BALANCE TANKS
When all the sewage has been 몭ltered, some treatment plants have speci몭c tanks that house it all and
limit the amount of sewage that can enter the facility at once. This ensures that the treatment is always
of a high standard.
THE BIOREACTOR
The treatment procedure begins when the sewage is released from the holding tanks. One enormous
science e몭ort is sewage treatment. It's a di몭cult procedure, and we need a little assistance from our
good friends, the friendly bacteria. Fortunately, these large, voracious men enjoy eating all the organic
materials in the sewage that we want to remove from the bug.
These creatures consume all the carbon and lower the phosphorus and nitrogen levels in the sewage,
which can have an adverse e몭ect on the health of our rivers. We therefore feed them in enormous
bioreactors that are highly oxygenated.
