Response Surface Analysis of density and flash point in recycled Waste Cooking Oils

Multivariate Surface Responding Analysis (SRA) was employed for optimize the water treatment procedure of Waste Cooking Oils (WCOs) in terms of density and flash point temperature. The simultaneously effect of pH, oil/water ratio, temperature, time and of their combinations on the process outcome were elucidated and exploited for enhance the quality of the recycled oil and the sustainability of the overall treatment.
