Mechanism of a/the drain processing place

1. it flows from the under waterway to the airation tank.
2. it revolves the middle of the airation tank around.
3. as for the middle of the tank the clump (the activity sludge) of the microorganism, is doing lightly. When that is stirring, putting in air the microorganism changes what to the water eating beautiful dirt with a bang.
4. the clump of the creature sets downward, when it is doing it quietly in the final deposit pond, and the top is beautiful water.
5. sterilizing the top it pours it to the river and the sea.

In the deposit pond and also the clump of the depressed creature is returned to the tank. (Return sludge)
The microorganism is disassembled in the sludge decrease volume institution, because increase quickly and eat dirt and be returned to the tank.
Also, the creature (the surplus sludge) that too much increased is changed to the compost fertilizer through, dehydration/fermentation and be used in agricultural land.

Return
