Removal of biofilm from activated carbon in industrial adsorption filters

The mechanism of removing biofilm and other adsorbed substances from activated filters used for the advanced wastewater treatment was investigated. It was found that the maximum removal of pollutants—up to 0.18 g/100 cm 3 for insoluble substances and up to 160 mg/cm 3 for the total organic carbon—wa...

Zusammenfassung:	The mechanism of removing biofilm and other adsorbed substances from activated filters used for the advanced wastewater treatment was investigated. It was found that the maximum removal of pollutants—up to 0.18 g/100 cm 3 for insoluble substances and up to 160 mg/cm 3 for the total organic carbon—was obtained through the two-stage treatment, first, using 1M NaOH solution, and then, 0.85% NaCl. The use of 0.85% NaCl following the Ringer’s solution was found to be the most efficient way in de-immobilizing living biomass—up to 310 CFU/cm 3 was removed.
