TL;DR: A review of the state-of-the-art of acid mine drainage can be found in this article, where the authors critically analyze the work performed in recent years on its occurrence, effects (on human health, plant life and aquatic species), and summarizes the remediation approaches taken so far to overcome the problem of AMD.

TL;DR: In this paper, the authors provide a review assessment of the current status of the brewery wastewater treatment processes including potential applications for reuse, and provide recommendations for future developments, as well as discuss key challenges for both the treatment and reuse of brewery wastewater.

TL;DR: In this paper, some of the techniques used to recover sulphuric acid from various wastewater solutions are reviewed, including rectification, membrane separation, solvent extraction, crystallization and acid retardation.

TL;DR: Investigation of whether carbon nanotubes can be used as heterogeneous coagulants and/or flocculants in the pretreatment of brewery wastewater found ferric chloride to be a more effective coagULant than both the pristine and functionalised CNTs.

TL;DR: The use of less toxic, less flammable extractants like ionic liquids for recovering the PGMs out of solution presents benefits in terms of increased recoveries and safety of operating conditions.
