1. Brush-Type Self-Cleaning Filter: “Filter and clean simultaneously — impurities removed on the spot.” Its core design features a single filter element with an internal rotating brush, which works like an “automatic toothbrush” for the screen. During operation, the unfiltered liquid passes through the filter…

Choose a Self-Cleaning Filter if your operating conditions meet any of the following: The impurities are sticky or oily, such as biological slime in circulating cooling water, oily wastewater, paper pulp, or food processing wastewater. High filtration accuracy is required, typically below 100 μm. System…

When selecting filtration systems, it is important to understand the differences between self-cleaning filters (brush or suction type) and traditional backwash filters. The following comparison highlights the key distinctions: Cleaning Method Self-cleaning filters utilize mechanical brushing or suction to remove impurities, whereas backwash filters rely…

Fundamental Difference: Completely Different Working Principles Although both are called “automatic filters,” their cleaning mechanisms are essentially different. 1. Working Principle of a Self-Cleaning Filter Cleaning Mechanism: Mechanical brushing + discharge. A motor drives a brush or scraper to physically remove impurities attached to the…

An automatic backwash filter is a self-cleaning filtration system designed to ensure continuous operation. When impurities accumulate and the inlet–outlet pressure differential reaches the preset value, or after the set time interval, the control system automatically initiates the cleaning process. Main Features Zero downtime maintenance…

The selection of an automatic backwash filter should be based on the medium type, flow rate, pressure, and other parameters. Details are as follows: Medium Type Examples: fresh water, seawater, lubricating oil, etc. For seawater or corrosive media, stainless steel or copper-nickel alloy materials are…

Brief Description of Operation Steps of Automatic Backwash Filter: Filtration Stage: The medium flows in from the inlet, passes through the filter element, and impurities are retained while the clarified liquid flows out. Differential Pressure Monitoring: When the pressure difference between the inlet and outlet…

Marine Automatic Self-Cleaning Filter is widely used in marine cooling water systems (especially when seawater is used as the cooling source), ballast water systems, and lubrication oil systems. Its purpose is to filter out particulate impurities from the medium, while performing automatic online backwashing to…
