RPA-5000: Residual of peroxide

Measure peroxide by using a non-hazardous catalyzer to optimize chlorine-free bleaching agents

The use of chlorine-free bleaching agents in pulp bleaching processes is steadily increasing. Peroxide is the most commonly used of these chemicals for bleaching kraft, mechanical and recycled pulps.

Peroxide, however, is relatively expensive and, therefore, improved control of its use in the bleaching process is beneficial for optimizing operating efficiency and product quality.

Measurement of peroxide residuals after bleaching, for example, is necessary for achieving better overall control of the bleaching process.

The RPA-5000 measures the residual peroxide content of a filtrate sample from a bleached pulp suspension.
