Jan 01 2015 The following aspects have been evidenced in the integrated process studied wastewater nature i.e. dispersed and dissolved oil in the produced water the addition of the surfactant agent at a limited concentration and the use of air in the flotation stage which promotes the photochemical degradation as a polishing role.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing paper recycling and waste-water treatment industries. Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century.
Mar 15 2016 Offshore produced water contains various organic and inorganic substances from geologic formations. Stephenson 1992b categorized produced water constituents into oil organic compounds salt dissolved oxygen heavy metals radionuclides and treatment chemicals. Other contaminants such as production solids and dissolved gases are also present Fakhrul-Razi et al.

Produced water consist of oil content dissolve solid and suspended solids. This research interested on treated produced water results from Iraqi midland oil company from suspended solid contamination and oil content. The production rate of produced oil and produced water at 2015 were 140103bbld and 27.56103 bbld respectively. While the .
A combined sedimentation and pressure floatation wastewater treatment tank includes a tank body a sedimentation treatment device and a pressure floatation treatment device. The tank body contains a predetermined amount of wastewater for treatment. The sedimentation treatment device is operated to remove relatively heavier sludge from the wastewater by sedimentation treatment and the pressure .
