Extensive Wastewater Treatment Processes: Adapted to Small and Medium Sized Communities (EC)
European Commisssion
Implementation of Council Directive 91/271 of 21 May 1991 concerning urban waste water treatment
This guide will simply mention intensive techniques and will concentrate, above all, on extensive treatment techniques.
These techniques, by definition, use more land than traditional intensive processes developed for large agglomerations.
However, the investment cost for extensive processes are generally lower, and the operating conditions
of these extensive processes are simpler, more flexible and allow more energy to be saved. Finally, these techniques
require a lower amount of manpower and less-specialised manpower than intensive techniques.
