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.

Abstract: A water recycle system may be implemented to analyze and selectively recycle wastewater generated by an industrial textile washer. In some examples, wastewater generated by the industrial textile washer undergoes various treatment processes, such as chemical treatments (e.g., addition of flocculants, chelating agents) and/or physical separation treatments (e.g., processing in a dissolved air floatation system to remove particulates). This can generate a clarified wastewater. One or more sensors can be positioned to measure characteristics of the clarified wastewater, such as the color of the clarified wastewater and corresponding tendency to stain textile articles if recycled to the washer. Based on measurements from the one or more sensors, the clarified wastewater can be recycled for reuse in the textile washer or, alternatively, discarded.
