Koi Pond Filtration » Bubblebead BBF Filters » Bubblebead BBF Filters

Bubblebead BBF filters were designed for use in tropical fish breeding systems where a filter capable of solids capture and biofiltration was needed to support high densities of fish. Disease isolation was considered critical so the individual units were designed to operate on airlift and all were cleaned by a central vacuum. This reduced the labor and protected the fish from rapid disease spread.

Bubblebead BBF Beadfilters function both as a solids capture device and a biofilter. They operate very much like a submerged rock bed or undergravel filter except that they are designed to facilitate cleaning.

BubbleBead BBF filters feature patented technology and their proven loading rates are based on university research and many years of practical use in the aquaculture industries.

The versatility of BubbleBead BBF filters has made them a leading choice for new installations and upgrades to existing systems where high loading capability and good water clarity are paramount.

Bubblebead BBF Key Features:

• Biological and mechanical filtration in one unit
• Sparkling water clarity
• Removes fine solids to below 15 microns
• Highly efficient breakdown of wastes
• Massive effective surface area of special bead media for biological activity
• Flushes wastes away in minutes without upsetting biological activity
• Air-suction design - NO air blower required

Normal Running

• Water is pumped up through the bed of floating beads
• The beads pack tightly to filter out fine solids
• The massive surface area of the beads supports beneficial bacteria that break down fish waste

Backwash

• On Manual models, the control valve is simply turned to ‘waste’ and the backwash process starts.
• On Hydraulic Valve models, 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 BubbleWash process begins. The beads tumble clean in a cascade of airbubbles 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 pipework 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
