METHOD AND INSTALLATION FOR PURIFYING A LIQUID PRODUCT

摘要

A method for continuous purification of a liquid comprises inserting the unpurified liquid into a reaction tank, injecting at least flocculants for flocculating impurities and air into the unpurified liquid, retrieving a flocculated unpurified liquid containing air from the reaction tank at a first extraction location below the injection location, transporting the flocculated unpurified liquid containing air towards a flotation tank, adding a polymer to the flocculated unpurified liquid containing air, inserting the flocculated unpurified liquid containing air and polymer into the flotation tank, removing a sludge comprising flocculated impurities from the flotation tank either continuously or during predefined time intervals, and continuously extracting at least partially purified liquid from the flotation tank. The method can be carried out by the disclosed installation.
