Pulp sanitation is the primary guarantee for producing food-grade, medical-grade and high-end household paper. In the pulping and circulating production process, pulp is prone to microbial contamination, residual organic impurities and peculiar smell breeding due to long-term contact with circulating water and external environment. Unsanitary pulp will lead to paper mildew, bacterial exceeding standard and residual odor, which directly fails the hygiene inspection of sanitary paper, food packaging paper and medical paper. Poor pulp sanitation not only restricts product grade upgrade but also brings potential health and safety risks, making it impossible to enter high-end hygiene product markets. Conventional single disinfection methods have short duration, cannot remove organic odor sources thoroughly, and easily produce disinfection by-products affecting paper safety. Shandong Ludao Energy Technology Co., Ltd. provides integrated pulp sanitation optimization and purification solutions. Through efficient microbial inhibition, organic odor decomposition and impurity purification technology, we thoroughly improve pulp cleanliness and sanitation level, eliminate hidden dangers of bacterial reproduction and peculiar smell residue. The solution is non-toxic, harmless and environmentally friendly, does not affect paper physical performance and printing effect, enables pulp to meet strict medical and food-grade hygiene standards, and helps enterprises develop high-safety high-end sanitary paper products.
