A research team from the Gas Processing Center (GPC) at Qatar University College of Engineering (QU-CENG) with external collaborators from Public Works Authority - Qatar (Ashghal) and Qatargas have developed a method for testing clogging of membrane bioreactors (MBRs).
The team includes GPC Environmental Engineering Chair Prof Simon Judd, GPC Post-doctorate Researcher Dr Pompilia Buzatu and CENG Department of Chemical Engineering Co-Principal Investigator Prof Hazim Qiblawey.
Themed “Membrane bioreactor technology: a new approach for improved process robustness”, the work has been conducted as part of the National Priorities Research Program (NPRP) project.
The team studied municipal and industrial wastewater sludge samples from plants at Lusail and Ras Laffan. They used a bespoke test cell designed to allow direct viewing of the membrane channel for clogged solids. Sludge from existing operating MBRs has been introduced into the cell and their clogging behaviour has been observed directly. The image of the clogged membrane channel was then translated to a number indicating the extent of the clogging.
The study revealed that both ways in which the membrane clogs the channels.
