MEASUREMENT PRINCIPLE

The instrument incorporates streaming current technology to produce a measurement of electrokinetic charge (ionic & colloidal) using a sample obtained from various points in the process (Headbox Coated Broke Machine Chest Tray Water etc..). The sample is then titrated with a low molecular weight polymer of the opposite charge to bring the sample to a neutral charge. The amount of titrant consumed by the sample is used to quantify the level of charge (anionic or cationic) present in the furnish. The result given as Charge Demand can be used to effectively control the addition of cationic additives (starch polymers coagulants etc..) in order to stabilize charge disturbances. Reducing or even eliminating charge variability stabilizes the wet end and helps optimize and reduce feed rates of expensive additives while also improving er qualities.
