The Chaipattana Aerator is capable of adapting to fluctuations in the water levels. The main components include:
1) Twelve arm buckets frame with a diameter of two meters.
2) Six of the 110 liters of water spraying buckets are perforated and attached to the rim of the frame.
- The water spraying buckets are rotated by transmitting power from a two-horsepower electric motor at a line voltage of 380 volts; 3 phase; 50 hertz.
- The transmission system uses a reduction gear motor, a roller chain and a sprocket. This allows the water spraying buckets to scoop water at five revolutions per minute and at a depth of 0.50 meters below the water surface, and to spray water above the water surface at a height of 1 meter.
The functioning of the water spraying buckets creates a large interface area between water and air, resulting in oxygen being quickly absorbed into the water. When waste water is scooped up, exposed to air, and then released, it creates air bubbles which eventually drop below the water surface. As each water spraying bucket rotates and presses down into the water, it causes air to compress in the bucket under the water surface until the bucket completely submerges in the water. This increases the effectiveness in transferring oxygen.
After oxygen has been added, the bucket will propel water at a low of 0.20 meters per second in order to push water away from the aerator at a distance of 10 meter. A by-product of the aerator is achieved from the movement of the floating vessel which causes the hydrofoil assy to stir and mix water with oxygen below the water surface. This movement simultaneously brings about a series of activity like adding air, stirring water in an integrated manner, and controlling the flow of waste water in a horizontal direction.
