European standardization for urban wastewater treatment

Abstract

The preparation of European Standards concerning the wastewater engineering field is nearly finished and should end up at a rather complete series of standards. This paper proposes an analytical description of these European Standards (EN) and projects (pr EN) achieved or under processing in the field of urban wastewater treatment. The authors, directly involed in these standardization works give testimony in this european experiment. They explain how some progresses have been developped towards, by example, some forms of codes of practise only listing points to be considered during the design phase of projects or in other cases performance specifications with the relative methods for compliance testing, or rather numerous design specifications concerning safety in the wastewater treatment works, trilinguial vocabulary about wastewater, or at least the aeration tranfer efficiency measurement.
