Abstract: Methods and systems of treating textile wastewater may involve reducing the pH of the wastewater to a threshold pH range prior to adding a transition metal source and oxidizing agent to the wastewater for reducing total suspended solids (TSS), biochemical oxygen demand (BOD), and chemical oxygen demand (COD). The system design allows for optimum residence time for the chemistry to interact with wastewater effluent and remove unwanted precipitates within the wastewater source. Beneficially, the methods and systems can remove precipitates in a continuous system without the need for filtration systems.
