Abstract: This study aims to investigate the feasibility of using a flotation unit as the primary treatment process for municipal wastewater treatment and utilize the treated water for irrigation. A metal salt namely polymerized aluminum chloride (PAXXL 36) and two flocculation chemicals namely: a high molecular weight polymer (HM) (SNF Nordfloc C-192) and a low molecular weight polymer (LM) (Purfix 120) were used as the flocculating agents. Apart from the chemicals needed for flock formation, the DAF (Dissolved Air Flotation) unit was used, which supplies compressed air essential for the flock flotation. Laboratory experiments were carried out to analyze COD (chemical oxygen demand), ammonium, nitrate, total nitrogen and phosphorus using Dr. Lange cuvettes. The minor changes in the design unit gave better results and expected water quality, which can be utilized for irrigation purpose was achieved. A significant and consistent reduction in the amounts of phosphorus and COD were observed. High dosages of metal salt and polymer were observed to yield better results but this is an unsustainable, non-eco-friendly and also expensive practice.
