Floating paddle wheel aerators
Floating paddle wheel aerators are very popular in semi-intensive shrimp farms. They are considered as one of the most energy efficient device for increasing dissolved oxygen. They splash water into the air as the paddle wheel rotates. The splashed water comes in contact with air and falls back into the pond and thereby increasing the dissolved oxygen. Besides increasing the dissolved oxygen they also increase both horizontal and vertical movement of pond water. The amount of oxygen that is transferred to the water increases with size and speed of paddle wheel.
