The Polyester synthetic fiber (PSF) industry has recycled Polyethylene Terephthalate (PET) bottle into raw material and converted them into economically valuable textile materials. This study was aimed to provide an overview of wastewater treatment from PSF industry in minimizing its impact on the environment. The study of wastewater treatment from PSF industry has been carried out in chemical-physical treatment. The Jar Test experiment has been conducted with coagulant and flocculant addition into 1,000 mL of wastewater inside a 1 L beaker glass. Wastewater was treated with 3 coagulants and flocculant doses variation with range of PAC 175-225 mg/L and PE 0.25 mg / L. The results showed that the dose utilization of 200 mg/L of 5% Poly Aluminum Chloride (PAC) coagulant solution and 0.25 mg/L dose of 0.02% Poly Electrolyte (PE) flocculant solution could produce a treated wastewater that has complied with the effluent quality standards. The application of this optimum dose can reduce wastewater pollutants subtances of PSF industry which can minimize its impact on the environment.
