Rethinking raw water preparation toward more efficient paper making, PaperCon2017

The global demand for water is increasing and the pulp and paper industry will need new solutions to reduce water consumption and increase water reuse and recycling.  As paper mills move toward water closure, the quality of incoming mill water becomes even more important.  Low levels of microbial contamination can become significant once they are recirculated in paper process water.  If not properly controlled, problems caused by microorganisms can lead to unscheduled downtime, raw material loss and reduction or loss of product due to defects or odors in the finished sheet.  Traditionally, microbial control in the process has been challenged by variations in the quality of incoming water, leading to reactive and inefficient microbial treatment.  Minimizing microbial contamination in the incoming water is essential for maximum process efficiency and consistent product quality.  This paper will describe how a holistic water management approach combined with tailored treatment strategies and system monitoring prepare water for more efficient paper-making.
