Process water treatment

Lignin dispersants can be added to process water to prevent agglomeration of the undissolved suspended particles.

If process water contains non-soluble components, there is often a danger of agglomeration of these particles as well as the buildup of deposits on plant components through which the water is conducted. This can lead to disruptions in the process water cycle and disruption of the overall process.

To eliminate or minimise these effects, lignin dispersants can be added to the process water to prevent agglomeration of the undissolved suspended particles. Lignins act like anionic tensides and also feature high thermal load as well as high stability in the acidic and basic pH range.

Lignin is a major component of wood and is one of the most abundant natural organic wood polymers which provides a multitude of functionalities.

Our lignin is used in a variety of industrial and agricultural areas for various applications.
