Aquaculture References Municipal & Industrial References Previous 1/9 Next OUR STORY The story begins in 1985, when Professor Hallvard Ødegaard at the Norwegian University of Science and Technology (NTNU) started researching a new idea for cleaning water. Prof. Hallvard Ødegaard The result of his extensive research was a new technology for processing wastewater called Moving Bed Biofilm Reactor (MBBR). Today Kaldnes MBBR is one of the most advanced biological processes for cleaning wastewater and one of the most significant environmental success stories in Norway. Throughout the years, we still have close contact with established research environments such as (NTNU) in Trondheim. Patent, awards and acquisitions In Tønsberg, Norway 1989, Kaldnes Miljøteknologi was established to commercialize and patent MBBR in 1991. Kaldnes Miljøteknologi originated from a company called Kaldnes Mekaniske Verksted, which dates back to 1899. In 1994 Kaldnes MBBR was installed in the Olympic City in Lillehammer, Norway, and in 1995, Anglian Water acquired Kaldnes Miljøteknologi. Kaldnes MBBR is one the best documented biological processes for cleaning municipal wastewater. There is no exaggeration in claiming that the Kaldnes MBBR process probably is the largest environmental success in Norway within the water and sewerage sector. So much so that Kaldnes Miljøteknologi won the “Stockholm Industry Water Award” in 2001, and in 2002, Anglian Water was acquired by Swedish-based company Anox AB. In 2004, Anox AB and Kaldnes Miljøteknologi changed its name to AnoxKaldnes. In 2005, AnoxKaldnes AS acquired JO Water Technology AS and strengthened their position within the market. Resourcing the world with Veolia In 2007, the global French group Veolia acquired AnoxKaldnes and in 2008, the company changed its name to Krüger Kaldnes AS.
