Jet aerators use small nozzles to release a jet of fluid to aerate liquids and slurries in process tanks. They rely on chopper pumps to macerate solids and prevent clogging. They are used in wastewater treatment, food and chemical processing, and can be customized for specific applications.
Jet aerators are devices that aerate liquids and slurries using small nozzles that release a jet of fluid to aid circulation in the process tank. The fluid creates turbidity and bubbles, which circulate through the mixture to aerate it evenly and reliably. Jet aeration devices can have any number of jets, with the number usually determined by the size of the tank. A single nozzle may suffice for a relatively small vessel, while others may have arrays of 30 or more on a rotating arm to evenly aerate everything in the process vessel.
These devices commonly rely on a chopper pump to drive the fluid through the jet. Chopper pumps macerate any solids in the fluids they process, allowing them to flow smoothly through the jets. This is important for jet aerators in sludge and mixed material tanks. Without steeping, the jets could over time become clogged with mix components, forcing the operator to stop and empty the process tank to access the jets for cleaning.
A variety of applications are suitable for jet aerators. One of the most common is wastewater treatment, whether in a home septic tank or a wastewater treatment plant. Aeration is essential to promote the growth of beneficial bacteria to break down wastewater quickly and speed up the treatment process. While anaerobic organisms can eventually process these materials, they take much longer and can produce a range of strong odors. It is also possible for pathogens to thrive in the mixture, which is undesirable.
Businesses can also use jet aerators to process various food and chemical products and in the treatment of a variety of blends. The jets can come in various sizes and can have adjustable angles to handle different environments. Whether stationary or mounted on a rotating arm, they provide an even and adequate coverage to aerate an entire mix. In the event that the jet aerators become clogged, as can happen periodically even with a macerator pump, the operator can empty and flush the tank to remove lumps of material.
Manufacturers of aerators and jetted components can produce customized versions for specific applications. They are usually made from minimally reactive materials, as they can be used in processes involving corrosive or aggressive chemicals. If there are specific concerns regarding how the aerators will be used, the manufacturer can develop an appropriate custom product that should be safe and reliable.
