Abstract
Abstract To prevent, as far as possible, malfunction of a dental evacuation system, portions of a free-flowing additive are added at intervals to at least one constituent of the liquid-solids mixture. This is repeated several times during each period of operation of the evacuation system within the first evacuation section, which includes the separator (1). The additive added in portions may be, for example, a disinfectant, a cleaning agent and/or an anti-foam agent.
