TL;DR: In this paper, a series of discs mounted on a common shaft are used to extract impurities from a wastewater treatment process, and activated carbon is added at each disc to improve the operating characteristics of the biological contactor.
Abstract: The invention relates to a wastewater treatment process. In one embodiment, introducing raw sewage in a biological contactor 22 having a series of discs 24 mounted on a common shaft 25. To the wastewater stream an adsorbent capable of adsorbing impurities from the liquid. This adsorbent is, for example activated carbon is added at 26. The addition of this adsorbent improves the operating characteristics of the biological contactor and the solids were removed accumulated on the contactor at a rate equivalent to the rate at which these solids accumulate.

TL;DR: This review argues that the information available is insufficient for precise process design and optimization, and simultaneous activated sludge treatment of wastewater and airborne odours could be adopted worldwide.
