Photo Nathalie Hubaux, CEO of the Neugut wastewater treatment plant at Dübendorf, and Marc Böhler, a<br />
group leader in the Process Engineering department, inspect and discuss the operation of the long-established<br />
sand filtration process at the plant. As well as serving the existing function of removing solids from biologically<br />
treated wastewater (thus increasing the retention of nutrients), the filtration process is now also being used for<br />
biological post-treatment of wastewater that has undergone ozonation, serving to eliminate unstable transformation<br />
products arising from this recently introduced process.
