USCF Series Automatic Self-Cleaning Filter with PLC Controller and Wedge-Wire Screen

Self Cleaning Filter

High-Performance Automatic Backwash Filtration Solution

The CMI USCF Series Self Cleaning Filter is a high-performance automatic backwash filtration system designed as a cost-effective alternative to expensive traditional filtration systems.

Engineered for continuous industrial operation, the USCF series ensures zero interruption to flow during its rapid cleaning cycle, which is typically completed within 12 seconds.

The system utilizes a durable stainless steel wedge-wire screen combined with a smart PLC controller, providing reliable automatic filtration from 10 μm to 4,000 μm.

With flow capacities up to 4,000 m³/hr and a clean pressure drop of less than 1 psi, the USCF series is ideal for demanding industrial applications including cooling water, seawater intake, recycle water, and wastewater pretreatment systems.

Filter bodies are available in SS304, SS316, or ETFE-coated carbon steel, providing long-term durability and corrosion resistance in harsh industrial environments.

By automating the cleaning process through differential pressure monitoring and PLC-controlled flushing, the USCF series delivers a true zero-consumable filtration solution, significantly reducing manual maintenance and long-term operating costs compared to conventional bag or cartridge filters.

Automatic Backwash Filter for Process Water & Industrial Applications
The CMI USCF Series Self Cleaning Filter is designed as a cost-effective alternative to more expensive automatic filtration systems, providing continuous filtration, low maintenance, and reliable performance for water and industrial liquid applications.

This automatic backwash filter is suitable for process water, cooling water, sea water, recycle water, wastewater pretreatment, and selected high-pressure or high-temperature applications.

The USCF system is equipped with stainless steel wedge-wire screens, a PLC controller, a differential pressure switch, and a high-efficiency flush valve. For larger flow requirements, multiple units can be installed in parallel.

Filter bodies are available in SS304, SS316, or carbon steel with ETFE coating, ensuring durability in demanding industrial environments.

With a 100 μm screen, clean filter pressure drop is typically less than 1 psi at rated flow.

Key Features

✔ Cost-effective automatic filtration solution for water and low-viscosity liquids
✔ Continuous filtration during cleaning with no interruption to flow
✔ Fully automatic operation with minimal manual intervention
✔ Low clean pressure drop (<1 psi at rated flow with 100 μm screen)
✔ Modular and scalable design for single-unit or parallel installation

Working Principle

The USCF self-cleaning filter consists of a heavy-duty filter vessel, two filtration stages, a flush valve, a differential pressure switch, and a PLC controller.

Filtration Process

  1. Unfiltered liquid enters the vessel and first passes through the coarse screen.
  2. The liquid then flows through the fine screen where smaller contaminants are retained.
  3. Clean liquid exits through the outlet with minimal pressure drop.

Automatic Cleaning Cycle

  • Differential pressure increases as solids accumulate
  • Pressure switch sends signal to PLC controller
  • Flush valve opens automatically
  • Reverse flow removes contaminants from screen surface
  • Captured solids are discharged within seconds
The cleaning cycle is completed in less than 12 seconds while filtration continues without shutdown.

Applications

  • Industrial process water
  • Cooling tower water filtration
  • Sea water intake protection
  • Recycle water loops
  • Wastewater pretreatment
  • Steel mills and paper mills
  • Municipal and industrial water treatment
  • Irrigation systems
  • RO and UF pretreatment
