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 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 types of these micro animals as you can see in our close-up photographs. Consider that the Vortecilia 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 Bio Chip 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 Bio Chip is meant to be fluidized in conjunction with K1 or K2 media, and is an excellent addition to all Nexus filter systems . Add to existing moving bed systems in ratio of 25% of total media volume.

Bio Chips are sold in 25 liter bags (0.9 cf).

• The best biological medium available.
• Very firm and rigid.
• Never need to replace.
• Sinking.
• Dimensions 80" x 40" x 1.45"

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.

For best result, add 25% Bio Chips to the K3 media.

50 Liter bags = 1.77 cubic feet of media

MATALA Filtration Media is good for both mechanical and biological filtration.

• Even water flow throughout the filter media.
• Even adhesion of nitrifying bacteria to the filter mat's fibers.
• Very resistant against plugging by sludge build-up.
• Cleaning is fast and easy.
• Matala filtration media is weather and chemical resistant.
• Matala filtration media is easily cut.
• The various densities of Matala can be used in sequence or separately for unique filtration requirements.

Savio Springflo Bio-Filter Media is a polypropylene and calcium carbonate ribbon.

The embossed diamond pattern of the Savio Springflo creates millions of dimples to rapidly secure and develop bacteria. Easy to use and maintain, inexpensive, and resists channeling, clogging, and compaction in up-flow and horizontal flow environments.

180 square feet of surface area per box. Fills 2-3 cubic feet.

Each box is enough to filter approximately 1000 gallons.
