Abstract
PURPOSE: To recover oil contents with high accuracy without overloading a membrane separator by roughly separating degreasing liquid to floating oil and emulsions by gravity and separating these by using membranes meeting their respective characteristics.
CONSTITUTION: The degreasing liquid in a degreasing tank 1 to be circulated and reutilized by a pump 1a is fed into a storage tank 5 where it is separated to at least floating oil and emulsions. A cylindrical weir plate 5a of a small diameter is inserted into the tank 5. The floating oil is sucked with a pump 10 from the inside of the wier plate and is fed into a coarse graining and separating filter 7 whereit is subjected to oil-water sepn. The oil is recovered from an arrow A. On the other hand, the emulsion are removed from the outside of the weir plate and is forcibly fed into an ultrafilter 6 by means of a pump 9. The liquid C permeated through the membrane is returned together with the clean water B from the filter 7 into the tank 1. A part of the concd. liquid is fed to the tank 5 and the rest to the filter 7 where it is separated of oil and water. According to this method, the oil of high purity is recovered and the treated liquid of high cleanliness is reutilizable.
