TDS is high in the membrane ...
Published by Nasrul Isa
TDS is high in the membrane process, presumably because the membrane is unable to filter the water properly, there are several causes:
1. The membrane filter is already full of flak and dirt from microorganisms and their carcasses, and the membrane may be stiff and hard.
2. The membrane filter is not smooth enough and the pores are too big to filter.
3. There is indeed a weakness of membrane filters, it cannot completely filter out all pollutants in water, especially heavy metals such as pesticides and others, as well as carcasses from microorganisms in the form of enzymes.
There are many other factors that cause the membrane filter to not work, so it needs to be pre-treated before the water is filtered. Sorry, on this occasion I offer pre-treatment formulas and alternative systems to get clean water from sources: ground water, surface water (rivers, swamps, lakes) and from wastewater. See me at Linke dIn. Thank you.

MBR isn't a driven pressure process like as RO. It's a UF membrane that can't reject dissolved salts (TDS). Normally with size pore in range 0,1-0,04 micron. When you are passing activated sludge trough MBR you can't expect a change in TDS.
