Pistachio wastewater used in the study was obtained from a pistachio processing factory located in Gaziantep province. In chemical treatment studies, montmorillonite clay, AlCl 3 , Al 2 (SO 4 ) 3 , Fe 2 (SO 4 ) 3 and FeCl 3 were used as coagulants. As a result of chemical treatability tests, AlCl 3 was determined to be the best coagulant. With AlCl 3 at optimum dosage and optimum pH value, 99.6% suspended solid (SS) removal efficiency, 65.8% chemical oxygen demand (COD) removal efficiency and 85.5% total phenol (TP) removal efficiency were obtained. </div>}, number={4}, publisher={Mehmet Sinan Bilgili}
