 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 BioChip is the result of this program and is much more
than simply a different shaped media. Although the total protected surface area is
more than 2.4 times higher than K1, this is only part of the story.
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.
These micro animals feed on small particles such as fish waste,
dead bacteria and algae. There are many types of these micro animals as you can see
in our close-up photographs. Consider that the Vortecilia (reference fig 1) are
filtering 10,000 times their own volume per hour and are feeding on particles up to 5
microns in size! Once fully colonized, the BioChip contains an army of these micro
animals, all filtering tens of thousands of times their own volume every hour. The
result - gleaming healthy water, high in oxygen content and low BOD will follow.
The BioChip is meant to be fluidized in conjunction with K1 or K3 media, and is an
excellent addition to all Nexus filter systems (reference fig 2). Add to existing
moving bed systems in ratio of 25% of total media volume. Click here to learn more

BioChips are sold in 25 liter
bags (0.9 cf).

The main difference to K1 is
that the protected area or quiet zone in Bio Chip 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 Bio Chip is critical to allow these micro
animals to flourish. With other types of media they tend to be flushed
out.
Add to existing
K1/K3 moving bed in ratio of 20 % to total media volume, 1 part Biochip to 4 parts K1/K3,
so just to confirm 25litres of Biochip to every 100 ltres of K1.
These micro animals feed on small particles such as fish waste, dead bacteria and algae. There are
many different types of these micro animals as you can see from our illustrations.
Consider that the Rotifier as illustrated above is filtering 100,000 times its own volumes
per hour and is feeding on particles up to 10 micron in size. It is these small particles
that are always difficult to remove by mechanical means and make our water cloudy !
