Municipal Wastewater

Just adding some plastic, moulded into a peculiar shape, to a wastewater basin and seeing what happens is a quick way to failure. Besides the specially designed carriers, you need knowledge of microbiology, hydraulics and engineering to design a long-term solution.

There is continuous, ongoing, research and development of AnoxKaldnes™ MBBR technology. Existing processes are improved and processes for new applications are continuously invented.

A broad range of different carrier types has been developed in order to target the specific needs of different projects. The over 700 installations spread all over the world show many have discovered the benefits with a biofilm process based on AnoxKaldnes™ MBBR technology.

Some of the major applications in wastewater:

  • BOD reduction
  • Nitrogen reduction

Drinking water

The AnoxKaldnes™ MBBR technology is an ideal solution for treatment of potable water whenever there is a need for removal of biologically transformable pollutants, such as NH4+, NO3- or organic compounds.
