The municipality of Norrtälje came together with the operator Veolia Water to VA Teknik when they refurbished the Trickling Filter and changed the media from the old fashioned rock solution to modern plastic media at Hallstavik WWTP.
VA Teknik supported the consultant during the entire feasability study and final design of the refurbishment of Hallstavik WWTP trickling filter, Sales Manager Marko Kunerus explains “We provide a wide range of solutions with all necessary applications for all kind of trickling filters, in this particular case we had a quite varying flow to consider and some challenges with the structural design which we needed to address. The project fell out great and the performance is actually better than both we and our client expected”
