Stickies Treatments of Recycled Fiber Pulping Wastewater by Lipases

Abstract:

Two types of lipases were employed to control the stickies troubles of recycled fiber pulping wastewater in this article. The conditions of enzymatic treatments were optimized and FTIR and GC-MS were used to characterize the changes between the initial and treated wastewater. The optimized conditions of Resinase(R) were: 20u/100mL, 50°C, pH 6.5 ,2h; and those of Lipase(S) were: 15u/100mL, 50°C, pH 9.0 and 2h. Results confirmed that under these optimal conditions of each lipase, both of the two lipases show the excellent performance in the treatment of the stickies of wastewater.
