Filter Ag

Clack Filter-Ag is a high-performance granular filtration media engineered for the reduction of suspended solids and turbidity in residential and commercial water systems. Its uniquely fractured edges and irregular surface create a remarkably high surface area and a complex internal flow path, allowing it to capture particles throughout the full depth of the filter bed rather than only at the surface. This deep-bed filtration is what sets it apart from ordinary media and makes it a longtime favorite among water-treatment professionals who deal with cloudy, sediment-laden, or turbid water supplies.

Why Filter-Ag Outperforms Sand

Because the particles are large and irregularly shaped, sediment penetrates deep into the bed instead of caking on the top few inches the way it does in a conventional sand filter. That difference prevents the rapid buildup of head loss and the blinding problems common to sand, so you get lower pressure loss, higher sediment-holding capacity, and noticeably longer filter runs between backwashes. Typical performance reduces suspended matter down into the 20-40 micron range, delivering clearer water with less maintenance and less downtime for cleaning the bed.

• Reduces suspended solids and turbidity, typically into the 20-40 micron range
• Lower pressure drop than most other common filter media
• Lightweight design allows lower backwash rates and better bed expansion
• High sediment loading capacity for longer service runs and real water savings
• Effective at trapping oxidized iron flock after aeration, ozonation, or chlorination
• Supplied as a 0.75 cubic foot quantity weighing approximately 22 lbs

Filter-Ag works in both pressure and gravity systems and can be incorporated into multi-media, graded-density beds for the most difficult filtration challenges, giving designers a flexible tool for tough water. Its light apparent density also lowers handling and shipping demands, and replacing sand with Filter-Ag in an existing installation can increase filter capacity substantially while reducing the backwash water required. When commissioning a new bed, take care during start-up that the lightweight media is not flushed to drain, and configure your control valve for the proper backwash flow rate so the bed expands fully and rinses clean each cycle. Maintained correctly over its service life, Filter-Ag delivers years of efficient, water-conserving filtration that keeps treated water clear and downstream equipment protected from grit.
