Abstract
A method and apparatus for removing particulate matter suspended in low conductivity liquids employs extrinsic ions to electrically charge suspended particles. A unipolar current of the extrinsic ions is passed through the flowing liquid to efficiently charge the particles. The charged particles may then be removed by agglomeration and sedimentation techniques, or by other means. A stripping section is disposed upstream of the region in which the particles are charged, in order to strip the double layer of counter ions from the particles before the particles are charged.
