TL;DR: The toxicity of ibuprofen and its intermediate compounds formed during the oxidative process was studied and was found to increase with increasing initial concentrations of the compound, with the intermediate compounds thus formed being more toxic than the starting compound.

TL;DR: In this paper, the authors studied the influent and effluent of two wastewater treatment plants, both located in Cadiz, with different wastewater source (industrial and urban), as well as the receiving water bodies where the facilities discharge their sewage.

TL;DR: The results indicate an extensive biodegradability of AES in sea water, although at a very slow rate, and highly dependent on the species tested, being the green alga D. salina the most affected organism.

TL;DR: Only TCS seems to be very effective in reducing sludge production from the activated sludge process, and an increase in the microbial activity of the system was observed, and the substrate removal capability was not adversely affected by the presence of TCS.

TL;DR: The oxic-settling-anaerobic process is applied in combination with ultrasound treatment, a lysis technique, in a lab-scale wastewater treatment plant to assess whether sludge reduction is enhanced as a result of mechanical treatment.
