Real-life use cases on control practices and impacts before and after TDS technology implementation in brown stock washing

Brown stock washing
Liquid Measurements

In this webinar, Rick Van Fleet (Andritz Process Optimization, Global APC Owner) will discuss the latest developments in fiberline brown stock washing with real-life use cases. The focus is on how mills have identified bottlenecks and improved economics using Optimized Dilution Factor (DF) functionality. 


In-line Total Dissolved Solids TDS measurement is essential tool to optimize individual brown stock washing steps and the entire process efficiency. The measurement technology has been developed over the past ten years and Vaisala K-Patents TDS technology has a proven track record in achieving major and measurable improvements in washing, cooking, and delignification performance with new types of advanced process control solutions.


Andritz Process Optimization offers expertise and practical solutions for automation and process engineers’ control tasks. The aim is to help mills continually improve their pulping processes, making them more efficient and profitable.

This webinar is the third in a series of three.
