To a layman, effluent treatment plant can just inspire a grimace but if we delve further from an engineer’s point of view, it can also inspire awe. Effluent treatment plants have high tech machineries; they are controlled by local government bodies and laws and they can not only create a cleaner today but also a greener tomorrow. Let us understand all this in detail below.

What is aerobic treatment process?

Aerobic treatment process is one of the vital parts of effluent treatment plan. It looks like it is just a small part of the effluent treatment system, but in fact aerobic treatment process is one of the integral and unavoidable parts of the process. Through proper aerobic treatment, plants and sewages can save more energy, cut down costs and also preserve precious oxygen with installations of aerator system.

How does it work?

The mechanism behind aerobic treatment process is very simple. It helps in mixing oxygen with the sludge and waste with high velocity rotators. However, the naturally available oxygen is not enough for the waste as they have high demand of oxygen. To solve this problem, ...
... aerobic tanks that provide oxygen boost up are put up. Aerators help blend the sewage in an extremely vigorous method with the oxygen. This is done by thrusting the oxygen so that it is evenly distributed throughout the area.

What are the types of aerators?

There are two types of aerators – ones that can be mounted on a fixed support and ones that can be mounted on floating support. The fixed aerators or the aerators mounted on fixed support are more commonly found in effluent treatment plants as they conserve more energy and are more conventional.

The floating types of aerators are relatively newer and mounted on a pod-like surface that floats in the plants. These are found in plants that run very deep. The best part is they are easy to install and more cost-friendly as we need not build a platform for them.

Which types of aerators are considered good?

There are three basic characteristics of good aerators – they are 1) oxygen effectiveness, 2) vibration levels and 3) use of latest technological inventions. Good aerators will have high output of oxygen effectiveness. They will have heavy base frame made from quality materials to reduce vibrations and lastly they will use the latest technical features like semi-open impellers. Besides these, good aerators will also yield high return on investments by cutting down on energy use.

Other than that, the base of the aerator is very important. The small to medium aerators from 5HP to 20HP can have fabricated base frame but the large aerators must have a heavy beam base. This is of utmost importance as it is required to reduce vibrations. The newest feature that is considered a value addition is having semi-open impellers that can clean themselves.

How can aerators help in creating a greener tomorrow?

Without effective and resource-optimal effluent treatment plants, it would be impossible to cast off the voluminous amount of waste created domestically and commercially. Aeration, though just a small part of effluent treatment process, plays an important role in preserving the nature. Good aerators provide high levels of oxygen transfer efficiency and energy efficiency and hence preserve valuable atmospheric oxygen as well as energy. This directly translates into a greener tomorrow. In conclusion, we can safely say energy efficient aerators can help us save more energy, so that we can have a cleaner, greener and a better tomorrow.
