wastewater treatment for removal of dyes by coagulation

Wastewater treatment for removal of dyes by coagulation

The development of effective wastewater treatment means and processes is one of the most important problems of textile dyeing-and-finishing plants. Textile dyeing wastewater contains large amounts of chemically different synthetic dyes, surfactants, and mineral substances, which are responsible for a serious chemical load on municipal wastewater treatment facilities.
