| Resumo: | The aim of this work is to examine the performance of a glass column filled with a sand filter in oil removal from oilfield produced water (OPW) and synthetic produced water (SOPW). This paper investigated the influence of process parameters such as physical characteristics of sand, column height, types of effluent (oilfield produced water and synthetic produced water), and oil concentration on oil removal efficiency. An OPW sample was taken from effluents of the oilfield unity located at Rio Grande do Norte State (Brazil), and the SOPW sample was prepared using two types of oils and salts (NaCl and KCl). The results showed that the oil concentration decreased significantly after the filtration process. The oil removal efficiency was influenced by the sand particle size and bed height, reaching 90% using a 30 cm high sand bed composed by mixed grain sizes |
