Kaldness Biochip Media

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 have not been idle and they have continued their extensive Research and Development programme to further improve the efficiency of their process over the last 12 years.

The Bio Chip is the result of this programme and is much more than just 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 to K1/K3 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 will be flushed out.

These micro animals feed on small particles such as, fish waste, dead bacteria and algae. There are many different types of these micro animals that will colonize the media. Consider that Vortecilia are filtering 10,000 times their own volume per hour, and are feeding on particles up to 5 microns in size. It is these small particles that are always difficult to remove by mechanical means and make our water cloudy !
