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.

Following the removal of solids, disinfection is typically employed to eliminate any remaining pathogens. Common disinfectants include chlorine, ozone, and ultraviolet (UV) light. Each method has its own advantages and disadvantages; for instance, while chlorine is effective and inexpensive, it can produce harmful disinfection byproducts. In contrast, UV disinfection is environmentally friendly and poses no risk of residual contaminants, but it requires careful monitoring to ensure effectiveness.
