ABW* Automatic Backwash Filter

Economical traveling bridge performance for municipal and industrial applications

The ABW Automatic Backwash Filter means economical traveling bridge performance for municipal and industrial applications. The low-head, shallow-bed design takes advantage of surface filtration to dramatically reduce construction and maintenance costs. Our exclusive seven-stage backwash process lets the filter remain on-line during cleaning for optimum performance without shutdowns.

Overview

The ABW Automatic Backwash Filter is suitable for tertiary treatment of municipal wastewater, potable water treatment, industrial water treatment, aquifer recharge, and water reuse, the ABW Automatic Backwash Filter is proven in thousands of installations worldwide.

Key features:

  • Shallow penetration and low driving head

    prevent solids from packing in media for easier removal.
  • Unique backwash design

    eliminates backwash storage tank, control valves, pipe gallery, surge storage, and large-horsepower pumps.
  • Low head operation simplifies

    basin and piping specifications for less expensive excavation and installation.
  • Regular, short-duration backwash

    reduces hydraulic loading rates for lower operating costs.
  • Carriage-mounted assembly

    is easy to inspect and service, and can usually remain on-line during maintenance.
  • Carefully controlled fluidization

    provides bed regeneration by eliminating solids breakthrough.
  • Title 22 Approved

QuickPlate

QuickPlate Filter Underdrain

Our ABW Quickplate Filter underdrain includes a unique, two piece cell design that virtually eliminates media leaks and offers increased strength, greater media-depth flexibility, and reduced maintenance. Easy to install, it directly replaces current configurations. 

  • Reduced risk of media leaks due to a strong positive seal and elimination of caulked butt or ledge joints and hold down angles. 
  • Increased underdrain strength through I-beam supported porous plates.
  • Easier installation because of a simplified grouting procedure and low profile bottom cell dividers. Fewer porous plates required.
  • Increased flexibility in media depth due to a bolt-in-top cell divider.
  • Direct replacement of existing design.
  • Reduced labor requirements.
