【Abstract】 The presence of dissolved and colloidal substances(DCS) in the process water of deinked pulp may increase the chemical consumption in the wet end and affect the runnability of the process.The advantage of enzymatic treatment of DCS is due to the specificity of the enzyme catalysis.In this paper the suitability of different enzymes,including laccase,lipase and pectinase,for DCS control are discussed.更多还原
