PCT No. PCT/GB90/01456 Sec. 371 Date May 14, 1992 Sec. 102(e) Date May 14, 1992 PCT Filed Sep. 20, 1990 PCT Pub. No. WO91/04486 PCT Pub. Date Apr. 4, 1991.Devices and methods for sensing the charge condition of a mixed stream of aggregant and aqueous dispersion of charged particles are based on sensing changes in the potential of an electrode contacting the stream. Sensing the changes in potential permits better control of aggregation in raw water and effluent treatments. |
