Vegetable Oil Refinery Wastewater Treatment by Using the Cactus as a Bio-flocculant in the Coagulation-Flocculation Process

Industrial wastewater has a considerable environmental impact on the environment. Wastewater from oil refining, which has been removed from oils, grease, detergents, and phenol, is one of the effluents which present a particular danger to the environment. In this study, we used bio-coagulants to reduce pollution by coagulation-flocculation of wastewater from oil refining. This study shows an ...

chemical refining and physical refining of vegetable oil

Chemical Refining and Physical Refining of Vegetable Oil

Physical refining means the removal of gum from oil via the process of degumming, a special method for removing FFA in the process of deodorization by steam. Chemical refining, however, means chemically removing FFA (acid-base neutralization). Gum and soap produced in the last step are then separated by centrifuge.
