongs to the field of water filtration technology, and specifically relates to a water supply and drainage filtration device. Background Technology

[0002] Water supply and drainage filtration devices are used to treat water supply and wastewater. Their main function is to remove impurities, particulate matter, and pollutants from the water to ensure that the water quality meets usage or discharge standards. These devices include various filter screens, filter cartridges, sand filters, activated carbon filters, and membrane filtration systems. They are widely used in domestic, industrial, and municipal engineering projects. Filter screens, cartridges, and activated carbon filters can become clogged with contaminants after a period of use and require regular replacement. If replacement is not timely, the filtration efficiency will significantly decrease. Long-term use leads to equipment wear, especially in mechanical parts, which are prone to damage and require regular inspection and maintenance. The conventional approach is to hire professional technicians to operate and maintain the system to ensure efficient operation. However, this method increases labor costs and relies heavily on technical personnel. Therefore, a new structure is proposed to address these issues. Utility Model Content
