Plant grass on your own drainfield, but preserve trees and shrubs away from it, because roots can clog the system and cause damage.

The oxygen helps the microorganisms to digest the pollutants speedier. The water is then taken to settling tanks the place the sludge yet again settles, leaving the water ninety to ninety five per cent here freed from pollutants.

In this particular feeling, the driving forces are: tension difference; concentration big difference; partial force change or electrical potential distinction.

The microorganisms sort activated sludge flocks that float freely in the water. The supply of oxygen stimulates the multiplication of germs and thus promotes the formation of activated sludge.
