STEP 7 - Secondary Clarifiers

Secondary Clarifier

Those Microorganisms Are Heavy Enough to Settle


Microorganisms ate the sludge out of the water in our basins. The wastewater stayed in those basins for many hours.


From there we pump the water to big tank, another clarifier. In this tank the microorganisms settle to the bottom. The sludge was not heavy enough to settle out of the water. But the microorganisms are.


This water looks clean enough to drink, but it NOT drinking water! We only make water for the river at our plant.
