Abstract
The waste water reclamation system using a rotating membrane UF module, has beenstudied by adding a powdered activated carbon to a biological treatment process to remove the organic colored matter.
In this system, the powdered activated carbon dosage of 50 mg/l, and retention time of 4.5 hours, have been required to stably obtain a treated water with the color of less than 5 degrees.
It was found that the activated sludge filterability could be improved by adding the powdered activated carbon and the rotating membrane UF module could operate at a permeation flux of 1.0m3/m2 d for about one and half years.
