Textile wastewater treatment system

Textile and dyeing industries are one the largest consumers in the world, so they produce huge amount of wastewater and this wastewater have wide range of pollutants such as pigments and auxillary materials like dispersants, homogenizers, carriers, salts, acids, alkalis, and sometimes heavy metals. Similar to most industrial waste treatment packages, there are two main steps in textile and dyeing waste treatment. chemical and physical treatment and then biological treatment (biofilter). In the physical and chemical phase of purification the first step is adjusting the pH in neutral range, and then due to the high turbidity the chemical coagulation method is used to remove the pigments and suspended particles. In the last step an aerobic biofilter stage is used to remove the remaining materials. The image of a textile wastewater treatment system with a capacity of 100 cubic meters per day is shown below.
