Abstract
PURPOSE:To supply sterilized water almost containing no free chlorine, by injecting ammonia and chlorine in the raw water of a water treatment plant to generate combined chlorine and controlling the injection rate of ammonia and chlorine. CONSTITUTION:The chlorine demand quantity and intake flow amount 5 of raw water are measured and the concn. of ammonia is measured by an ammonia meter 10. The raw water flowing in a water arrival basin 1 is guided to a quick mixing basin 2 and ammonium hydroxide is injected in the raw water on the way to be mixed with the raw water. Next, this raw water is guided to the quick mixing basin 2 to inject chlorine and a flocculant in said raw water. Chlorine is used in the sterilization of bacteria or the oxidation of a metal ion and the flocculant flocculates the turbid substance in the raw water into flocs which are, in turn, sedimented and removed in a sedimentation basin 3. The supernatant water becoming clear in the sedimentation basin 3 is guided to a water distribution basin 4 to be stored therein and, on the outlet side of the water distribution basin 4, residual chlorine is measured by a total residual chlorine meter 14 and a free residual chlorine meter 15 to distribute water to a user.
