The Town needed to address both long and short term wastewater treatment ...

  • Biofiltration WWTP 50.000 PE

    The aerated upflow biological filtration (biofiltration) is a technology which is today successfully used in more than 500 European wastewater treatment plants. Among this, the one of Sallek Valley, in Slovenia, differs by a two stage biofiltration and a part-recirculation of sludge from thickener to increase the COD concentration needed for denitrification. This process allows an advanced ...
