Providing optimal methods for water treatment and waste water containing sulfur color

Sulfur dyes are inexpensive and mainly used for coloring cellulosic textile materials or mixtures of cellulosic fibers. Sodium sulfite is relatively inexpensive and considered as traditional reducing agents and used for sulfur dyes and dyeing, But touch it, is toxic and dangerous.Using it may be Leave harmful residues on fabrics completed and and produces wastewater which it's treatment is difficult and damage to the environment. Textile industries are met with high cost of water and wastewater treatment, as well as stringent environmental regulations. In this study, a variety of methods, including methods of physical, chemical and biological treatment of industrial wastewater containing paint application of sulfur was investigated This study concludes with recommendations for additional measures to improve treatment processes that can be done from both a technical and economic point of view.
