Name: Tubular Filter
Brand: JX Filtration

Description

JX Filtration offers a full range of tubular filter housings from single-tube to multi-tube models, with flexible customization options to suit various flow rates and filtration needs across industrial, commercial, and specialized applications—reliable, efficient, and fully automated.

A tubular filter, also known as a tubular backwash filter or multi-tube self-cleaning filter, is a mechanical filtration device that uses multiple parallel filter tubes arranged inside a housing as the filter medium. Each filter tube is fitted with a filter medium such as wedge wire screen or sintered mesh. The tubular self-cleaning filter has shown excellent application value in many fields such as petrochemicals, papermaking, and water treatment. With high-precision filtration, fully automatic cleaning, and low maintenance cost, tubular filters are widely used in various industrial process applications.

Working Principle

The tubular filter operates through two alternating phases—filtration and backwashing:

Filtration Stage: Liquid enters the housing and flows through the multiple parallel filter tubes arranged inside. Dirty liquid flows from the outside of the filter tubes to the inside, with solid particles retained on the filter medium surface, and finally flows out from the liquid collection cavity of the filter. The parallel arrangement of multiple tubes provides a large filtration area within a compact footprint.
Backwashing Stage: The control system adopts differential pressure and time-based control (with differential pressure priority). When the pressure difference between the inlet and outlet reaches the preset limit, the filter automatically enters the backwashing process. The filter tube unit that needs cleaning stops filtering and performs backwashing, while other units continue normal operation. The entire cleaning process is controlled by a Siemens PLC integrated with a touch panel, enabling 7×24 hours of unattended operation.

Advantages

High filtration precision: Can achieve filtration precision as low as 1 micron even under high flow conditions
Large filtration area: Multiple filter tubes arranged in parallel provide extensive filtration surface within a compact housing
Fully automatic operation: Siemens PLC system with DP & time-based backwashing for unattended operation
Modular and expandable: Can freely increase or decrease the number of filter elements according to different working conditions
Continuous operation: Backwashing occurs without interrupting the main flow, ensuring uninterrupted production
Thorough cleaning: Backwashing and filtration can be carried out simultaneously
