| 摘要： | Objectives: To; (1) assess biological stability and disinfection by-product levels in New York City drinking water, (2) develop correlations between biological stability of drinking water and routinely measured water-quality parameters, (3) evaluate and optimize chlorination practices with respect to biological stability, (4) evaluate various water-treatment unit processes for producing biologically stable water, and (5) determine the energy and other costs of water treatment and disinfection when producing a biologically stable finished water. R&D Results: The study found that New York City water remains relatively stable in the distribution system. If treated with ozone at CT values greater than 0.5 mg-min/1, previously chlorinated water from the Croton system yields levels of organic carbon that could lead to significant biological activity. Diatomaceous earth filtration following ozone treatment did not reduce the biological regrowth potential to pre-ozonation levels. |
