APPARATUS FOR REMOVAL OF SOLID, CHEMICAL AND BACTERIAL WASTE FROM WATER

摘要

A process and system for purifying water containing solid, chemical, and/or bacterial wastes is described. Contaminated water is introduced (25) to a pre-charged chamber (30) defining a solid clarifier stage in which the water is bombarded with gaseous oxidant (I) to cause flocculation of the solid contaminants. The flocculated solids are removed, and the water is saturated with gaseous oxidant and passed into a fluid body (38) at ambient atmospheric pressure so as to cause the gaseous oxidant in the water to expand and thoroughly mix with the fluids, destroying bacterial and chemical contaminants. A portion of the resulting mix fluid is withdrawn (77), subjected to UV radiation (82), and degassed (85). The remainder, between 30 % and 37 % of the total volume of contaminated fluid introduced to the tower, is recirculated (75, 76) back to the solid clarifier stage (30) and processed again.
