| 摘要 |
An ionization delivery unit suitable for introducing microbicidal metal ions into an aqueous fluid comprises an inner cylindrical electrode surrounded by a cylindrical outer electrode disposed to provide a flow path generally shaped as a hollow cylinder, aqueous fluid introduced into the flow path by an inlet which imparts a substantial tangential component to the fluid flow. The vortexing flow encourages even electrode wear and minimizes deposition of occluding substances on the electrodes. The inner electrode is preferably a copper/silver anode while the outer electrode is preferably a stainless steel.
