Abstract
En innretning basert på flotasjonsmetoden (DAF) med trykkvann, hvor dispergeringsvannet og vannet som skal behandles, f.eks. flokkulert vann, tilføres et reaksjonsrom (1) hvor de møtes og reagerer med hverandre. Innlpsledningen (8) for vannet som skal behandles er konstruert i forbindelse med et reaksjonsrom (1), slik at avstanden mellom åpningen (11) i innløpsledningen (8) og bunnen (2) av reaksjonsrommet kan reguleres ved å flytte innløpsledningen. (8) i retningen b for reaksjonsrommets midtakse (13), hvorved møtested og måte (turbulent, jevn) for dispergeringsvannet og vannet som skal behandles, f.eks. flokkulert vann, inne i reaksjonsrommet, kan justeres alt etter de aktuelle prosessforhold.A device based on the flotation method (DAF) with pressurized water, where the dispersing water and the water to be treated, e.g. flocculated water, is fed to a reaction chamber (1) where they meet and react with each other. The inlet line (8) for the water to be treated is designed in connection with a reaction space (1), so that the distance between the opening (11) in the inlet line (8) and the bottom (2) of the reaction space can be regulated by moving the inlet line. (8) in the direction b of the central axis of the reaction chamber (13), whereby the meeting place and manner (turbulent, even) of the dispersion water and the water to be treated, e.g. flocculated water, inside the reaction chamber, can be adjusted according to the relevant process conditions.
