It may be performed in plants making use of mechanized treatment units much like People employed for industrial wastewater.
The two of such treatments are generally furnished in prefabricated steel tanks termed package deal plants. Oxygen aeration systems combine pure oxygen with activated sludge. A richer concentration of oxygen allows the aeration time and energy to be shortened from 6 to two several hours, reducing the expected tank quantity.

This transpires with a comparatively high stream velocity of about 0.3 m/s. A difference is manufactured in between the non-aerated extensive sand collector, the aerated prolonged sand collector – also called a cylindrical sand collector –, as well as spherical sand collector.
