Raindrops Water Technologies can design and make mixed bed polishing units to suit all of customer’s need.
Cation and Anion resins are combined in a MSRL of FRP vessel to produce ultra pure water.
Usually a mixed bed unit contains strong acid Cation (SAC) resin and strong base Anion (SBA) resins combined to a ratio of approximately 40% Cation resin to 60% Anion resin. (All resin volumes are dependent upon the feed water analysis and the required quantity of treated water).
Mixed bed polishers are typically installed when a water quality of less than 1 micro ohm conductivity is required. Normally mixed bed polishers are installed after a standard Reverse Osmosis or De mineraliser (DM Plant), to produce ultra high quality water.
The Cation resins in mixed bed units are of a higher specific gravity and settle at the bottom of the vessel at the same time the Anion resin will automatically float to the top.
Please note: The Cation resin must be a strong acid Cation type (SAC) and the Anion resin must be a strong base Anion resin (SBA)
After a service cycle, each resin is regenerated as below:
Please note: The above regenerate strengths refer to the values before being diluted by the mixed bed unit educator systems.
