The Mechanical Equipment Used in Water Aeration
The same way man needs hands to eat and work, you also need to have mechanical equipment to perform water aeration. Without it, cleaning contaminated water through this method cannot be performed efficiently.
The Old Method
Even before the invention of modern-day aeration technology, we still rely on equipment to clean bodies of water—not very high-tech, but it is still equipment. One such apparatus is called the aeromix.
The aeromix has first been used in 1929. How does this equipment work? Water flows into the tank around the head of the aeromix. The water passes through several areas before the water can be effectively aerated.
After entering the head through the apertures, the water passes down into the annular throat down multiple tubes. While passing through these, bubbles of air are drawn through these tubes by aspiration.
At this point, both water and air go through the retention pipe and when it reaches the discharge plate, the air is released and the water is left cleansed.
Present-Day Aeration Equipment
Today, there is more than just one mechanical apparatus used in aerating water. These can be classified into two basic types: waterfall and diffusion.
The waterfall type is designed in such a way that multiple riser pipes are subdivided into thinner sheets so better aeration of the water can be achieved. Steps arranged vertically, shelves and auxiliary pans are added to increase spattering of water, giving it enough time to have contact with the air and be oxygenated.
Instead of riser pipes, some waterfall type designs utilize distributing flumes which discharges the water into an inclined plane studded with iron plates, a basin or weir troughs.
In the diffusion type of aerator, diffuser plates placed at the bottom of aeration tanks are used to clean the water. These plates or diffusion units are the source of air bubbles and controls how fast they are going to move, which in turn controls how efficient water aeration is going to be.
Several other designs introduced air into the water with the use of blowers, the air passing through diffusion tubes that are hanging in a spiral flow tank. Typically, allowing the water to get in contact with the air for at least fifteen minutes is enough to aerate it.
