K-Patents SAFE DRIVE™ PR-23-SD Process Refractometer for Brown Stock Washing (BSW)

Proper brown stock washing (BSW) lets you fine-tune your process, grow profits, improve pulp quality, and optimize use of water, chemicals, and energy.

K-Patents SAFE DRIVE PR-23-SD Process Refractometer for BSW makes the washing process more efficient by using the least amount of water and wash liquor to separate dirty water and black liquor from pulp fibers.

The refractometer uses Total Dissolved Solids (TDS) as a measurement parameter, allowing it to detect both organic and inorganic compounds while giving real-time updates of your washing process. The SAFE DRIVE design makes sensor insertion and retraction easier and safer to use, and doesn't require a process shutdown. Due to the digital sensing technology, large amounts of suspended solids, bubbles, and color changes have no effect on the accuracy of the measurements.
