Abstract
Granular sludge technology – NEREDA is one of the most significant achievements in environmental biotechnology of the XXIst
century. NEREDA is the latest innovative technology for biological wastewater treatment, which purifies water using the unique
characteristics of aerobic granular biomass. Unlike conventional processes, bacteria of the biological process naturally focus in
compact granules with good settling properties.
Due to the variety of biological processes that occur simultaneously inside the granular biomass (nitrification, denitrification),
NEREDA is able to produce a high quality effluent with low power consumption. The study investigates the performance of Epe
wastewater treatment plant, the Netherlands, before and after the implementation of NEREDA technology. Good research results
developed by Dutch specialists are confirmed by this Case study and certify that this technology is a reliable and sustainable one
in terms of economic and environmental performance.
