Enhancing Pulp Wastewater Treatment Efficiency with the Right Defoamer

May 15, 2025
Pulp and paper production is a water-intensive industry that generates large volumes of wastewater rich in organic material, fibers, and chemical additives. One of the persistent challenges in treating this wastewater is foam generation, which can disrupt processes, reduce treatment efficiency, and damage equipment. Uncontrolled foam not only hinders aeration and settling but also leads to increased operational costs.
Defoamers play a critical role in mitigating foam-related issues during both primary treatment and biological stages. In pulp wastewater treatment, effective defoamers must not only break existing foam quickly but also suppress foam formation over time. The formulation must be compatible with the chemistry of the system—whether it involves high temperatures, strong alkaline conditions, or biological activity. Silicone-based and polyether-modified defoamers have become popular due to their high efficiency and stability under diverse process conditions.

Rickman defoamers are specifically engineered for pulp and paper applications, including wastewater treatment. Our formulations offer fast foam knockdown, long-lasting suppression, and excellent dispersion in aqueous systems. These defoamers help maintain flow rates, protect equipment, and ensure consistent compliance with environmental discharge standards. Moreover, they are designed to reduce the total chemical oxygen demand (COD) contributed by defoaming agents—supporting greener operations.

What sets Rickman apart is not only our advanced product portfolio but also our application-driven service model. We collaborate closely with customers to understand site-specific challenges and provide customized solutions backed by technical support, rapid sampling, and on-site testing. Whether it's a high-load biological treatment plant or a closed-loop recovery system, our team ensures the optimal defoaming strategy for your needs.
