What type of WWTP is this? Generally i have found that M Parvicella manifests itself in systems with very long MCRT's and low F/M ratios. I have also seen that while you may think DO in your biological treatment tanks is the issue, the "septic conditions" that can sometimes cause it are actually found in the upstream collection and treatment steps (ie organic acids being developed in a septic tank or septic layer of a tanks). Look at trying to reduce your MCRT and F/M ratios first and investigate your upstream equipment and holding tanks
