BEADFILTER OPERATION

Water enters into the tank (A) under pressure from the pump. The solids are collecting in the centre of the lter, waiting to be
hydraulically purged out under pressure from the pump. All you have to do is open the sludge separation valve (B) with the
pump running and the lter in it's normal ltration mode and the heavier solids are evacuated in just a couple of seconds.
What does all of this mean? The most unique, e cient lter of its kind. An e cient lter doesn't hold solids, it gets rid of them!
Now that the water is in the tank it is forced slowly upward in the vessel through millions of beads about 3-4mm in size. On
these beads are billions of nitrifying bacteria and these hungry bacteria are consuming vast amounts of ammonia, nitrites, etc.
and performing what is known as nitri cation. This is how we actually have clean, healthy water is due to the work these
microscopic organisms are performing. Water continues to ow upward through the beads and exits out of the vessel via the
top spray bar (C). This water then continues back to the pond/biopool.
The UltraBead® series have another unique feature: the Blower (D). This blower is mounted on a special air check valve. It is
important that the valve be in the rinse position for the blower agitation of the beads. When the blower is active the beads
and debris are dispersed throughout the interior of the lter. This breaks up the beads and releases the trapped particles. This
debris then can easily be backwashed out to waste through the spray bar (C). After the RINSE cycle with air we perform a
backwash in which the water enters at C en leaves the lter through A. After the backwash there will be another RINSE cycle
but with water instead of air. This takes any remaining debris and sends it to waste (from A to C), instead of sending a cloud of
dirt back to the pond. You can nd the full details on backwashing the lter on page 7 & 8.
BACKWASH FREQUENCY
For ponds with sh (koi) it is recommended to clean the lter once or twice per week during the feeding season.
For swimming ponds/biopools it is recommended to clean the lter once per week or once per 2 weeks during the swimming
season.
