AlpHa Measurement Solutions | Oxidation-Reduction Potential (ORP) in Pulp & Paper
ORP in Pulp & Paper
The use of oxidation-reduction potential (ORP or REDOX) measurements in pulp and paper applications primarily involves chlorine injection (bleaching and disinfection) and oxidizer use. ORP monitoring can deliver real-time results enabling quick response and reduced downtime. Monitoring oxidation or reduction reactions can be useful at various locations in the production of pulp and paper:
Color Control in Paper Products
Alert Operators to the Presence of Reducing Agents
Monitor and Control of Oxidant Addition for Disinfection
Waste Characterization for Treatment and Reuse Strategies
Most ORP measurements are performed in a continuous measurement application. Due to the harsh environment of the pulp and paper production process, ORP sensors require robust material sensor designs. AlpHa can provide custom design inputs including Tuff-Tip (AlpHa specific design for pulp and paper applications) reference junctions and mechanical assemblies.
