Vacuum and dewatering systems are crucial for papermaking, as they contribute to sheet formation, press performance, felt conditioning and general machine efficiency.
In spite of that, paper machines usually operate paying little attention to vacuum processes, until these systems tend to evolve into lost performance, often resulting in reduced dewatering capability, slow or variable drainage, which has a direct and negative impact on overall paper machine efficiency and operating costs.
In the article recently published on Paper Technology International, Andrea Giuntini takes advantage of a Colombian installation to explain how to make the most out of a dewatering and vacuum system.
