Deep Bed Filtration

Fiber Bundle
Filter Media

Fiber bundle filter media is a micron-grade filter material: fine fibre strands are gathered into a bundle and hung on a support frame inside the filter. Under downflow the bed compresses, so its pore size closes along the flow path and suspended solids are held through the full bed depth. Under air–water backwash the bundles open again and release what they captured.

Why this media

Micron-grade filtration,
a bed that reopens

The media replaces millimetre-scale filter grains with fibre strands tens of micrometres across, and keeps them in an ordered bed that is compressed to filter and loosened to clean.

Micron-grade interception

Because the strands are 20–50 µm across, the filter surface area reaches up to 3500 m²/m³ — far beyond what a granular bed of the same volume can offer — so suspended solids that a millimetre-scale filter grain lets through are intercepted instead.

A bed that grades itself

Under downflow the density-adjusting device drives the fibre bed downward, so packing density rises and the pore size falls along the flow path. The result is a graded, variable-pore deep bed without the artificial media grading that granular filters need, holding up to 8 kg/m³ of solids.

Fast, complete backwash

On air–water backwash the bed lifts and the bundles open up, so the solids held through the bed depth are washed out in a short cycle. The bundles stay hung in order, do not knot or wash out, and the run can be automated.
