Abstract

PURPOSE: To float floc in raw water efficiently by directly dissolving air into raw water under pressure and then returning the pressure to normal level to create bubble in the raw water.
CONSTITUTION: In an equipment for floc removal in water, floc-containing water to be treated is reserved in an airtight tank 10, and aerial gas is aerated through an aeration plate 21 under high pressure and is dissolved into raw water to be treated. A valve 17 is opened to reduce the pressure to normal level to create fine bubbles. By these fine bubble, floc in water to be treated is floated and after the floated floc in collected and removed through valve 16, treated water in the airtight tank 10 is discharged through a valve 12. Thus, when floc-containing water to be treated is put into airtight tank through a valve 11 and when it is breated by adhering bubble to floc for flotation, folc is prevented from breaking and besides, becuse bubble are, formed around floc as cores, it provides efficient adhesion and high removal rate
