With high volumes of high soluble organics, pulp and paper wastewater treatment offers a number of challenges. Often treatment systems experience issues related to the high carbon to nitrogen/phosphorus ratio and low dissolved oxygen from high organic loadings. The influent favors the growth of filamentous bacteria that cause problems with TSS removal in clarifiers or settling ponds. Aster Bio has developed microbial formulations to address the most common challenges facing pulp and paper wastewater treatment.
- AB Lignozyme – general blend for BOD/COD removal & degradation of cooking liquor/plant soap components
- AB Lignozyme BP (Biopolymer producing blend for filament/TSS control)
- AB Lignozyme S (Blend with sulfide oxidizers for better odor and septicity control)
