II. INTERNATIONAL ISTANBUL CONGRESS (2.ULUSLARARASI İSTANBUL MULTİDİSİPLİNER BİLİMSEL ARAŞTIRMALAR KONGRESİ), İstanbul, Turkey, 28 - 29 September 2022, pp.617-624
With the increase in the human population, the need for energy and the consumption society, the amount of waste produced is increasing day by day. Gravity treatment method, which is one of the wastewater treatment methods, was used in this study. Within the scope of the related method, the effect of wastewater treatment capacity was investigated by using a treatment system consisting of composite plates. In the designed system, the effects of the pumping speed of the wastewater to the treatment system, the distance between the plates, the length of the plates and the radius of the holes on the plate surface on the treatment capacity were observed. Optimization has been made in order to determine the effect of each parameter on the treatment capacity in a healthy way and to determine the optimum experimental design in which the maximum treatment capacity can be obtained. Pumping speed of wastewater to the treatment system (0.01, 0.04, 0.06 m/s), distance between plates (15, 25, 35 mm), lengths of plates (600, 800, 1000 mm) and radius of holes (20, 40, 60) on the plate surface mm) parameters were taken into account and the optimization process was carried out using the Response Surface Method (RSM). In the optimization process, each experiment was performed in duplicate in accordance with the experimental plan created in line with the Box-Behnken design. According to the results of the experiment and the optimization model obtained, the degree of effect of the parameters on the treatment capacity was determined. In addition, the treatment capacity equation, which depends on all parameters, has been obtained and the verification process of the related equation has been carried out. As a result of the study, it was seen that each parameter taken into consideration affects the treatment capacity. The experimental design in which the maximum treatment capacity can be achieved was obtained when the pumping speed of the wastewater to the treatment system was 0.045 m/s, the distance between the plates was 28 mm, the length of the plates was 795 mm and the radius of the holes on the plate surface was 46 mm, and the necessary verification was carried out. In addition, the most effective parameter in the treatment capacity was determined as the plate radius of hole.
