AnoxKaldnes is a renowned brand that specializes in designing innovative biological wastewater treatment solutions. With our state-of-the-art MBBR (Moving Bed Biofilm Reactor) technology, we effectively remove pollutants from wastewater in a cost-efficient manner. Our expertise in biological treatment of wastewater has made us world leaders in the industry, with our solutions implemented in over 1,200 treatment plants worldwide.

The foundation of AnoxKaldnes traces back to the mid-1980s when Thomas Welander, a doctoral student at Lund University, developed a groundbreaking approach to wastewater treatment. By understanding and harnessing the power of nature's microorganisms and biofilm formation, Welander created controlled environments for microorganisms to optimize treatment processes. Partnering with Professor Hallvard Ødegaard's invention of the MBBR technology, AnoxKaldnes became a leading force in biological water purification.

In 2002, AnoxKaldnes acquired Kaldnes and merged their expertise, solidifying their position as industry pioneers. Today, AnoxKaldnes continues to lead the way through research and development, constantly innovating and developing new technologies. Our focus extends beyond wastewater treatment, as we strive to minimize energy consumption and promote the circular economy.
