Abstract
A method of removing silicone oils from waste water generated by a silicones manufacturing plant including the step of centrifuging the waste water to concentrate silicone oil contaminated solids while removing the silicone oils. The silicone oil contaminated solids are then dried in a continuously mixed sludge dryer to remove more silicone oils from the sludge to form a sludge product which comprises at least 10% water and a low silicone oil concentration.
