Abstract
PURPOSE:To exactly detect precipitation and sepn. and to recover a supernatant liquid having high purity by providing electrostatic capacity electrodes and arithmetic control part, etc. CONSTITUTION:The electrodes 1 are exposed in the air in the state in which a waste liquid 7 of a storage tank 2 is below a supernatant taking out nozzle 3 and, therefore, the specific dielectric constant calculated by the arithmetic control part 5 is equiv. to 1.0 value in the air. Whereas, the turbid waste liquid 7 comes to exist between the electrodes 1 as well when the liquid 7 is transferred into the storage tank 2 and is filled therein above the nozzle 3. Then, the specific dielectric constant calculated by the control part 5 attains the value of the mixed body consisting of the waste resin included in the water. The specific dielectric constant calculated by the control part 5 changes as well if the waste resin particles existing between the electrodes 1 settle upon lapse of time and the water gradually attains the clear state. The specific dielectric constant is approximated to the specific dielectric constant of the water when the supernatant liquid attains the state of the clear water. Output 6 is emitted when the purity of the supernatant liquid is maximized. The supernatant liquid of the high purity is thus recovered.
