Modular Self-Cleaning Filter

Product Introduction

The modular self-cleaning filter is a cutting-edge filtration solution designed to combine multiple standard filtration units into a single, fully automatic system. This modular concept offers flexibility and scalability, allowing users to expand filtration capacity by adding more units as needed. The system is fully automated, significantly reducing maintenance and manual cleaning requirements. With a high safety factor and the ability to connect high-pressure backwash fluids, it is ideal for various applications involving low-viscosity liquids.

Working Principle

Water or liquid enters the filter through the inlet and passes through the V-SLOT filter element, which captures suspended solids and impurities. The clean liquid exits through the outlet, while particles accumulate on the inner surface of the filter element. When the pressure difference reaches a preset value, the control system initiates the backwashing process.

During backwashing, high-pressure backwash fluid flows in the reverse direction through the V-SLOT filter elements. This thorough cleaning method minimizes liquid consumption and ensures the continued efficiency of the filtration process. The modular structure allows for flexible expansion and the addition of online units based on changing flow requirements.

Material Composition

The modular self-cleaning filter is built with high-quality materials to ensure durability and performance:

• Filter Housing: Stainless Steel (SS304/SS316L) or Carbon Steel with Anti-Corrosion Coating

• Filter Element: V-SLOT Stainless Steel Wedge Wire

• Control System: Automated PLC System for precise operation

• Backwash Fluid Connection: High-Pressure Resistant Components

• Modular Units: Easily connected through flange or threaded joints

• Seals and Gaskets: NBR, EPDM, or PTFE for leak prevention

Applications

The modular self-cleaning filter is suitable for various industrial processes requiring continuous filtration of low-viscosity liquids:

• Water Treatment Plants: Raw water and wastewater filtration

• Petroleum Industry: Gasoline, diesel, and residual oil filtration

• Chemical Processing: Removing particles from chemical solutions

• Cooling Water Systems: Maintaining clean recirculating water

• Food and Beverage Industry: Filtering process water and ingredients

• Marine Applications: Filtration of ballast and cooling water

Key Selection Parameters
