Incorporating Kaldnes Moving Bed™ Process
Kaldnes Moving Bed™ process, which has been scientifically
tried and tested in fish farming and waste water treatment for
over 10 years, is now available to fish keepers and is exclusively
distributed worldwide by Evolution Aqua.
Developed by Professor Halvard Odergard at Trondheim University
of Science and Technology the Kaldnes Moving Bed™ bio film
process has been designed specifically to create the most effective
environment for the nitrification process to take place. The
media is engineered in a wheel shape and is slightly positively
buoyant, allowing a small amount of water flow (created by adding
air to the process) to circulate the media throughout the vessel.
Oxygen and food (ammonia and nitrite)
gives the bacteria the means to grow, whilst the Kaldnes media
provides maximum surface area for the bacteria to colonise and
produce bio film. It is this process, which removes harmful ammonia
and nitrite from the water. As the Kaldnes media chaotically
circulates within the bio tank, it causes old dead bacteria/bio
film on the outside, to be removed making space for new younger
heavier feeding bacteria/bio films to colonise. Within the wheel,
is a protected surface, which enables colonies of bacteria to
naturally follow their life cycle, maturing and dying, in turn
fuelling the latter stages of the nitrification conversion process.
It also assists in the breakdown of any small particles passing
through from the mechanical stage. Therefore, the Kaldnes media
maintains both a young bio film and a maturing bio film providing
a more consistent filter performance, whilst improving water
quality, encouraging healthier Koi and aiding in reducing
green water and blanket weed.
Due to chaotic movement of the Kaldnes K1 media, the process
is self-cleaning and requires no maintenance. This allows the
filter to reach optimum effectiveness without the disturbance
of periodic maintenance, avoiding unnecessary loss of bacteria
within the filter preventing high levels of ammonia and nitrite
within the water.
