“…Rejection or removal efficiency of this system to decrease oil and grease was considerably high (in the range of 98-99.9 %) showing that almost all oil was removed. Physical treatment such as EPCON [36]. Applying a copolymer could absorb up to 85 % of oil in produced water [37].…”

Oil exploration waste, also called produced water, contains hazardous pollutants, such as benzene; benzene, toluene, and xylene (BTX); naphthalene, phenanthrene, and dibenzothiophene (NDP); polyaromatic hydrocarbons (PAHs); and phenol. Produced water is characterized by high chemical oxygen demand (COD) and oil content, which exceed the standard limits of regulation. In this study, the combination of ultrafiltration (UF) and ozone pre-treatment and post-treatment were applied for treatment of produced water to minimize its environmental impact. Produced water and membrane were characterized, and their ultrafiltration performance for removal of oil content, benzene, toluene, xylene, and COD. Two commercial Polyethersulfone membranes, with molecular-weight cut-off values of 10 and 20 kDa, were used. The membrane flux profile illustrated that ozone pre-treatment had higher normalized flux than UF only. Separation performance was evaluated based on flux profile and removal of COD, oil and grease content, toluene, and xylene. Significant finding was found where the combination of UF with ozone pre-treatment and post-treatment could significantly eliminate COD, oil content, toluene, and xylene. The rejection of these components was found higher than conventional process, which was in the range of 80 % to 99 %. In addition, almost oil and grease can be removed by using this combined system. Permeate quality of this system confirmed the acceptable level as water discharge.

“…Without implementing new measures, the EIF will increase to a level higher than in 2000. The oil industry is now looking into methodology for use in combination with CTour, to reduce the BTEX concentration [7,8]. When planned measures are implemented in 2006, the risk will be reduced by about 80% compared to the level in 2000 and 85% compared to the expected level in 2006 without measures.…”

“…Physical processes usually include prefiltration or centrifugation to remove suspended and colloidal solids that may plug the module or blind the membrane, and mechanical emulsion breaking based on the phenomenon of gravity (Adewumi, Erb, & Watson, 1992;Knudsen et al, 2004). The efficiency of these methods mainly depend on the size of the oil droplets as well as the difference in density between water and oil.…”
