Traditional methods for treating inorganic wastewater include physical, chemical, and biological processes. Physical methods, such as sedimentation and filtration, can remove suspended solids but may not effectively eliminate dissolved inorganic contaminants. Chemical methods, like precipitation and ion exchange, can efficiently remove heavy metals but often involve the use of hazardous chemicals and generate secondary waste that requires further treatment. Biological methods, although more environmentally friendly, are generally less effective for removing inorganic pollutants.

Plasticizers are classified into two main categories primary and secondary. Primary plasticizers, such as dioctyl phthalate (DOP) and diisononyl phthalate (DINP), are typically used in large quantities and can significantly alter the properties of the base polymer. Secondary plasticizers, on the other hand, are added in smaller amounts and serve to enhance the performance of primary plasticizers or modify specific characteristics of the material. The choice of plasticizer depends on various factors, including cost, desired properties, and regulatory considerations.
