Cascada™ AN-Water System: Rinse Up After Fitting New Cartridge Pack

The cartridges in the Cascada AN-water System are operated in a twin-pack system. When the primary pack is exhausted, it is replaced by the pack from the polishing position and a new polishing pack is fitted. The new pack is rinsed and allowed time to reach optimum performance. Resistivity was 18.2 Mohm-cm in less than 10 minutes. TOC was within specification (< 2 ug/L) after 6 hours.

The Cascada AN-water System was fed with Reverse Osmosis (RO) permeate and an Anatel A1000 TOC analyzer was connected to record TOC and resistivity values. After the new pack was fitted, the unit was left to recirculate with the analyzer connected.
