Why can paper-making bactericides save water and reduce emissions
Due to the complexity of microbial growth, the diversity of papermaking processes, and regional differences, simply adding industrial papermaking biocides often fails to address microbial issues in the papermaking process. To effectively control the excessive proliferation of microorganisms in the paper machine system, it is necessary to fully consider various factors such as microbial species, water quality, pulp type, paper type, flow rate of the paper machine, and its cleanliness. Next, the editor from Xiangze Chemical will introduce why papermaking biocides can save water and reduce emissions:
Currently, the main methods for handling anionic trash include: firstly, treating white water through mechanical and filtration methods, such as flotation, ultrafiltration, and nanofiltration; secondly, addressing it from the wet-end chemical process. However, treating white water not only incurs high costs but also makes it difficult to completely separate harmful substances. Therefore, the best method to address anionic trash is to use chemical additives, such as resin barrier control agents, papermaking bactericides, anionic trash capture agents, and retention and drainage aids. Through the principles of charge neutralization, patching, and bridging, these harmful substances are fixed on the fibers, allowing them to leave the wet-end system together with the paper instead of accumulating in the white water. This increases the reuse frequency of white water and reduces the amount of fresh water used. At the same time, the concentration of white water decreases, which also reduces its pollution load, ultimately achieving the goal of water conservation and emission reduction.
