  • On-Site Chlorine Generation Feasibility Study

     ABSTRACT Gaseous chlorine has been effectively used for disinfection in drinking water and wastewater treatment for decades. While various regulatory programs have placed numerous restrictions on the uses of this chemical due to its hazardous nature, recent focus on the possibility of a terrorist attack at a drinking water or wastewater facility, has underscored the potential hazard ...

  • Dangers of Chlorine

    Most of us have grown up with the idea that whiter whites (and brighter colors) mean cleaner clothes. We continue to use chlorine products with abandon to whiten and to disinfect. We write on white paper and bathe in and drink chlorinated water. After all, who wants bacteria-infested water? In our society, chlorine is ubiquitous-and so are its side effects. In fact, the long-term residual effects ...

  • Chlorinated hydrocarbons - Case Study

    Example: Pharmaceutical industry Similar tasks: Chemical industry The Pharmaceutical industry uses different processes to create chlorinated hydrocarbons. In a regenerative thermal oxidiser (RTO) the chlorinated organic contaminants are destroyed at high temperature. Chlorinated hydrocarbons - among others - are converted into hydrogen chloride which produces a ...

  • Controoling chlorine costs

    The most widespread disinfectant used in the treatment of drinking water is chlorine, which can be applied in a variety of ways. History has taught us that, in bacteriological terms, chlorinating water is a proven way of disinfecting drinking water. After all, more than 75 years have passed since chlorine was used to disinfect drinking water for the first time. Many years of experience have shown ...

  • Factors Affecting Cyanide Generation in Chlorinated Wastewater Effluent Matrix

    ABSTRACTFalse positives for cyanide analysis in wastewaters have been reported. We examined the effects of storage time at high pH and of pH adjustments on the cyanide levels. Cyanide levels changed within the holding time allowed by Standard Methods. We also studied the difference in cyanide levels using two disinfection conditions -- breakpoint chlorination and chloramination. Glycine was used ...

  • Controlling the addition of Chlorine into a Process

    There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...

  • A general framework of chlorine decay modeling at a pilot-scale water distribution system

    Understanding the variation of chlorine concentrations in water distribution systems is important for determining the schedule of rechlorination. Maintaining an appropriate chlorine concentration in domestic tap water and a sustainable residual chlorine in water distribution systems is an important commitment to ensure high drinking water quality. A generic modeling framework is proposed to ...

  • Sanitation Using Ozone & Chlorine

    For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature’s strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium. It also has some unpleasant byproducts. Together, however, these two substances can ...

  • Pulse-Chlorination®, the Best Available Technique in Macrofouling Mitigation Using Chlorine

    In 1998, KEMA developed a new chlorination method called Pulse-Chlorination®. It enables optimal antifouling treatment with a minimum use of chlorine. This technology is based on the principle that in general mussels and clams have a re-covery period after exposure to chlorination before opening fully and restarting filtration. The method takes advantage of this recovery time by using short ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • Response of mussel Brachidontes variabilis to chlorination

    Untitled Document Brachidontes variabilis is a common fouling mussel species in cooling water systems of tropical coastal power stations. However, there are hardly any data available ...

  • Simplifying Cyanide Treatment Through In Situ Electrolytic Chlorine Generation/Regeneration: Not So Simple

    This paper presents results of testing in situ generation/regeneration of chlorine from chloride at less than stoichiometric concentrations required for oxidation of cyanide. The goals were to provide effective oxidation and minimizing residual total dissolved solids (TDS) addition. Cyanide wastewaters produced in the plating operations are typically treated by conventional caustic chlorination ...

  • Chemistry of Chlorine Application and Production for the Disinfection of Water and Wastewater

     ABSTRACT A thorough understanding of chlorine and sodium hypochlorite chemistry is essential in optimizing their usage in disinfection of water and wastewater. High price of both chemicals and hazards involved in their transportation to plant sites have prompted many utilities to consider generation of these chemical on-site. A detailed discussion of the critical engineering concepts ...

  • Key Operating Strategies for Chlorine Disinfection Operating Systems

    ABSTRACTChlorine has been used as a standard for disinfecting wastewater for many years. While being the standard There are many levels of automation for control of disinfection. To select the best control approach for your facility both control strategies and chlorination chemistry must be understood. Permit conditions must also be fully identified; organism concentrations and operational data. ...

  • 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 ...
