6.0 PLANT START-UP, OPERATING GUIDELINES AND MONITORING

6.1 MBR Plant Start-Up

6.1.1 Mechanical & Electrical Start-up Procedure
If the system is being started for the first time, work your way through the newterra
Commissioning Checklist presented in Appendix C of this O&M Manual.
If the kill switch on the panel (red mushroom shaped button) is pulled out, then push it in
to confirm that the MBR system is off.
Push the reset button on the operator interface to reset all alarms.
Make sure there are no obstructions over any moving parts, for example a jacket laying
on a belt drive.
Put all HAND/OFF/AUTO switches to AUTO (A) mode.
Pull the kill Button (red button on panel) out to start the process.
Push the start button on the Operator Interface.

6.1.2 Process Start-up

NOTE: Sludge from a nearby wastewater treatment plant can be used to start up another
system if the treatment process is similar (i.e. nitrification, de-nitrification etc.).
1. Introduce the seed bacteria and fill the aeration tank according to one of the following
two methods specific to the type of seed used:
Sludge Seed
a. Calculate the volume of seed sludge required to ensure that there is a minimum of
3,000 mg/L MLSS in the MBR system. The volume of seed sludge required can be
calculated with the following formula.
Vs: Total volume of seed sludge for MBR system (m3)
Vt: Total effective volume of process tanks in MBR system (see section 3 of the
manual) (m3)
MLSSs: MLSS concentration of seed sludge from a treatment system with similar
processes (nitrification, de-nitrification etc.) (mg/L)
