Ammonium rich wastewater treatment and value addition using microalgae bacterial consortia in photo activated systems

Abstract

The conventional activated sludge process ASP for ammonium removal relies on mechanical aeration In addition to very high operating cost due to mechanical aeration ASP requires addition of external carbon source for nitrification and denitrification On the other hand microalgae bacteria consortia are not only able to grow autotrophically on ammonium but also offer advantages such as high N affinity anoxic zone for denitrification algal photosynthesis shortcut nitrogen removal biomass...
