Pulping Water Treatment | Improving process efficiency and product quality
Trusted by the global paper industry since 2015
Solutions for pulping water treatment in papermaking
Our pulping water treatment chemicals meet every challenge in the process：
Our innovative defoamers are designed to quickly eliminate foam and optimize industrial processes. Our defoamers use advanced technology to quickly eliminate unwanted foam in water-based and oil-based systems, ensuring smooth, uninterrupted production. They are highly compatible with other additives and maintain process stability, making them ideal for paper, coatings, printing inks and water treatment applications. Environmentally friendly and low in VOCs, our defoamers help reduce downtime and improve overall product quality while meeting strict regulatory standards.
- Silicone-based: low surface tension and can quickly penetrate the foam film, destroying the stability of the foam.
- Polyether based: reduce the surface tension of the foam, making the surface of the foam film unstable, thereby promoting the collapse of the foam.
- Fatty alcohol-based: destroy the foam structure and reduce the stability of the foam through hydrophobic effects and lubricity characteristics.
Azpc® Pe-D01 is a high-efficiency polyether defoamer designed specifically for water-based paper production processes. Developed for stable, long-lasting foam suppression, this defoaming agent features excellent dispersibility, rapid foam knockdown, and strong compatibility with aqueous systems. As a non-silicone, eco-friendly defoaming solution, it is ideal for use in applications requiring minimal residue and clean performance.
Azpc® Si-D02 is a silicone defoamer for the paper industry, formulated with modified siloxanes and emulsifiers to provide quick foam elimination and long-lasting control. It performs efficiently in both aqueous and non-aqueous systems, making it a versatile solution for a wide range of industrial paper-making environments. The product contains no harmful substances and meets regulatory safety standards.
Azfc® PD40 is a highly efficient cationic organic polymer coagulant based on PolyDiallylDimethylAmmonium Chloride (PolyDADMAC), widely used in papermaking and water treatment applications. With its high cationic charge density, Azfc® PD40 quickly neutralizes negatively charged impurities in pulp systems, significantly improving fines and filler retention, enhancing drainage performance, and boosting overall paper quality. It performs effectively across a wide pH range and is especially suitable for modern high-speed paper machines that demand consistent and efficient chemical performance. Azfc® PD40 is also highly compatible with retention aids, drainage aids, and strength additives, contributing to a more stable wet-end chemistry and improved operational efficiency.
In water treatment, Azfc® PD40 serves as a primary coagulant, effectively removing suspended solids, reducing turbidity, accelerating settling, and minimizing sludge volume. The product features low viscosity, easy dilution, and convenient handling, making it ideal for continuous dosing systems. With its excellent stability and high efficiency, Azfc® PD40 has become a trusted solution for customers seeking to optimize process stability and reduce total operating costs.
