In the pulp and paper industry, wastewater treatment is a critical step not only for environmental compliance but also for maintaining smooth and efficient plant operations. During the treatment of effluent streams rich in surfactants, lignin derivatives, and biological materials, excessive foam often forms—leading to issues such as overflow, reduced treatment efficiency, equipment damage, and regulatory challenges.

Foam formation in aeration tanks, clarifiers, and flotation units can hinder oxygen transfer and microbial activity, ultimately compromising the performance of biological treatment systems. To mitigate these challenges, high-performance defoamers are essential. These specialized additives help rapidly collapse and prevent foam formation, ensuring stable operation across various stages of the water treatment process.

Rickman defoamers are designed with the unique demands of pulp and paper wastewater in mind. Our formulations offer excellent dispersibility, fast foam knockdown, and long-lasting control—especially in high-pH, high-temperature, and high-solids environments typical of this industry. Whether applied in primary treatment, DAF systems, or secondary biological processes, Rickman defoamers deliver consistent and reliable results.

What sets Rickman apart is not only the quality of our products but the depth of our customer support. We work closely with paper mills and water treatment operators to tailor solutions based on system analysis and application needs. With in-house technical support, on-site guidance, and responsive service, we help clients maximize operational efficiency while meeting sustainability goals.
