Dewaterability of thermophilic digestate: Characteristics and underlying processes: A heuristic comparison of mesophilic digestion, thermophilic digestion and digestate ammonia stripping on the site of Bath WWTP, Netherlands

In a WWTP operating with full scale mesophilic digestion, a thermophilic digestion pilot and a digestate ammonia stripping pilot were installed. Benefits of the aforementioned sludge treatment processes, such as energy and nutrient recovery, are extensively recognized. However, drawbacks, such as deficient sludge dewatering, are amply...
