Carrousel 3000 is also called the space solution; this feature of carrousel has the "deep" solution. This material offers the luxury of water depths of up to 8 meters. Thus this technique reduces the needed surface of land When the surface aerators are equipped with draft tubes, depths of the aeration zone of up to 8meters can be realised, resulting in a considerably reduced footprint.A draft tube is avertical cylinder underneath an aerator, which extends almost down to the bottom. It enables the aerator to draw (oxygen deficient) water from the bottom of the tank, thereby ensuring proper mixing over the entire tank depth. This principle has proven to work well in practice for rectangular aeration tanks. However, the necessary propulsion effect of an aerator in aCarrouselbasin is greatly reduced by the draft tube. This is overcome by installing additional propulsion means, propellers, in the channels of theCarrouselbasin. Carrousel 3000 still combines the ideal features of the original Carrousel and Carrousel 2000.

The Carrousel 3000 system before the Carrousel 2000 system coupled with a biological selection area. The biological selection area is the uses of high organic loading filter bacteria, inhibit the growth of filamentous bacteria, improve the removal of pollutants, the subsequent process principal with the Carrousel 2000 system.

Improved performance in the Carrousel 3000 system: One is to increase the pool depth up to 7.5 ~ 8m, concentric circles, shared wall, reducing the footprint, reduce the cost while improving the low temperature tolerance (up to 7 ° C); clever design of the aeration equipment, surface aerators installed draft tube, suction mixture of oxygen, the use of underwater propulsion solve the flow rate problem; Third, the use of state-of-the-art aeration controller Qute (it the use of a multi-variable control mode).Fourth, the use of integrated design, starting from the centre, including the following cyclic continuous process unit: into the wells and for the return activated sludge trap; consists of four parts selection pool and anaerobic tank.This is outside the three-aerator and a pre-DE nitrification tank Carrousel 2000 system (Figure 2).Fifth round integration design makes the oxidation ditch without additional pipeline, you can return sludge allocated between the different process units.

i would like a auto cad design of a waste water plant using Carrousel 3000 to have a capacity of 25000m3 of water above is a brief insight about the carrusel 3000 just as a guide measurements may be made up depending on the suiability
