BTG releases online charge instrument
October 15, 2019 By P&PC Staff
BTG has launched an online charge instrument called Single Point Charge SPC-5500.
Its single point modular design allows for greater flexibility than previous models.
The SPC-5500 is suitable for wet-end applications in all paper-making processes such as in tissue, packaging and board or specialty paper. It is used to control key process stages like anionic trash levels in incoming thick stock streams, especially for closed loop control of fixatives. Furthermore, the effectiveness of functional additives dosed along the process can be evaluated through charge measurement.
The SPC-5500 continuously measures the charge of colloidal dissolved substances in process streams. Cationic demand or anionic demand is detected by automatic titration of the sample with an oppositely charged poly-electrolyte solution. Each measurement cycle follows a cleaning which is a basis for correct results.
The BTG Group is an international provider of integrated, highly specialized process solutions for the global pulp and paper industry.
