Process for reducing slime and deposit formation in (partly) closed systems conveying water or aqueous media, e.g. in paper machines or cooling water cycle, involves adding sulfur-free lignin or derivative

摘要

Process for reducing the formation of slime and deposits in (partly) closed systems conveying aqueous media or water comprises adding sulfur-free lignin or its derivative in an amount proportional to the amount of substances causing slime and deposits.
