Green liquor handling

Valmet offers products that separate dregs from green liquor and increase the efficiency of the recausticizing process. The dregs handling encompasses systems that wash and dewater dregs efficiently with minimal or no mud consumption. Valmet has several green-liquor handling equipment alternatives, which all meet the primary aim, to reduce the dregs content. The products range from traditional clarifiers to high-rate clarifiers, Valmet Green Liquor Clarifier and ultra-compact "all-in-one" Valmet Green Liquor Disc Filter.
