Supply of water, aeration and removal of solid wastes

As shown in the photo the supply of water is done at an angle of 45o. Placing the aerators at the same angle helps to circulate and move tank water in one direction which will lead to better oxygenation of tank water as well as to get rid of solid wastes. The circular movement of tank water as shown in the second photo leads to the concentration of solid wastes at the tank center which will be easily discharged along with tank waters and eliminating the need for mechanical filters.

Note: We decided not to watermark the photos in order not to upset its clarity. However, we trust you will notify us if you wish to use a picture or more. This is expected and will be appreciated.
