Black liquor is generally the waste water produced after the caustic soda process is used in papermaking, pulping, washing and other links, which contains a lot of lignin, organic acids, etc., and also contains a part of solid suspended matter. Due to the complexity of the papermaking process, there will be more or less some foam problems in different production links, and if the foam is not eliminated in time, it will have a certain impact on the subsequent process.

The Hazard of foam in pulping process:

1. Add bleach and other chemical additives in the process of papermaking and pulp washing to react with the chemical components in the black liquor, which will produce foam; 

2. Contaminants such as fatty acid salts and hemicellulose contained in black liquor have high viscosity and are not easy to degrade. They are the basic components of surfactants themselves, which reduce the surface tension of aqueous solution and are easy to foam; 

3. Due to the presence of excessive alkali, incomplete precipitation of slurry fermentation and other reasons, resulting in black liquor foam;

4. The vibration mixing of the beater and other machines makes the black liquid foam.
