Kaldnes Filter Media - Nexus Eazy
 Since the development of the Kaldnes Moving Bed process and its
successful introduction into the waste water treatment industry in 1991, Kaldnes K1 media has become the industry standard throughout the
world.
However Kaldnes has not been idle, as they have continued their extensive
research and development program to further improve the efficiency of their process over
the last 12 years.
The main difference is that the protected area or quiet zone in the
BioChip is designed to be the perfect environment for micro animals, not just
bacteria. The extremely quiet zones created by the hydrophilic layer protecting
every cavity in the BioChip is critical to allow these micro
animals to flourish. With other types of media, they will be flushed
out.
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.
Kaldnes
K3 media
Kaldnes
K3 media is similar in application to Kaldnes K1 media, in that the constant chaotic
movement of the air from your pump causes the media to self-clean and thus requires no
maintenance. K3 media is different than K1 media, as it is designed to be used in
the retrofitting of existing filters bays as the slightly larger media size allow for
easier configuration and control.
How it works
:
Maturing the Kaldnes bio-media is important because a
delicate eco-system is naturally developing for the bacteria involved in the nitrification
process. Kaldnes media provides the maximum active surface area for the bacteria to
colonise, more than other types of static media. It is this process which removes harmful
ammonia and nitrite from the water.
How it is different to other
media :
As the Kaldnes media moves within the filter, it causes the old dead
bacteria on the outside to be displaced. This makes space for new younger heavier feeding
bacteria to rapidly colonise. Within the wheel is a protected surface which enables
colonies of bacteria to naturally follow their lifecycle, of maturing, dying and then
fueling the latter stages of the nitrification cycle. Kaldnes has been designed to provide
the best possible habitat for both young and mature beneficial bacterial
colonies.
