    Abstract

    Kaedah rawatan penggumpalan dan pengelompokan digunakan secara meluas dalam proses industri. Kecekapan proses penggumpalan dan pengelompokan ditentukan oleh dos penggumpal, pH, suhu, kekuatan ionik, kepekatan bahan organik, caj permukaan dan beberapa faktor lain. FeSO4 (penggumpal) tidak didokumentasikan dengan baik dalam rawatan air sisa kilang penapisan petroleum (PRW). Oleh itu, dalam kajian ini, keupayaan FeSO4 dalam rawatan PRW telah dikaji. Kecekapan penyingkiran/pengurangan warna, jumlah pepejal terampai (TSS), kekeruhan dan keperluan okisigen kimia (COD) telah dikira. Penggumpalan dan pengelompokan boleh dipantau melalui pengukuran kegerakan elektroforetik dan penentuan potensi zeta. Dalam kajian ini, interaksi antara FeSO4 dengan zarah koloid bercas negatif dalam PRW dan mekanisme yang terlibat dalam proses penggumpalan dan pengelompokan dikaji. Tingkah laku zarah PRW yang berbeza terhadap FeSO4 bergantung kepada pH dan dos FeSO4 telah ditunjukkan. Coagulation-flocculation treatment method is widely used in industrial processes. The efficiency of coagulation-flocculation process is determined by the coagulant dosage, pH, temperature, ionic strength, nature and concentration of organic matter, the surface charge and several other factors. FeSO4 (coagulant) is not well documented in the treatment of petroleum refinery wastewater (PRW). Therefore, in this research, capability of FeSO4 in the treatment of PRW was studied. The removal/reduction efficiencies for color, total suspended solids (TSS), turbidity and chemical oxygen demand (COD) were calculated. The coagulation-flocculation process can be monitored through the measurement of the electrophoretic mobility and the determination of zeta potential. In this study, the interaction between FeSO4 and the negatively charged colloidal particles in PRW and the mechanisms involved in the coagulation-flocculation process were studied. Different behaviors of PRW particles with FeSO4 depending on the pH and the dosage of the FeSO4 were demonstrated.
