Dear Mathieu,
What kind of sludge are we talking of ? Primary, secondary (stabilised/unstabilised), digested, dewatered, thickened ?
In the end it depends what you are doing with the sludge afterwards. If you do anaerobic digestion, you will lose some biogas since your sludge gets (slightly) digested aerobically.
Otherwise they are not many drawbacks, except that your diffusers might clog with a crust if you do not aerate enough. People like that solution since there is no rotary equipment inside the tank, and in your case a mixer doesn't seem to make much sense because of water level depth.
Best regards,
Patrick

Hi All,
Tank is a retention/collection tank that received septic tank sludge before dewatering (the main goal of the facility, which is also equipped with sludge press).
From that tank, sludge is pumped toward the press for dewatering.
