Method for flushing particle-bearing filter beds, to sterilise and decontaminate the same

摘要

Flushing particle-bearing filter beds using an aqueous solution containing chlorine oxide and/or halogen and/or peroxide to remove the reaction products caused by the process and any residual chlorine oxides or halogens or peroxides. Sterilization and decontamination of particle-containing filter beds in linear or circuit water-treatment plant comprises first treating with a chloroxide-, halogen- and/or peroxide-containing aqueous solution and then rinsing with water or an aqueous medium.
