Aerators

The activated sludge method of purifying sewage can be divided into two basic elements: (a) The efficient supply of ample oxygen to support the bacteriological processes. (b) Sufficient circulation of the tank contents to achieve intimate mixing of the activated sludge and sewage and to avoid practical disadvantages such as the deposition of sludge and slit.

Fundamental Principals Of Aeration :

The activated sludge method of purifying sewage can be divided into two basic elements:

(a) The efficient supply of ample oxygen to support the bacteriological processes.

(b) Sufficient circulation of the tank contents to achieve intimate mixing of the activated sludge and sewage and to avoid practical disadvantages such as the deposition of sludge and slit.

The action of the Aerating Cone combines these two basic functions with maximum efficiency. It was also recognised that mixing could be achieved most economically by mechanical means and the Aeration Cone is a highly efficient, which, in combination with the stationary uptake tube, and efficient mixing of the contents of the tank

The special designed blades of the Cone discharges the circulated liquid in a manner which achieves high uptake of oxygen as the liquid passes through the atmosphere and strikes the surface with great force. A very rapid solution of oxygen is thereby promoted, which is immediately utilised throughout the contents of the aeration tank because of the rapid circulation.

Salient Features Of Aerators :

High intensity Aeration process in the most efficient, economical and trouble free of purifying sewage by activated sludge process.

Outstanding advantages of process are:

• Lowest Capital Cost.

• Lowest Power Consumption.

• Lowest Maintenance Cost.

• Flexibility of Plant Design.

• Flexibility of Plant Operation.

• Continues Trouble Free Services.

• Simplicity of Mechanical Equipment.

The continuing development and success of high intensity Aeration process is possible because correctness of fundamental principles and development of Cone.
