Abstract

PURPOSE: To perform agitating of active carbon uniformly and remove suspended matter by providing the backwashing air supply pipes which are pierced with plural injection holes disposed nearly equally in their cross sections and are disposed at nearly the same space between them, to the under side of the active carbon bed.
CONSTITUTION: When layers of suspended materials are formed in the activated carbon bed and its water permeability degrades, first a feed water supply pipe 9 and a treated water discharge valve 12 are closed then a backwashing water supply valve 16 and a backwashing water discharge valve 14 are opened. While a flow rate regulating valve 11 is being regulated, the backwashing water is supplied to the lower part of an activated carbon adsorption tower 1 through a backwashing water supply pipe 17. At the same instant, a backwashing air supply valve 18 is opened to eject the compressed air from the plural injection holes 20 disposed nearly equally in the cross section of the bed, thereby uniformly agitating the active carbon bed 4. The suspended materials etc. in the activated carbon 4 are discharged through the valve 8 then through a backwashing water discharge pipe 15 and a backwashing water discharge valve 14.
