The objective of this study was to investigate the potential for reducing freshwater consumption through recycling, low cost wastewater treatment and beneficial use of sludge of beverage industry at Hattar industrial estate (HIE), Haripur, Pakistan, under the concept of clean technology and water recycling. Samples were collected from end of pipe and analyzed for various physico-chemical parameters such as flow rate, temperature, conductivity, odor, chloride, sulfate, sodium and calcium which were found below the National Environmental Quality Standards (NEQs), while pH, color, turbidity, alkalinity, hardness, total dissolved solids (TDS), total suspended solids (TSS) and chemical oxygen demand (COD) were found above the NEQs level. The treatment techniques comprised of sedimentation, coagulation and adsorption, were designed for those parameters which were beyond the Pak-NEQs. The optimum doses of coagulants were 15, 25, 35, 45 and 55 ml/l with 5:1 ml alkalinity were identified and removed significant amount of pollution loads. After treatment, the achieved sludge was processed for identification of organic and inorganic contents in terms of their beneficial purposes. The treated water was used for Agriculture, municipal and in industry such as washing of carats, bottles and floor, cooling and other minor activities within the premises of industry.
