www.fpharm.uniba.skActivated carbon, also called activated charcoal or activated coal, is a general term that includes carbon material mostly derived from charcoal. For all three variations of the name, "activated" is sometimes substituted by "active." By any name, it is a material with an excep- tionally high surface area.
Biological Wastewater Treatment Processes I: Activated Sludge
www.cedengineering.comThe Conventional Activated Sludge Process is used over a wide range of wastewater flow rates, from small to very large plants. The flow diagram and general description is that given above in the Activated Sludge Background section. The aeration tank in a conventional activated sludge process is typically designed with a long, narrow
