Remarks:

  • These is basic instrumentation to operate the activated sludge system or membrane bioreactor. The more instrumentation analysis are required for more detail observation.
  • The other parametersthat could be required to be tested are, NO-2 -N, NO-3 –N, total phospor (TP) and total nitrogen (TN).
  • The detail can be found and standard method for wastewates analysis.

The operating parameters is determined according to the pilot plant parameters from MBR companies.
