Title: TREATMENT OF SLUDGES AND FLOCCULANTS USING INSOLUBLE MAGNESIUM HYDROXIDE COLLOIDAL SUSPENSIONS
Abstract:
A method of separating sludge which involves adding an insoluble mineral colloidal suspension into an industrial sludge to destabilize the industrial sludge and separating destabilized components of the industrial sludge. The insoluble mineral colloidal suspension includes magnesium hydroxide. In an alternative embodiment dry finely divided magnesium hydroxide can be added and then dispersed into an industrial sludge. Conventional flocculants and/or coagulants can also be added. Conventional physical separation processes can be used to separate the destabilized industrial sludge.
