Abstract
The present invention provides for a novel method of removing emulsified oils, dissolved solids and particulates from a water containing liquid wastestream comprising chemically treating the wastestream with an acid, a coagulant, and a flocculant and subsequently flowing such treated wastestream upwardly through a vertical plate pack chamber.
Claims10
A method of removing emulsified oils, dissolved solids and particulates from a water containing liquid wastestream comprising the steps of:
- a. adjusting the pH of the wastestream to a pH of about 6;
- b. adding a coagulant to precipitate the dissolved solids;
- c. further adjusting the pH of the wastestream to a pH of about 6, whereby the coagulant and dissolved solids separate from the liquid phase;
- d. adding a flocculant to the wastestream;
- and
- e. flowing the waste stream upward through a vertical plate pack chamber aligned at an angle to the horizontal ranging from about fifty to about sixty degrees whereby the oils and solids substantially settle to the bottom of the chamber and the wastestream, separated from such oils and solids, exits the chamber from the top, wherein said chamber further comprises a tuning fork sensor capable of producing a signal indicating the amount of solids in the bottom of said chamber by changes in the frequency of vibration of the sensor, said signal activating a pump to remove said oils and solids from said chamber.
