Separation of silicone oil droplets dispersed in activated sludge
Résumé
A process in three steps involving a gas-liquid contactor with an organic phase, a TPPB and a liquid/liquid separator to recover the organic phase for its recycling was proposed to treat hydrophobic Volatile Organic Compounds. Among the processes tested for liquid/liquid separation (settling, hydrocyclone and centrifugation), the latter appeared to be the most efficient. The centrifugal acceleration needed for the separation of oil and water was found to be dependent on the viscosity of the oil used and the presence of microorganisms. The force required for phases' separation was found to be reduced in the presence of selected commercial demulsifiers.
