Abstract
This study aims to develop an economic process for the treatment of industrial wastewater containing hydrogen peroxide by using catalase. Core process is characterized by two membranes; microfiltration membrane and ultrafiltration membrane with different molecular cut-offs. Optimum dilution ratio of Aspergillus niger molds 개 buffer solution is 1:5. The final recovery yield of the enzyme is over 90% using the process. The enzyme solution shows the optimum temperature of 4$0^{\circ}C$ and pH range of 5-8.
