Treatment of Dewatering Sidestream from a Thermal Hydrolysis-Mesophilic Anaerobic Digestion Process with a Single-Sludge Deammonification Process

Comprehensive Source Control for Potable Reuse

“…Because many dewatering operations are conducted as batch processes it may also be necessary to flow equalize the return sidestream before treatment. Sidestream treatment of one form or another has been conducted at the Washington D.C. Blue Plains Advanced Wastewater Treatment Plant since 2011 (Figdore et al, 2010(Figdore et al, , 2011. Where satellite treatment plants are used, as discussed in the following section, all return flow sidestreams are discharged to the collection system for treatment at a downstream regional WWTF.…”

Lessons Learned from 10 Years of ANITA Mox for Sidestream Treatment

“…THP pre-treatment also allows reducing considerably the size of the downstream digester due to the lower viscosity of hydrolysed sludge. The downside of all these benefits, return sidestream from a THP + AD sludge treatment, can generate up to 30% additional N-load to the WWTP and produce intermediate inhibitory compounds [3,4]. Therefore, a sidestream treatment process installed today for the dedicated treatment of conventional anaerobic digester reject water should consider the possibility that THP may be installed in the future, leading to higher N-load to be treated and a specific process operation strategy to overcome the toxicity of THP.…”
