Bubble Bead Filters BBF XS1, XS2 & XS4 Range

Bubble Bead filters are unique in design; water is pumped through the inlet and the inlet screen flowing up through the floating bead bed where the filtration takes place.

Bubble bead filters work both mechanically removing particles down to 10 micron and biologically breaking down waste products to provide high standards of water quality.

This unit can also be placed in line with ancillary devices or it can be used to back up an existing filter system.

Backwash: On Manual models(XS1 & 2), the control valve is simply turned to 'waste' and the backwash process starts. On Hydraulic Valve models(1.5,3,5,7 & 9), the backwash starts automatically when the pump is turned off. The one-way air inlet valve opens automatically as the waste water starts to flush out of the waste outlet. The Bubble Wash process begins. The beads tumble clean in a cascade of air bubbles and dirt is drawn out through the screen as water leaves the filter by gravity.

After the Backwash: On Manual models, the control valve is turned to 'run' and the filter starts to refill. On Hydraulic Valve models, once the pump is restarted, a final short rinse of the waste pipe work takes place, then the waste outlet closes automatically and the filter starts to refill.

Once the filter has refilled, filtration continues as normal until the next backwash.

Hydraulic Valve System (BBF-1.5/3/5/7/9)

In this patented valve system the backwash is controlled automatically by simply turning the pump on or off. Simply wire the pump through an appropriate timer for a fully automatic backwash. No expensive solenoid valve is required.
