Not all aeration is about oxygen — sometimes the job is to keep solids suspended and the basin homogeneous. Low-speed submersible and hyperboloid mixers move large volumes gently, with or without coupled aeration, for anoxic and equalisation duties.
What this aeration technology is, where it fits, and the numbers that define it.
The faults that undermine this technology in the field, and the engineering response to each.
What you see: Solids accumulate on the floor despite a mixer being installed.
What you see: Mixer current rises and thrust drops as rag wraps the propeller.
What you see: Surface disturbance adds oxygen where denitrification needs none.
Right-sized mixing protects the biology — keeping solids in suspension for the bugs to work on, without adding oxygen where the process needs an anoxic environment.
Membrane disc/tube diffusers for high-efficiency oxygen transfer.
Mechanical surface and aspirating aerators for robust, retrofit duty.
Pumped jet and venturi systems for deep tanks and high mixing.
Blower selection and DO-based air control for energy efficiency.
SOTE, alpha factor and how to specify and verify aeration performance.
Our engineers size aeration on real oxygen demand, select the right technology for your tank and load, and verify performance by test — from diffusers to blowers and controls.
