Aereation equipment Dhiwoll D-5000, are simple design equipments whit a high oxygen transfer into the water, these devices deliver a large volume of air in fine bubbles able to obtain a perfect mixture of transferring the required oxygen in the effluent.

The design of these machines is the injection of air using a blower which in injected through the downstream propeller on achieving a fine bubble size that is injected into the mass of water to be treated in a homogeneous
