Eliminate operator's errors in your Chlorine residual analysis
The original development of the ChloroSense demonstrates clearly the improvement in the repeteability of Chlorine measurements in the field by completely removing any aspect of technique from the analytical procedure.
Choose the Right Cooling Tower Chemicals
Microbiocides generally belong to one of two groups: oxidizers and non-oxidizers. The former attack cells by oxidizing (an electron transfer reaction) microorganism cell components. Non-oxidizers react with cell components via different chemical processes. Oxidizing biocides are still the most common biological control agents, and even though chlorine use is declining, it continues to be an important player in the cooling water treatment industry.
Controlling Chloramination in drinking water applications
The ChloroSense results show that breakthrough is not an issue with the chemistry used on the sensor. Free chlorine residuals are monitored as below 0.05mg/l over the 2 days testing period. The total chlorine results show ChloroSense matches on the on line analyser.
Langelier Saturation Index
he Langelier Saturation Index (LI), a measure of a solution’s ability to dissolve
or deposit calcium carbonate, is often used as an indicator of the corrosivity of
water. The index is not related directly to corrosion, but is related to the
deposition of a calcium carbonate film or scale; this covering can insulate pipes,
boilers, and other components of a system from contact with water.
Cooling Towers: Efficiency Waiting to Happen
Cooling towers serve the vital role of cooling water for power plant heat exchange equipment. Sustaining excellent system performance is important because a one-degree increase in water temperature can cause a 2% increase in energy usage. Proper maintenance and a few upgrades could improve a cooling tower’s efficiency, while also saving water in the process.
Los métodos para determinar el dióxido de cloro y su oxiclorados en agua
El análisis de dióxido de cloro y su oxiclorados que adhiriéndose por los productos en agua es un tema difícil debido a la volatilidad del dióxido de cloro y a las interferencias de otras especies con métodos de prueba estándar. En las muestras reales, esto se complica aún más ya que el dióxido de cloro se utiliza a menudo en un sistema que es dinámico y por lo tanto de muestreo también es importante.
Methods for determining chlorine dioxide and its oxychlorine by-products in water
The analysis of chlorine dioxide and its oxychlorine by products in water is a difficult topic due to the volatility of chlorine dioxide and to the interferences from other species with standard test methods. In the real samples, this is further complicated as chlorine dioxide is often used in a system which is dynamic and therefore sampling is also important.
Como puede distribuir una torre de enfriamiento, la Enfermedad del Legionario?
En realidad debería ser uno de los más felices, más destinos sin preocupaciones en el planeta; Sin embargo perenne favorito de la familia, Disneyland, se encontró en el epicentro de un brote de la enfermedad del legionario justo antes de Navidad,como se podría haber leído en otro lugar. Además de ser un desastre de relaciones públicas obvia para el gigante complejo a nivel mundial de renombre, cualquier posible riesgo presentado por la presencia de la infección respiratoria potencialmente mortal podría significar un mayor alcance malas noticias para los directamente afectados por un episodio. Detrás de la fachada de la diversión de los castillos de cuentos de hadas y de tamaño natural, Mickey Mouse, Disneyland (como tantos lugares de interés público) alberga una variedad de torres de
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.
La ciencia detrás de BIOPELÍCULAS y su impacto en las torres de refrigeración
Las biopelículas son generalmente sólo unos pocos micrómetros de espesor, 100 veces menor que la sección transversal de una hebra de cabello, y los gerentes de planta no están buscando activamente para ellos. Un especialista en el tratamiento del agua, sin embargo, puede inspeccionar los sistemas de refrigeración que utilizan las últimas técnicas y analizar muestras para detectar la presencia de biofilms y asesorar sobre el tratamiento apropiado.
THE SCIENCE BEHIND BIOFILMS AND THEIR IMPACT ON COOLING TOWERS
Biofilms often aren’t considered as the cause of increased electrical costs, perhaps because they are rarely detected. Biofilms are generally just a few microns thick, 100 times smaller than the cross section of a strand of hair, and plant managers are not actively looking for them. A water treatment specialist, however, can inspect cooling systems using the latest techniques and analyze samples to detect the presence of biofilms and advise on appropriate treatment.
