Green liquor handling

In this process the dregs are separated from the green liquor. In turn, the dregs are washed and dewatered.

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 clarifier, Valmet Green Liquor Clarifier and ultra-compact "all-in-one" Valmet Green Liquor Disc Filter.

Valmet Green Liquor Clarifier

The high rate clarifier allows for a more compact footprint by improved internal distribution and effective use of polymer, while giving better process results than the traditional clarifier.
