wastewater treatment involves a series of unit operations that aid in removal of contaminants in a sequential and systematic approach. Initially, wastewater is treated using primary treatment process such as physico-chemical methods, where suspended and floating solids are removed. The dissolved organic matter that escapes primary treatment is subjected to secondary treatment, which primarily uses biological activity to remove the pollutants. When the biological treatment process reaches a saturation level. there are smaller amounts of untreated organic matter, nutrients, etc. (Hoffmann, 1998). This untreated wastewater can be further subjected to tertiary treatment (polishing), where the residual pollutants content is reduced and make it suitable for final disposal and reuse with the goal of achieving sustainable treatment (Kennedy and Lentz, 2000). These methods should not only be used
