Colorants, including pigments and dyes, enhance the aesthetics of plastic products. They can provide vibrant colors, improve opaqueness, and even impart special effects such as metallic or pearlescent finishes. The choice of colorant depends on the desired application and the properties of the base polymer. For example, certain pigments are designed to withstand UV light to prevent fading and maintain the product's appearance over time.

These physical methods serve as a foundation for water treatment systems, effectively reducing the turbidity and suspended solids in water, making subsequent chemical treatments more efficient.

Coagulation and flocculation are fundamental processes in water treatment used for removing suspended solids. Coagulants, such as aluminum sulfate (alum) and ferric chloride, neutralize the charges of suspended particles in water, causing them to clump together. This aggregation forms larger particles or flocs, which can then be removed more easily. Flocculants, on the other hand, are polymers that aid in forming larger flocs and enhancing sedimentation.


Moreover, chemical treatment processes can be tailored to meet specific regulatory requirements, ensuring that discharged water complies with environmental standards. This flexibility is particularly beneficial for industries that generate highly variable wastewater streams. The ability to adapt the treatment process according to specific pollutants helps in achieving consistent treatment outcomes.
