Abstract
The object of our work was to study the influence of the bacterial activity in granular activated carbon filters on the removal of biodegradable and non-biodegradable organic compounds. To this end, experiments were carried out with one-solute and bisolute solutions of organic compounds. In the first part of our survey performed under sterile conditions, adsorption capacities and adsorption kinetics were determined from batch experiments. The influence of the competitive adsorption on the breakthrough curves was shown by means of dynamic tests. In a second part, filtrations of a mixture of a biodegradable and of a non-biodegradable compound were performed in two micro-columns in order to study the influence of the biodegradation in the removal of organic matter.
