Are there any (national) technical guidelines for the process design of a full-scale water resource recovery facility applying the aerobic granular sludge process?
The guideline should emphasize on the biological wastewater treatment.
Granular sludge are dense layers of microorganisms that have a syntrophic metabolism, in which none of the species present can degrade complex organic waste individually. Activated sludge is a mixture of wastewater with microorganisms in which, through aeration, oxygen is absorbed, contaminants are eliminated and the liquid obtained is redirected to a sedimentation tank. There are three main stages of treatment, in which we find different associated processes, these are: 1- Thickening. 2- Stabilization. 3- Dehydration.
