Kemio, the best instrument for disinfection monitoring!
Repeatable, reliable results Kemio reduces complexity and subjectivity for the user, minimizing chances for error, and delivering repeatable results for any operator. Multiparameter testing platform Kemio can test for free chlorine, total chlorine, chlorine dioxide, chlorite and peracetic acid (PAA), with new sensors added to the same device. Kemio also allows for simultaneous measurement of free and total chorine.
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.
Sulfitos para el Control del Oxigeno
disipación de oxígeno y la desactivación son los métodos más comunes de control, llevados a cabo por medios mecánicos o químicos o por una combinación de los dos. Otros métodos populares de proteger el metal en una caldera son inhibidores de pasivación y de filmación. Los eliminadores químicos más comunes, de lejos, se basan en sulfitos y bisulfitos, un enfoque que puede ser muy eficaz si las presiones de calderas no son demasiado altos, y de sólidos totales se mantienen dentro de límites prescritos.
Sulfites for Oxygen Control
The sulfite/oxygen reaction is known to be inhibited by some alcohols, phenols, amines, and thiosulfate. Other contaminants or organic treatment chemical such as corrosion inhibitors, scale inhibitors, and biocides may also slow down reaction time. A slow reaction can present a problem at early phases in a system and require the use of catalysts or feeding techniques that provide maximum time for the reaction to occur. The reaction rate for sulfite appears to be the fastest of all of the scavengers, followed by erythorbic acid and DEHA. Slower rates, in general, have been reported for hydroquinone, carbohydrazide, and hydrazine.
