Abstract
A method for reducing a production of a build-up slime in a papermaking process is provided. The method includes steps of adding a dispersing agent into the papermaking material to obtain a first mixture, mixing and culturing the first mixture, adding an antagonist into the first mixture to obtain a second mixture, mixing and culturing the second mixture for reducing the production of the slime, and re-adding the antagonist into the mixed and cultured second mixture after a specific time period for further reducing the production of the slime.
Claims10
A method for reducing a production of build-up slime of a papermaking material consisting essentially of a white water and a waste paper pulp in a papermaking process, comprising steps of:
- inhibiting an adhesion between a slime-producing microorganism and additives during the papermaking process by adding a dispersing agent into the papermaking material to obtain a first mixture;
- mixing and culturing the mixture;
- adding an antagonist into the first mixture to obtain a second mixture;
- mixing and culturing the second mixture for reducing the slime;
- and
- re-adding said antagonist into the mixed and cultured second mixture after a specific time period for further reducing the slime, wherein said antagonist is a benefit microorganism being Streptomyces bikiniensis.
A method for reducing a production of build-up slime of a papermaking material consisting essentially of a white water and a leaf bleached kraft pulp in a papermaking process, comprising steps of:
- inhibiting an adhesion between a slime-producing microorganism and additives during the papermaking process by adding a dispersing agent into the papermaking material to obtain a first mixture;
- mixing and culturing the first mixture;
- adding an antagonist into the first mixture to obtain a second mixture;
- and
- mixing and culturing the second mixture for reducing the slime, wherein said antagonist is a benefit microorganism being Streptomyces bikiniensis.
A mixture for reducing a production of build-up slime in a papermaking process, comprising:
- a papermaking material consisting essentially of a white water and a leaf bleached kraft pulp;
- a dispersing agent for avoiding adhesion between a slime-causing microorganism and other additives in the mixture;
- and
- an antagonist being a benefit microorganism Streptomyces bikiniensis.
