Microporous Filter

Made from ultra-high molecular weight plastics or metal powders, the microporous filter elements are sintered using advanced techniques to create filter tubes. These elements are essential for various microporous filtration systems. Prior to shipment, every batch is tested for pore size, specific resistance, mechanical strength, and porosity to ensure compliance with quality standards.

The filter tank is designed with two sections: the main filtration zone and the bottom filtration zone. During normal operation, the material is filtered from the outside to the inside of the filter elements in the main filtration zone, with impurities trapped on the filter surface. The bottom filtration zone ensures that any remaining liquid in the tank is filtered, avoiding batch mixing between different production lots.

This product is widely applied in industries such as fine chemicals, pharmaceuticals, food processing, and new energy, where high batch consistency, large filter cake volumes, and strict dryness requirements are critical.

Working Principle

In the filtration process, slurry is pumped into the filter. The liquid phase of the slurry passes through the microporous filter tubes into the center of the filter elements, where it is gathered and discharged as clean liquid. Before a filter cake forms, the discharged “clean liquid” is recirculated back to the slurry inlet for further filtration until the filter cake reaches the desired level, ensuring that the filtration requirements are met. Once this point is reached, a signal stops the recirculation of the clean liquid, which is then directed to the next step of the process for normal filtration.

After running for a period of time, once the filter cake on the microporous filter tubes has reached a predetermined thickness, the system will automatically signal the stop of the feed. The residual liquid is drained from the filter, and the system then activates backwashing with compressed air, nitrogen, or saturated steam to detach the filter cake. After backwashing for a specified time, the backwashing process halts, and the discharge port is opened to expel the sludge. After the sludge removal process is complete, the discharge port is closed, and the system returns to its initial state, ready for the next filtration cycle.
