Textile dyeing industry is an intensive water consumer, and thus, generates high volumes of wastewaters. In general, these effluents are characterized by high organic content, low biodegradability, variable pH values, low suspended solids content and presence of color.
Generally, satisfactory results are obtained using a biological treatment followed by a tertiary refining step of decolonization by adsorption onto granular activated carbon (GAC) in a fixed-bed column
Another combination between biological methods and adsorption is the PACT (Powdered Activated Carbon Treatment), The PACT system combines simultaneously biological treatment and carbon adsorption into a single, synergistic treatment stage and has proved to be efficient in the removal of both biodegradable and non-biodegradable compounds.
