High TDS in Treated water from MBR process

Published on by in Technology

Dear  all,

I found High TDS in treated water from Membrane bioreactor (MBR) process.

Analysis of TDS before MBR showed it was very low, 

For chemical injection consist of NaOH and HCl for pH adjusting in nitrification tank.

Pls  recommend  how to solve it?

Thank you
