Tehnologija potopnega membranskega bioreaktorja (MBR)

Ta evropski standard določa sistem za klasifikacijo tehnik brez izkopa za obnovo, popravilo in zamenjavo na istih vodih in kanalih zunaj stavb, ki delujejo s pomočjo gravitacije ali tlaka, vključno s cevmi, priključki in jaški. Določa in opisuje družine tehnik in njihove različne splošne metode ter uporabljene materiale.
Ta evropski standard se ne uporablja za zamenjavo s tehniko odprtih jarkov v skladu s standardom EN 1610 ter za izvedbo in preskušanje vodov in kanalov brez izkopa v obliki nove izvedbe izven obstoječega voda ali kanala v skladu s standardom EN 12889.
Ta evropski standard se ne uporablja za specifikacijo zahtev glede specifičnih izdelkov.
Za vsako družino tehnik navaja ustrezne obstoječe standarde, materiale in uporabe ter opisuje tehnične značilnosti, vključno z vidiki namestitve, strukturnimi in hidravličnimi sposobnostmi ter vplivom na mesto cevovoda.
Ta standard se ne uporablja za nobeno delo, ki je potrebno na obstoječi cevi pred prenovo, popravilom ali zamenjavo.
Ta evropski standard vsebuje informacije, ki so potrebne za določitev optimalne tehnike v povezavi z danim naborom ciljev glede prenove, popravila ali zamenjave.
OPOMBA:   Načrtovalec je odgovoren za izbiro in načrtovanje sistema za obnovo in popravilo.
Dokument ne določa računske metode za določanje, za vsako izvedljivo tehniko, potrebne količine materiala, ki je potreben za zagotovitev želene učinkovitosti cevovoda, ki bo obnovljen.

This document is based on the CWA 15897:2008, Submerged Membrane Bioreactor (MBR) Technology
which was prepared by the CEN Workshop 34 – 'Submerged' Membrane Bioreactor (MBR) technology.
This document supersedes CWA 15897:2008.
Introduction
This document deals with custom designed MBR systems for more than 500 PT. It became clear that it is
not possible to have interchangeable membrane modules without considering a complete system. So
this led to the conclusion that this document deals with the entire membrane system rather than the
membrane modules alone.
It was realized that today’s market is a growing one with fast developments in membrane technology.
Standards might be too early and may hamper the technological development. So it was decided at this
stage to create a basic document for submerged MBR technology by means of a Technical Report.
Regarding interchangeability of MBR systems, this document especially focuses
