TL;DR: Life Cycle Assessment is used to evaluate different disinfection treatments and to assess the environmental advantages and drawbacks of urban wastewater reuse in non-potable applications and to compare the environmental impacts of producing 1m(3) of water from reclaimed water, potable water and desalinated water sources.

TL;DR: Acidic pharmaceuticals, caffeine, and the antibacterial triclosan were quantified at four different steps of wastewater treatment from three urban wastewater treatment plants, yielding expected surface water concentrations of 13 to 56 ng/L.
Abstract: Pharmaceuticals are a class of emerging contaminants whose fate in the wastewater treatment process has received increasing attention in past years. Acidic pharmaceuticals (ibuprofen, naproxen, mefenamic acid, ketoprofen, and diclofenac), caffeine, and the antibacterial triclosan were quantified at four different steps of wastewater treatment from three urban wastewater treatment plants. The compounds were extracted from wastewater samples on Waters Oasis hydrophilic-lipophilic balance solid-phase extraction columns, silylated, and analyzed by gas chromatography-mass spectrometry. For the chemicals studied, it was found that the majority of the influent load was removed during secondary treatment (51-99%), yielding expected surface water concentrations of 13 to 56 ng/L.

TL;DR: Removal of waste, natural leaching and biological activity, in time, led to an effective decrease in electrical conductivity and phenolic compounds, although residual levels can be important even 2 years later.

TL;DR: In this article, photo-Fenton oxidation was used for post-treatment after an anaerobic biofilm process, in a way to minimize the reagents needed to reduce the toxicity of textile effluents.

TL;DR: Across the treatment systems examined, the majority of pharmaceuticals observed in on-site and municipal effluent discharges were predicted to potentially present therapeutic hazards to fish, and removal by these wastewater treatment systems was generally not influenced by season.
