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
