A novel pre-treatment method, the Waste Activated Sludge-High Rate (WASHR) process, is proposed to optimize the co-treatment of high-strength wastewaters. The WASHR process combines the contact stabilization and sequencing batch reactor processes. It utilizes was...
The purpose of this laboratory study was to evaluate, and model the effect of solids retention time in the activated sludge process (θcAS) on the performance of anaerobic digesters fed the resulting waste sludges. Activated sludge systems were operated over a range of θcAS values, with the ...

Conditioning of extra carbon sources has been widely reported to facilitate fermentation of waste activated sludge (WAS). Soy sauce residue (SSR) was a rel
Its advantages include low energy input, methane production and reduction of sludge quantity. However, its application is often limited by low biodegradability and high retention times, because the complexity of WAS limits the efficacy of the biological process (Ruffino et al., 2016). For instance...
Date Sep. 15, 1994The invention concerns a process for increasing the purification yield in the activation tank of a station for the purification of waste waters employing the so-called "activated sludge" process. According to the invention, talc, pyrophyllite, kaolin or mica, possibly cationized...
