METHOD FOR KILLING AND REMOVING MICROORGANISMS AND SCALE USING SEPARATION UNIT EQUIPPED WITH ROTATING MAGNETS

摘要

A method to continuously clean a fouled process stream using a magnetic field comprising feeding the fouled process stream (10), comprising a fouling constituent, to a magnetic separation unit (100). The magnetic separation unit (100) comprising a separation vessel (105) configured to receive the fouled process stream (10), a mounted magnet (130) configured to generate the magnetic field operable to reduce a concentration of the fouling constituent. The mounted magnet (130) comprising a magnet motor (132) configured to rotate a shaft (134), the shaft (134) configured to rotate a magnet (136), and the magnet (136) configured to generate the magnetic field. A circulation pump (120) is fluidly connected to the separation vessel (105) and a sampling point (110) configured to allow removal of a sample. The method further includes measuring the concentration of the fouling constituent in the sample and supplying an effluent stream (18) from the separation vessel (105) to a clean collection vessel (400).
