The Role of Defoamers in Pulp, Paper, and Concrete Industries

Sep 18, 2025
Foam formation is a common issue in industrial processes such as pulp and paper manufacturing and concrete production. Excess foam not only disrupts production efficiency but can also compromise product quality and increase operational costs. To address this challenge, defoamers are widely applied, providing an effective way to control unwanted foam and maintain stable performance across different industries.
In the pulp and paper sector, foam tends to form during pulping, bleaching, and wastewater treatment processes. This foam can reduce drainage efficiency, affect paper formation, and slow down machine speeds. By introducing specialized defoamers, paper mills can enhance operational stability, improve water recycling, and ensure consistent paper quality. Similarly, in wastewater treatment units of paper mills, defoamers play a vital role in controlling surface foam, preventing overflow, and supporting compliance with environmental regulations.

In the concrete industry, defoamers help control entrapped air during mixing. Excessive air bubbles can weaken the strength and durability of concrete structures, leading to cracks and reduced stability. The right defoamer ensures optimal air content, resulting in improved compressive strength, smoother finishes, and longer service life of concrete products. This makes defoamers a critical additive for construction companies aiming for reliability and safety in large-scale projects.

When it comes to choosing a reliable solution, Rickman defoamer stands out.
