Kinetic and mechanistic investigations of the degradation of propranolol in heat activated persulfate process.

This study investigated the heat activated persulfate (heat/PS) process in the degradation of propranolol from water. Various factors (, temperature, persulfate dose, initial pH and natural water constituent) on PRO degradation kinetics have been investigated. The results showed that the PRO degradation followed a pseudo-first-order kinetics pattern.

Two-phase anaerobic co-digestion of food waste and sewage sludge.

The feasibility and performance of food waste and sewage sludge co-digestion were investigated to gain insight into their resource utilization. In this study, two-phase anaerobic digestion (TPAD) was operated under a total solids mixing ratio of 1:1 and different sludge retention times (SRTs). Results show that an acidogenic reactor with a 5-day SRT obtained the highest acidification efficiency, and its acetic acid content was dominant.
