Abstract
A method is provided for removing a solid phase from a liquid substance, which is kept in a continuous turbulent flow. The method is characterized by adding simultaneously at consecutive places in the flow direction of the liquid substance, cement, iron (III)-chloride-sulfate and an anion polyelectrolyte. Cement is added at a first place, iron (III)-chloride-sulfate at a second place and anion polyelectrolyte at a third place.
