LagoonGuard™ for industrial and municipal wastewater treatment

Enhancement and upgrading of aerated lagoons

Aerated lagoons are used extensively in many areas for treatment of both municipal and industrial wastewater. In North America there are thousands of larger lagoons treating municipal wastewater. These systems can adequately remove COD and BOD but nitrification is not readily accomplished giving poor nitrogen removal .

As municipalities with aerated lagoons are increasingly required to limit the release of ammonium to receiving waters they are facing the hard choice of whether to build an expensive completely new process or to somehow upgrade the lagoon in order to obtain nitrification.  At AnoxKaldnes we believe that lagoons are excellent technologies, so why not let them continue to do what they do very economically and efficiently, but with a little help.  Thus our solution is the LagoonGuard™ lagoon upgrade.

The LagoonGuard™ entails a well designed supplementary MBBR™ biofilm process after the lagoon which will handle the ammonium and may even provide some additional COD removal. The upgrade is easy and economical, compact and, in the spirit of the lagoon itself, the LagoonGuard™ upgrade requires a minimum level of maintenance.

The LagoonGuard™ is a result of our research in the area of MBBR™ biofilm technologies for advanced wastewater treatment process.
