treatment techniques
• Physico-chemical properties of the pollutant in the final effluent
• Nature of the generated solid wastes from the treated water
• Economic feasibility
• Environmental fate and handling
• Running cost (Lakshmana Prabu et al. 2016).
2.1 Physical and Chemical Effluent Treatment Techniques
Different methods are performed for the dye-contaminated wastewater treatment, the
treatment techniques are (Ahmad et al. 2015).
• Coagulation/Flocculation
• Membrane separation
• Ion exchange
• Advanced oxidation process
• Adsorption by activated carbon
• Fenton’s reagent
• Ozonation
• Photochemical
• Electrochemical destruction
• Irradiation
• Electro kinetic coagulation.
2.2 Coagulation/Flocculation
Coagulation/Flocculation is a physico-chemical process that assists the accumulation
of fine particles (colloids) contained in water to form a floc that can be easily removed
through filtration water.
Coagulation—Aggregation with specific type where the aggregates are compact in
nature.
