    2019-01-20· 1. Introduction. In the textile industry, water consumption varies greatly according to different sectors, such as the colouring process, which may need more than 100 L kg −1 of processed fabric. Besides the consumption, another determining factor is the composition of the wastewater in relation to the seasonality that can widely differ from one industry to another (Vajnhandl and Valh, 2014).

    Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration) to enhance the ability of a treatment process to remove particles. Coagulation is a process used to neutralise charges and form a gelatinous mass to trap (or bridge) particles thus forming a mass large enough to settle or be trapped in the filter.
