chlorine dioxide gas Articles

  • Chlorine

    Due to the complexity of chlorine chemistry, the activity and forms of chlorine is not well understood. Its reactions are not always 'predictable' and are somewhat unique. This memo is intended to provide some simple insight of the most common forms of chlorine that we at Osmonics® encounter. The most basic form of chlorine is Chlorine Gas (Cl2). This is usually the cheapest form of chlorination, ...

  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • From Gas to Liquid: Large-Scale Chlorination System Conversion

    Abstract A number of wastewater treatment facilities using gas disinfection have decided to convert to liquid disinfection for several reasons including safety, regulatory, security, and economic factors. An optimal technology plan should be developed to facilitate the conversion. This presentation provides a case study of a large chlorine disinfection system, and demonstrates key issues of ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Gas Safety in Confined Spaces

    Introduction A confined space is any space large enough for someone to enter and perform assigned work, which has limited means of entry or exit, and which is not designed for continuous worker occupancy. This covers just about every industry, including utilities, construction, hydrocarbon exploration and processing, petrochemicals, marine, agriculture, food processing and brewing, as ...

  • Utilisation of landfill gas for the generation of energy

    The gases in landfill sites that develop during degradation processes, largely contribute to the greenhouse effect and additionally harbour considerable safety and health hazards. However, they are also often rich in methane and therefore a potential energy carrier. In many countries much of this potential for the generation of electricity and heat from landfill gas still exists. Furthermore, ...

  • A Four Channel Gas Detector for Wastewater Treatment Plants

    Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...

  • Indoor Air Quality and Hazardous Gas Detection

    Indoor air contaminants come in a variety of forms and originate from multiple sources. Interactions between building materials and furnishings, activities and equipment inside the building, internal temperature and relative humidity, filtration and ventilation system operations, climate and building occupants all contribute to the indoor air quality (IAQ) in commercial, industrial, residential ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • EPA plans to make greenhouse gas (GHG) emissions reporting mandatory

    Mandatory carbon (CO2) emissions reporting is more important than ever as the United States works with facilities to reduce substances known to adversely affect air quality, the climate, and lead to global warming. Most of the known matter that is destroying the earth’s ozone layer and contributing to global warming is derived from manmade compounds and chemicals with high global warming ...

  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Blue-White's Flex-Flo A3 Peristaltic pumps in sodium hypochlorite applications

    The use of peristaltic pumps as the most effective method to pump sodium hypochlorite in water treatment plant applications.   Tube life averages 7000-7500 hours in this low pressure application illustrated below: The quality of life for Americans was greatly enhanced in the early 1900’s due to the introduction of chlorinated drinking water throughout the United States water ...


  • Wastewater Disinfection Technology Evaluation: From the Public Health and Security Perspectives

    This paper will compare alternative wastewater disinfection technologies based on the security vulnerability and the production of disinfection by-products while considering the effectiveness, reliability and cost of each technology. Increasing public attention and tighter regulation on DBPs, along with perception of security vulnerability on the existing chlorination systems, require more ...

  • Cooling tower legionella pneumophila study CDC

    Abstract Since the late 1970s, there have been many small and large outbreaks of Legionnaires’ disease. Most of these outbreaks have been traced to either cooling tower water systems or potable water systems. Although the bacteria most often associated with Legionnair’s disease, Legionella pneumophila, is present in many waater systems, outbreaks are usually a result of ...

  • Treament of Hydrogen Sulfide (H2s)

    This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...
