Brief Introduction:

AU-PE89 acts as a pre-bleaching aid for paper pulps. AU-PE89 has specific advantages in that it is stable and active at the alkaline pH and elevated temperatures typical of kraft pulps. The main driving factors for acceptance of this technology in pulp mills have been the economic and environmental advantages over chemical bleaching.

Packing:

25kg/drum in bulk

Dosage

40-50g/ Ton pulp

Advantage:

1.Reduce Organochlorines in Wastewater:

For mills using active chlorine as a bleaching chemical, AU-PE89 can eliminate or substantially reduce the chemical and environmental load of toxic organochlorines in mill effluent.

2.Reduce Chemical Costs:

For mills using environmentally friendly bleaching agents such as hydrogen peroxide, AU-PE89 can result in a significant cost saving.

AU-PE89 has the potential to reduce bleaching chemical by15 to 50%.

3.Increase Pulp Production Capacity:
Pre-bleaching pulps with AU-PE89 allows pulp production capacity to be increased where on-site chlorine dioxide production is a limiting factor.

4.Higher Pulp Brightness:

For a given dosage of bleaching chemical, pre-bleaching with AU-PE89 can give a higher brightness pulp, thus providing the mill with

a better quality paper.

AU-PE89 can increase the pulp brightness by 2 to 6%.

5. Easily Incorporated:

AU-PE89 is easily incorporated into existing bleach lines. Typically, installation requires only a mixing tank and dosage pump.

6.Reduce Effluent Load:

Application of AU-PE89 in the bleach plant can reduce COD, BOD and color of effluent.

AU-PE89 can significantly reduce COD, BOD and color of effluent. 

Storage:

AU-PE89 maintains its stated activity for at least six months when stored at temperatures below 25°C. The product maintains its activity for considerably longer when stored at lower temperatures. The product should not be frozen.
