1st and 2nd stage tanks.Functionally these tanks are identical.
The 1st stage tank receives from the screened sewage inlet
In this image you can also see the settled sludge pickup on the floor.
In operation both 1 & 2 tanks contain the bacteria which colonises the proprietary Bio-Xpress Media. (see image above) There is around 3 metric tonnes floating free in a model 700. Each piece is approximately 12 mm in diameter and is designed to provide the maximum surface area for the microbes that do all the hard work.
They simply feed on the raw sewage destroying pathogens, suspended solids and contaminents. They do this whilst consuming oxygen provided by the continuously running aerator.
The Bio-Xpress Media is continually agitated by the action of air passing through the diffuser tubes.
The macerated and processed sewage (effluent) is then passed to the 2nd stage tank via upper and lower screens.
The sludge pickup continually collects the heavier sludge in both tanks which is passed through the Cyclone in the Control Station where it is separated over and over until it can be safely removed as Biosludge .
The 2nd stage tank continues this process and passes the further refined effluent through the upper screens and on to the 3rd stage tank.
