Defoamers
Foam control is important to achieve good deaeration and defoaming in the paper-making system to optimise formation and drainage.
Typically, water based defoamers (aqueous dispersion of hydrophobic materials) are used in the paper making process and are found efficient for deaerating the white-water. Depending on paper quality also other types of water free defoamers can be applied. Selection of the best suited defoamer often starts with a screening of products in the laboratory and testing of the specific white-water concerned.
