Application of ozonation in drinking water disinfection based on an environmental management strategy approach using swot method

Disinfection is the destruction of pathogenic microorganisms. It does not apply to nonpathogenic microorganisms or to pathogens that might be in the spore state (McCarthy and Smith, 1974). Chlorine is the most widely used disinfectant because it is effective at low concentration, is cheap and forms a residual if applied in sufficient dosage. It may be applied as a gas or as a hypochlorite, the ...

A comparison of the Eulerian and particle tracking approaches for prediction of ozone contactor performance

The Eulerian and particle tracking approaches, two commonly utilized numerical methods, were evaluated for modelling drinking water ozone disinfection systems. The Eulerian approach predicts disinfection performance by solving an advection-diffusion equation. Alternatively, the particle tracking (Lagrangian) approach calculates disinfection efficiency by numerically introducing particles into the ...

Improving the biological stability of drinking water by ion exchange

To guarantee a good water quality at the consumer’s tap, natural organic matter (NOM) should be (partly) removed during drinking water treatment. The objective of this research is to measure the effect of NOM removal by ion exchange on the biological stability of drinking water. Experiments were performed in two lanes of the pilot plant of Weesperkarspel in the Netherlands. The lanes consisted of ...

Using Ozone Disinfection for EDC Removal

Clark County Water Reclamation District (CCWRD) serves the suburban area in and around the city of Las Vegas. The Las Vegas Valley is served by three treatment plants, which all discharge to the Las Vegas Wash. The wash empties into the Las Vegas Bay of Lake Mead. Lake Mead is also the source of drinking water for the Las Vegas Valley. In 1996 USGS reported symptoms of estrogen exposure in carp ...
