MBR Colour

In my experience MBR's generate colour, particularly in a reuse application with recycling.  If you are meeting a reuse water quality then you have to disinfect.  The colour will likely interfere with UV, but chlorination can be carried out to both disinfect and will take care of the colour.  With respect to your cost concern, chlorination is likely your least expensive option and the dosage required to meet your CT requirement will address the colour problem.
