sludge MLSS does not reach 7,000 mg/L, and gradually increase the flux
considering F/M ratio. Initial seeding sludge is not yet acclimataized to the MBR
operation and in such condition filtration with higher flux may lead to membrane
fouling.
(2)
Sludge parameters such as MLSS and sludge filterability should be checked
frequently to assess the actual sludge condition.
(3)
Check the air diffuser cleaning procedure and confirm it works. Details for the
procedure are given in the chapter VIII
(4)
Once the permeate water flow is stabilized, please measure and record the
trans-membrane pressure and the liquid temperature. The details for operation
control are given in the next chapter.
