With the development of the paper industry and the increasing shortage of available resources, many manufacturers have started recycling waste paper and white water to reduce production costs and minimize environmental pollution. This inevitably brings a large number of bacteria into the paper machine system. During the pulping and paper-making process, the pulp contains abundant nutrients such as carbohydrates and proteins, which promote microbial growth. Under suitable temperature and humidity conditions, foreign microorganisms rapidly proliferate within the system, leading to the formation of degraded pulp (corrupt pulp) in various equipment and pipeline systems through which the pulp and white water flow. Corrupt pulp can severely impact the production process and product quality. The addition of biocides and preservatives to the pulp, coating, and wet-end systems of paper machines can significantly inhibit microbial growth, improving paper quality and ensuring smooth production operations. Henning offers a wide range of biocides, preservatives, and fungicides for the paper industry, effectively controlling various microbial issues in the paper-making process!
