Abstract:

In this study, the chemical pre-treatment of particle board waste water by coagulation/flocculation method was investigated. The parameters and levels used in the study were designed using the Response Surface Method (RSM), and the model equations were derived by optimizing the results. In the scope of the study; Flo30 was used as coagulant and anionic potato starch (APN, 1%) was used as flocculant. As independent variables; initial pH (5-8), Flo30 coagulant dose (6-12 ml/L), APN dose (10-30 ml/L); Chemical oxygen demand (COD,%), total suspended solids (TSS,%) and color removal efficiencies (%) were chosen as dependent variables. The conditions that maximize the removal of each dependent variable were determined separately and validation experiments were carried out under these conditions. Under maximum removal conditions, the COD, TSS and color removal efficiencies are respectively; It was found as 56.83%, 96.46%, 83.2%. The R2 values of the models obtained were 0.9501, 0.9666 and 0.9377, respectively. It has been determined that chemical treatment is an effective method in the pre-treatment of particleboard wastewater.
