Separation process and apparatus
Abstract
Abstract THE TREATMENT SYSTEM OF THIS INVENTION INCLUDES A PROCESS AND APPARATUS FOR SEQUENTIALLY SUBJECTING PARTICULATE MATTER IN A LIQUID MEDIUM TO COMMINUTION, AERATION, FLOTATION AND DIGESTION OR INCINERATION. AERATION PREPARES THE PARTICULATE MATTER SO THAT THE INFLUENT TO A FLOTATION CELL IS OF A PROPER SIZE AND CONSISTENCY FOR MAXIMUM SEPARATION AND MINIMUM DETENTION UNDER THE ACTION OF MINUTE GAS BUBBLES OF THE SIZE PRODUCED BY ELECTROYLSIS IN THE FLOTATION CELL. THE SOLID PARTICLES WHICH ARE THEREBY CARRIED TO THE SURFACE OF THE FLOTATION CELL ARE PERIODICALLY OVERFLOWED INTO A DIGESTER OR INCINERATOR BY CLOSING THE PLANT EFFLUENT LINE WHICH CARRIES THE CLEARIFIED LIQUID FROM THE PLANT. A MODULAR DESIGN IS UTILIZED TO ALLOW FOR EXPANDING SYSTEM''S REQUIREMENTS.
