How can a cooling tower spread Legionnaires' Disease?
It really should be one of the happiest, most carefree destinations on the planet; however perennial family favourite, Disneyland, found itself at the epicentre of an outbreak of Legionnaire’s disease just before Christmas, as you might have read elsewhere. As well as being an obvious PR disaster for the globally-renown resort behemoth, any possible risk presented by the presence of the potentially deadly respiratory infection could spell more far-reaching bad news for those directly affected by an episode.
Calculos Basicos para Torres de Enfriamiento
Teóricamente, la evaporación de una torre de refrigeración es agua pura. Todos los iones disueltos se quedan atrás a concentrarse en el sistema. Si la única pérdida de agua del sistema fue a través de la evaporación, los iones disueltos en el agua de recirculación seguirían concentrarse (de los iones después de la evaporación) hasta que la solubilidad de cada ion en el agua fue superado y masiva escala / deposición dio como resultado.
Cooling Tower Basic Calculations
The recirculation rate and the temperature drop across the cooling tower are the two pieces of data needed to calculate the amount of water lost from the open recirculating cooling system (due to evaporation). Following items will be discussed and calculated in this article : - Evaporation - Temperature Drop - Recircul
Chlorine Dioxide for Effective Water Treatment
In conclusion, recent studies have confirmed that chlorine dioxide is an effective alternative oxidizing program to sodium hypochlorite and chlorine gas for treatment of industrial cooling water systems. Industrial plants using raw or recycled water, experiencing process leaks, facing AOX/THM discharge violations, not meeting their microbial control goals or operating cooling towers at pHs higher than 7.5 should consider the use of chlorine dioxide.
