Abstract
Dye wastewater from industries poses significant health hazards to the environment, so it is important to limit its discharge into receiving waters. This overview discusses several feasible, low-cost treatment methods, which includes biological, chemical and physical approaches. Adsorption and membrane filtration are the two common and widely acceptable physical methods, whereas chemical (or widely known as oxidative methods include Fenton treatment, ozone treatment, H2O2 UV irradiation, hydrogen peroxide, NaOCl, ion-exchange, electrocoagulation, reverse process, nanofiltration, etc.). Biodegradation can occur either aerobically or anaerobically, and both of these are examples of the biological techniques. When it comes to the treatment of wastewater effluents from the textile industry, there are primarily two areas of concern: selecting the appropriate technology and developing an appropriate treatment strategy. However, The treatment of dye solutions typically depends heavily on electrochemical processes.
