Title
Application of Bubble Water for Development of Sequential Soil Washing System

Abstract
Oil contaminants attached to soils were separated using the bubble energies from the bursting and coalescence. The separation efficiency increased when the rotary kilns were combined Wastewater containing separated oil contaminants was treated with the buoyant energy of bubbles and with positively charged bubbles. The water quality of treated wastewater was good enough for the latter to be used as recycled water for bubble generation the separation and treatment efficiencies of the novel oil washing process developed in this study was found to be similar to that of the existing oil washing process operated under high temperature and high pressure conditions and with dosage of chemicals.
Key Words
