Thread Content

Hi, in the papermaking process (including the treatment of recycled paper), where is caustic soda used in my operations? What are the detailed steps? What are the precautions?

Different, adjust pH? Could you explain the waste paper recycling process?

Adjust PH? I just want to know, in the pulp-making stage of waste paper recycling and processing – namely slag removal, pulp washing, and bleaching – where exactly is the acid value adjusted?
