Backwash Demo of Bubble Bead Filter – Robust, dependable filtration for ponds.
Bubble differs from the Propeller Bead® and Polygeyser® bead filters in its simpler, yet very effective gentle backwash. The backwash is started by shutting off the circulation pump and opening the sludge valve. As the water drains from the filter, a check valve on the effluent line closes, creating negative pressure in the filter. The potential energy of the water leaving the filter pulls air in through the air inlet. Expanding and agitating the bead media in a vigorous boiling type action as it passes downward through our unique washing throat.
As the beads enter the lower expansion chamber, the downward velocity decreases due to the increased cross sectional area so the beads are suspended as the water washes the solids away from the beads and out of the filter. Once the flow of the wastewater stops, the backwash is complete. Simply close the sludge valve and turn the circulation pump back on. Your filter is now in normal operation with a clean filtration bed.
