ABSTRACT:
In a biological water purification process dirty water such as sewage percolates through a submerged bed of activated carbon under aerobic conditions, the carbon particle size and the water flow rate being such that the time of contact of the water with the mass of carbon above an intermediate level of the bed is at least thirty minutes, oxygenation air being blown into the bed at this intermediate level so that the mass of carbon below this level remains substantially free of active colonies of bacteria. The bed can be reactivated as desired by flushing with clean water and then with dirty water to re-establish bacterial colonies.
