    Redefine brown stock washing (BSW) ROI

    You may be stuck in a vicious cycle of trying to obtain a cheaper BSW defoamer, but it comes at the expense of your overall washing costs. This is because you’ve looked at your core problem as suppressing foam at the lowest possible cost. But it’s really about how you can drive the highest return from your pulp washing.

    The most successful mills are realizing that to be viable in this challenging market, you need to break the foam cycle. That means uncovering what’s really impacting washing performance, with the expertise to solve problems at their source. And it means redefining successful pulp washing around increased drainage and exit consistencies, so you can drive long-term improvements across your entire process.

    When you shift your thinking from cheap foam knockdown to efficient washing, you’ll optimize energy usage by using less wash water and reducing evaporator load. You’ll improve the quality of your product, while lowering bleaching costs and soda losses. And, you’ll supercharge your process to drive more throughput without having to spend capital on equipment. This is how you position yourself to stay ahead of the market’s ever-changing demands.
