Abstract :This study was carried out in two stages; in the first stage of the study, wastewater characterization of wastewater originating from the pistachio industry was primarily completed, and in the second stage, chemical pre-treatment studies were completed. 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 insert ignore into journalissuearticles values(SO 4 ); 3 , Fe 2 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(SS); removal efficiency, 65.8% chemical oxygen demand insert ignore into journalissuearticles values(COD); removal efficiency and 85.5% total phenol insert ignore into journalissuearticles values(TP); removal efficiency were obtained.
