Plastic additives and compounding are essential components in the production of plastic materials, influencing their performance, appearance, and durability. As the demand for high-performance plastics grows across various industries—including automotive, construction, packaging, and consumer goods—the role of additives in enhancing the properties of base polymers has become increasingly critical.
During the primary treatment, the focus is on physically removing large solids and floating debris from the sewage. Chemical coagulants, such as aluminum sulfate or ferric chloride, are often added to this process. These coagulants cause small particles to agglomerate into larger clumps, which can then be easily separated from the wastewater by sedimentation. This stage significantly reduces the load of suspended solids, paving the way for more efficient secondary treatment.
