Lignin modification/wastewater treatment



Lactase can be used in lignin modification and wastewater treatment, which can improve the wet strength of mechanical slurry and reduce the color of wastewater and BOD/COD.



Hydrogen peroxide control



Catalase can monitor and optimize the amount of hydrogen peroxide in bleaching. After bleaching, the residual hydrogen peroxide can be degraded by adding hydrogen peroxide enzyme.



Resin barrier control



In the process of making paper with mechanical pulp, the application of lipase in the control of resin barrier can improve the paper strength, reduce the paper sickness, shorten the downtime and reduce the cleaning times of the paper blanket and roller, so as to improve the paper quality and improve the production economic benefits.



Starch modification



Amylase enables the paper mill to modify the raw starch on the spot and apply it on the surface, which is more economical and practical than purchasing commercial denatured starch directly.



The use of xylanase to promote the bleaching of sulphate slurry ECF and TCF can save the bleaching agent and/or improve the whiteness of slurry after bleaching.
