What is PD CEN/TR 15897- MBR technology about?
PD CEN/TR 15897 discusses submerged Membrane Bioreactor (MBR) technology. PD CEN/TR 15897 defines terms commonly used in the field of membrane bioreactor technology. PD CEN/TR 15897 aims at submerged MBR systems for the treatment of municipal wastewater with MBR Separate Systems and MBR Integrated Systems.
PD CEN/TR 15897 establishes general principles for MBR filtration systems interchangeability between different MBR filtration systems from different manufacturers. Carbon removal is required, and complete nitrification is recommended in MBR systems. Short circuits, high concentrations of extracellular polymeric substances (EPS), or incomplete biodegradation of wastewater may affect filterability.
Who is PD CEN/TR 15897 - MBR technology for?
PD CEN/TR 15897 on MBR technology is useful for:
- Flat sheet membrane manufacturer
- Flat sheet membrane design
- Municipal bodies
- Wastewater treatment plant
- Scientists
- Biology laboratories
Why should you use PD CEN/TR 15897 - MBR technology?
Regarding the interchangeability of MBR systems, PD CEN/TR 15897 especially focuses on separate membrane tanks as there is a tendency that large MBR systems (more than 10 000 m3/d) are designed with separated membrane tanks.
PD CEN/TR 15897 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. This led to the conclusion that PD CEN/TR 15897 deals with the entire membrane system rather than the membrane modules alone.
Although there are differences between hollow fibre and flat sheet membrane manufacturers’ designs, it is believed that there is no need for separate guidelines because these are focused on membrane tanks.
