Planung, Bau und Erprobung einer Demonstrationsanlage zur Verbesserung der Grundwasserqualitaet durch gesteuerte Denitrifikation im Aktivkohlefilter mit aerober Nachbehandlung im Untergrund Abschlussbericht

A biological process for the sanitation of nitrate polluted groundwater has been developed and tested. In this process denitrification is carried out in fixed bed reactors filled with granular activated carbon and with acetic acid as a nutrient for the denitrification bacteria. Using the porous, groundwater conducting subsoils for an underground aerobic post-treatment, the water treatment plant possesses a high degree of operational safety. Water sterilization or desinfection is therefore in the water works under study (Broichhof/Neuss) not necessary.
