The leaflet DWA-M 285-2 is intended to serve as a working aid for the planning of activated carbon processes. The information sheet DWA-M 285-2 summarizes previous findings on the dimensioning and design of activated carbon processes for the targeted removal of trace substances and describes the effects of the processes on the operation of the wastewater treatment plant.
Only processes that are already in operation at several wastewater treatment plants or for which there is already sufficient experience from several large-scale studies to be implemented permanently at a wastewater treatment plant are included. Taking into account the design guidelines, it is possible to remove a high percentage of highly to readily adsorbable substances from wastewater at an economically justifiable cost using the activated carbon processes presented.
Against this background, the DWA has started to develop a new series of information sheets DWA-M 285 "Trace substance removal in municipal wastewater treatment plants", which will initially comprise the following parts:
- Part 1: Criteria for process selection with selected examples (in preparation)
- Part 2: Use of activated carbon - process principles and dimensioning
- Part 3: Ozonation - process principles and dimensioning (in preparation).
