Zinc, copper and manganese availability in soils treated with alkaline sewage sludge from Paraná state (Brazil)

Ciência e Agrotecnologia
In Paraná, most of the sludge generated in sewage treatment plants is subjected to the prolonged alkaline stabilization process. Although it is known that the alkaline sewage sludge contains micronutrients such as Zn, Cu and Mn, little is known about the

Mesophilic anaerobic co-digestion of sewage sludge with glycerine: Effect of solids retention time [PDF]

, 2018
The main objective of this paper is to examine the effect of the increase in organic loading rates (OLRs), by reducing the solids retention time (SRT) from 20 d to 5 d, in single-phase mesophilic anaerobic co-digestion of sewage sludge with glycerine ...

Studies on the Stability and Microbial Biotransformation of Five Deschloroketamine Derivatives as Prerequisite for Wastewater‐Based Epidemiology Screening

Drug Testing and Analysis, EarlyView.
Microbial biotransformation and stability of deschloroketamine derivatives and their metabolites in WW by incubating parent compounds, rat urine, or rat feces showed that deschloroketamine parents and Phase I metabolite were still detectable and that Phase II metabolites decreased in peak areas.
