oxygenation with high running costs is the norm - expensive installations requiring high-energy input frequently deliver mediocre performance - and in wastewater applications it is difficult to measure efficacy. Although quantifiable
standards are hard to find common logic provides convincing evidence. Check out aeration & oxygenation and consider the review of various approaches below - it could save you thousands!
There are many products and systems designed to aerate  wastewater. These range from high-maintenance diffused air/oxygen systems using membranes and complex manifolds layouts to simple floating splashers and rotors. While these systems introduce a certain amount of oxygen into wastewater there is a wide array of effectiveness and efficiency among these methods.  The process of oxygenation  is a challenging event!  Incomplete
SURFACE AERATORS (1) show minimum effective reach. Air spraying accelerates heat loss as well as allowing odors to escape.


DIFFUSED AIR (2) system shows effect of air moving straight up too quickly to allow mixing. Most of the area remains untreated


WMS AERATORS (3) show complete coverage of the lagoon area. Heat loss is lessened, making WMS AERATORS more effective in cold weather
1. SURFACE AERATORS: This system pumps water upward, high into the air. Not only does it require a lot of energy to overcome the force of gravity, but the high plume creates an odor-releasing aerosol environment. Because of the lack of horizontal movement, solids quickly accumulate in the dead areas of the basin between the aeration units.
2.  DIFFUSER SYSTEMS: Compressed air passes through diffusers in the bottom of the pond. High horsepower is needed to overcome the water head resistance. The oxygen rises vertically and escapes quickly before effective horizontal dispersion can take place.
3. ROTOR SYSTEMS: These are expensive to maintain, use a lot of energy and need frequent maintenance. They also create aerosol environments releasing odors and are inefficient in suspending solids uniformly.
This aerial photograph shows three water treatment ponds, each with a different aeration system installed. the snow cover on each pond serves to clearly define the circulation activity generated within each pond by the different aeration methods.
CIRCULATION FOR OXYGENATION
The unique design concept of the WMS generates complete 360° circulation to any depth. As soon as water passes through the WMS it is 100% oxygenated

HOW MUCH ?
Compared to other aeration systems, the compactness of the WMS oxygenator belies it's efficiency.
The ability to treat large volumes of water reliably and at low running costs make the WMS the class leader.
