Paper & Pulp industry is characterised by the large use of auxiliary chemicals, high organic/inorganic load in wastewater and a constant quest to improve pulp yield. Chemical technology has reached a saturation point and this is where the technology of “Probiotics” steps in to address these specific challenges.
The first product from ProCharta for the Paper & Pulp industry is “ProWhite”. It enhances delignification and improves bleaching of pulp due its ability to effectively prevent transition metal ions from hindering the performance of process chemicals and auxiliaries. Mechanical properties such as viscosity, tear strength etc., are seen to improve on application of ProWhite even while there is a drop of 10 to 15 % in effluent parameters such as BOD, COD, SOR etc.,.
Next in the pipeline:
ProCharta has identified other application areas in Pulp & Paper where the technology of probiotics can be successfully applied;
c) Cooking Digester Aid
d) Surfactant and dispersant for pulp washing
e) Dispersing agent for dyes
Delignification & Bleaching Agent
ProCharta ProWhite is a path breaking product based on the platform of ‘Probiotics’ for the Paper & Pulp Industry to enhance delignification and bleaching. ProWhite due to its powerful ability to inhibit transition metal ions, optimises the use of Chlorine Di-oxide, Caustic, Hydrogen Peroxide, Hypo etc.,.
It results in reduced requirement of these chemicals even while improving delignification and enhancing whiteness / brightness. ProWhite also helps in lowering effluent load – parameters such as BOD, COD, AOX, SAR etc., are seen to be lower by upto 15%. Mechanical properties such as viscosity, tear index, double fold, fibre length, etc., are also seen to be improved. ProWhite is versatile in its application and delivers results across all types of raw materials (hard wood, agri waste etc.,) and processes.
- Saves Operating Costs: Reduction in use of chemicals such as Chlorine di-oxide, Caustic and Peroxide leads to direct cost savings
- Reduces Pollution Load: Effluent parameters such as BOD, COD, SAR, AOX etc., are seen to be lower by 10 to 15 %
- Improves mechanical properties: Parameters such as Viscosity, Tear strength, Fibre length and Double Fold show improvement.
- Higher Yield: Reduction in bleaching chemicals and improvement in viscosity tend to indicate higher pulp yields
ProWhite is dosed at the rate of 100 grams per tonne of pulp at delignification stage and 50 to 100grams per tonne in individual bleaching stage.
