摘要

There are significant economical benefits associated with replacing fresh shower water with recycled white water in the forming and press section showers of a paper machine. Showers were surveyed on a 390" linerboard paper machine, and a Whitewater conversion risk category of low, medium or high was assigned to each. The savings associated with substituting fresh water with white water in each of these three risk areas has been detailed. Energy savings due to the decreased demand for hot water was found to contribute $3.5 million, or about 77.5% of the total projected savings of $4.5 million for the three risk categories combined. Until the recent introduction of the Petax™ fine filtration system, limitations in solid/liquid separation technology prevented the use of white water in the high risk applications such as the high-pressure showers, which contributes $846k, or about 19% of the total $4.5 million savings.
