The topic:   Troubleshooting, municipal wastewater treatment by MBRs

The client:  Gulf-based properties and facilities development company

The brief

This job involved assessment of the design and O&M data of a large (>50,000 m³/d capacity) MBR plant in the UAE for which the CIP was failing to recover the permeability. Clogging was evident at this site, and an examination of permeability trends at other MBRs in the region revealed that they were subject to the same problem. Through benchmarking against other sites subject to the same general climactic conditions, it was demonstrated to the client that the design fluxes were overly ambitious and that additional membrane area was needed.
