Optimizing peroxide consumption
Catalase is a simple means to optimize the amount of peroxide used while still ensuring that the desired pulp or paper brightness is achieved. Removing excess peroxide both offers a direct cost saving and reduces the corrosion risk that peroxide poses.

The plant operator checks the level of peroxide present by applying the enzyme in a test performed on a sample of pulp. The operator can then adjust the input of peroxide accordingly.

Removal of residual peroxide
After bleaching, i.e. before downstream processing or in the effluent, the presence of residual peroxide may have adverse effects downstream or a negative impact on environment. Applying catalase can reduce this risk.

The enzyme acts as a catalyst for the conversion of hydrogen peroxide into water and oxygen. Peroxide discharged with effluent can be harmful to water plants and bacteria.

Catalase is a simple tool for optimising peroxide consumption when bleaching pulp. The enzyme is also used to remove residual peroxide after bleaching.

The catalase enzyme improves pulp peroxide bleaching processes by:

• optimising costs
• reducing corrosion caused by excess peroxide
• degrading residual peroxide
