Abstract EN
Komurcuoda leachate treatment plant, Istanbul, which consists of membrane bioreactor (MBR) and nanofiltration (NF) system, faced rapid flux decline in membranes after 3-year successful operation.
To compensate rapid flux decline in membranes, the fouled membranes were renewed but replacement of the membranes did not solve the problem.
To find the reasons and make a comprehensive analysis, membrane autopsy was performed.
Visual and physical inspection of the modules and some instrumental analysis were conducted for membrane autopsy.
Membranes were found severely fouled with organic and inorganic foulants.
Main foulant was iron which was deposited on surface.
The main reason was found to be the changing of aerator type of MBR.
When surface aerators were exchanged with bottom diffusers which led to increasing of dissolved oxygen (DO) level of the basin, iron particles were oxidized and they converted into particulate insoluble form.
It was thought that probably this insoluble form of the iron particles was the main cause of decreased membrane performance.
After the diagnosis, a new pretreatment alternative including a new iron antiscalant was suggested and system performance has been recovered.
