With the global increase in environmental awareness and stricter regulations, such as the EU's RoHS environmental directive, higher environmental requirements are being imposed on plastic additives. Calcium Acetylacetonate, as a RoHS-compliant eco-friendly product, is an ideal replacement for lead-based additives. This positions it as a high-performance, cost-effective new plastic stabilizer in the market. Particularly in applications involving halogenated polymers like PVC, its market potential is substantial.

Sewage treatment plants (STPs) are critical infrastructures designed to process and purify wastewater before it is released into the environment or reused. The treatment of sewage is a complex process that not only aims to eliminate harmful substances but also to protect public health and the environment. To achieve these goals, various chemicals are employed in STPs to aid in the treatment process. This article will explore the key chemicals used in sewage treatment, their functions, and their significance in ensuring effective wastewater management.

Chemical treatment is typically employed after primary physical treatment methods. It involves various processes such as coagulation, flocculation, sedimentation, and disinfection. Coagulation is the initial stage, where chemicals known as coagulants (commonly aluminum sulfate or ferric chloride) are added to wastewater. These coagulants destabilize suspended particles, allowing them to clump together, forming larger aggregates known as flocs.

Functional fillers play a crucial role in the development of high-performance plastics that meet the demands of modern applications. As industries strive for greater efficiency and sustainability, the strategic use of these fillers will become increasingly important. By enhancing the properties of plastics, functional fillers enable innovations that not only improve product performance but also contribute to environmental sustainability. The future of plastic materials lies in the continued exploration and application of functional fillers, paving the way for more advanced, resilient, and eco-friendly solutions.
