Chemical Treatment in Industrial Wastewater of Polyester Synthetic Fiber Made from Recycled Polyethylene Terephthalate Bottles: Minimize Environmental Impacts

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 ۱,۰۰۰ mL of wastewater inside a ۱ L beaker glass. Wastewater was treated with ۳ coagulants and flocculant doses variation with range of PAC ۱۷۵-۲۲۵ mg/L and PE ۰.۲۵ mg / L. The results showed that the dose utilization of ۲۰۰ mg/L of ۵% Poly Aluminum Chloride (PAC) coagulant solution and ۰.۲۵ mg/L dose of ۰.۰۲% 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.
