Kaldnes Miljöteknologi AS

Kaldnes, an environmental technology company that has developed an innovative, compact and flexible biological water treatment process, was the 2002 recipient of the Stockholm Industry Water Award.

The company’s patented Moving Bed Process makes wastewater treatment more efficient.

The Kaldnes Mijöteknologi Moving BedTM Process has benefited a diverse array of industries, enabled a world-wide business and knowledge network, and highlighted the unique collaborative opportunities between science and industry. Thanks to the technology, treatment facilities in the pulp and paper, pharmaceuticals, dairy, chemical and food industries, as well as municipalities, are smaller, more efficient at cleaning water, easier to build or upgrade, and more flexible.

Unique biofilm carrier
The core of the process is the biofilm carrier made from polyethylene with a density slightly below that of water. The carrier serves as a “home” for bacterial cultures, a catalyst for biological processes and can be applied in both aerobic and anaerobic conditions, and makes the technology feasible for all types of biological water and wastewater.

World-wide business structure
Today, Kaldnes licensees operate in over 20 countries, among those Australia, Brazil, China, India, Japan, Korea, and several countries in Europe. Kaldnes is operating through its own subsidiary, Kaldnes North America located in Providence, Rhode Island, in the North American market. An important part of the Kaldnes business strategy is the transfer of knowledge, experience and ideas among all the licensees and through that creating an effective network of exchange which is driving the solution development process.

Kaldnes, which is located in Tönsberg, Norway, is part of the Anglian Water group, whose head office is in Huntington, England. The process has been an important contributor to achieve the required 50% increase in reduction of nutrients into the North Sea that was agreed upon in the North Sea Treaty, signed in 1987.
