The sandglass shaped Kamizu Bubble provides a laminar flow, that ensures the floating bed to remain steady. By keeping the floating bed steady, all debris will be sifted out in the first (bottom) part of the floating bed ( = layer of beads). The highly effective beads, that have a useable surface of about 1300m2 per m3, can cope with a very high feeding pattern. Any captured dirt will quickly be removed through simply rinsing the system. The round-curved, sandglass shape ensures that there are no stagnation zones in the filter. The Kamizu Bubble filters very fine particles out of the waters. The removal of TSS (Total Suspended Solids) during one circulation of the pond water through the filter is:
100 percent of all debris of 50 microns and higher
60 percent of all debris between 20 and 50 microns.
50 percent of all debris between 5 and 20 microns. (1 micron = 0.001mm)
Pump / Energy One of the largest advantages of the Kamizu Bubble, in comparison to other beadfilters, is the required inlet pressure. On the Bubble one can use low pressure pumps, mostly being energy-saving pumps. Most other beadsystems need at least the double pump capacity to pump the same net amount of water through the filters. Therefore the Bubble is an energy saving beadfilter.
Pumpcapacity The pump capacity is related to the volume which a pump can deliver at a specific waterhead. The Head is generally recorded in meters or bar (1 meter Head being 0.1 bar). The beads themselves will cause a loss in pressure of approximately 0.01 till 0.05 bar (being a Head of 50 centimeters). Backwashing the system will cause a temporary increase of pressure loss over the filterbed.
Maximum pressure The Bubble itself has a pressurelimit of 0.7 bar. This limit may never be exceeded!
Resistance of pipes A low pressure pump, with a small Head is not suitable in case of longer pipes. The maximal efficient water flow should never exceed 1.5 meter per second. We strongly advise to keep the pipes as short as possible.
At a flow of 1.5 meter per second:
50 mm maximum 9 m3 per hour
63 mm maximum 15 m3 per hour
75 mm maximum 20 m3 per hour
90 mm maximum 30 m3 per hour
110 mm maximum 35 m3 per hour
Automatic Automating the Kamizu Bubble is probably the best way to ensure a good waterquality. The filter is then automatically rinsed at a fixed time. This way you will never forget to rinse your filter in those busy times; your pond is kept clean automatically.
The Kamizu Bubble: all advantages summed up:
An energy saving pump will do and therefore the Bubble is up to 50 til 80 percent more economic.
No external (extra) air pump needed for the rinsing process.
The surface of the beads is no less than 1300 m2 per m3.
The filter is very compact: A surface of 80x80 cm is sufficient for koi ponds up to 50.000 liters.
More effective debris removal due to the laminar flow through the medium.
Less protein, ammonia, nitrite, phosphate and nitrate, more oxygen in the pond.
Calm rinsing process prevents harming the biofilm while rinsing.
Less water consumption while rinsing.
Removes particles up to 5 microns (0,005 mm).
The filter bacteria work under optimal conditions, ensure efficient breakdown of ammonia and nitrite, even in heavily occupied ponds.
Very easy to control during the cleaning process.
Very easy to automate with optional automatic valve.
The filter can be placed both below and above water level.
The maximal resistance of the entire filter is less than 0.1 bar (1 meter Head)
Also suitable for swimponds and regular fish ponds.
The filter is the solution for both freshwater and seawater
The filter is made entirely of synthetic material
It is a static filter: therefore no moving parts that can suffer from wear and tear.
The filter uses LDPE beads, that comply to the requirements of the food industry.
Render time: 0.1252 sec, 0.0131 of that for queries.
