Treatment of Textile Wastewater by Dual Coagulant from Fe(III) and Purple Okra (Abelmoschus esculentus) Waste

One of the greatest contributions to water pollution is industrial sector, especially textile, due to high consumption of water and chemical. Therefore, the textile wastewater has an extremely complex matrix and is heterogeneous due to multiplicity of hazardous chemicals, dyes, and toxic components. Due to this fact, the real textile wastewater should be treated before disposal in waterbodies. The coagulation/flocculation process is used worldwide for the treatment of various types of industrial wastewater. This chapter highlights the growing interest in the use of natural coagulants to replace coagulants that have toxicological potential for the environment and health.
