  • 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. ...

  • Emergency equipment for the absorption of chlorine in hospitals - Case Study

    Chlorine is a strong oxidant that in normal conditions and in its pure state formsdichlorine, a toxic gas with a yellow-greenish colour formed by diatomic molecules (Cl2) that are about 2.5 times heavier than air and have an unpleasant smell. Among its multiple applications and due to its powerful oxidising nature, it is widely used forwater purificationin sewage treatment plants and as ...

  • Water reuse for the bottled water industry

    ABSTRACTThe bottled water industry uses a machine specifically designed for the washing of its containers (19-L capacity) and generates 6-L wastewater/container. This effluent can be used for watering of green areas and car washing. The objectives of the present work were to characterize the effluent and to propose a specific treatment to enable reuse of the effluent from the container washing ...

  • Reduction of chlorinous odor by the combination of oxidation and ion-exchange treatments

    To better control chlorinous odor in tap water, we assessed the performance of the combination of oxidation (ozonation or advanced oxidation processes, AOP) and ion-exchange treatment. In this process, the hydrophilic neutral fraction (a major dissolved organic matter (DOM) fraction) is converted to ionic species, and these ions and ammonium ion are effectively removed during ion-exchange ...

  • Removal of Cryptosporidium by wastewater treatment processes: a review

    Cryptosporidium is a protozoan parasite that infects humans and various animal species. The environmental stability and the low infectious dose of Cryptosporidium facilitate its transmission by water and food. Discharge of untreated wastewater may result in waterborne or foodborne Cryptosporidium outbreaks, therefore a suitable treatment may prevent its ...

  • The Future in Water Treatment - An SA Water Perspective

    Adelaide’s water quality has been the subject of adverse media comment in regard to taste and odour for years. At times, algal taste and odours are evident due to the majority of water being sourced from the River Murray plus reservoirs in the Adelaide Hills – a primary agricultural area. Further, customers complain about chlorinous taste and odour in the distribution systems. Despite all ...

  • Characteristics of natural organic matter and formation of chlorination by-products at Masaka waterworks

    To minimise the formation of chlorination by-products (CBPs) it is imperative that attention is directed towards the structure and occurrence of natural organic matter (NOM) in raw water sources, and its flow and fate during water treatment processes. In this study, an assessment of the characteristics and flow of NOM along the treatment train at the full scale treatment plant at Masaka, Uganda, ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...

  • Biological iron and manganese removal, pilot and full scale applications

    Both manganese and iron are found in surface and ground waters at varying concentration levels. When present even at low concentrations they can be linked to the following problems: discolouration, turbidity and taste problems or form slime and iron noxide or manganese dioxide accumulations in pipes. Both metals promote the growth of certain types of chlorine tolerant micro-organisms in water ...

  • Case study - Rapid removal of chloroethenes at industrial sites

    Description Air sparging with trenches had failed to remove groundwater and soil contamination at an industrial Superfund site in Piedmont soils in South Carolina.  The major contaminants of concern were cis 1,2-dichloroethene (DCE) and trichloroethene (TCE) ranging from 0.5 to 2.0 mg/L.  The treatment area was approximately 15,000 square feet. Ozone sparging was ...

  • New Treatment Technology Targets TOC/DOC Removal at Florida Utility

    Turn on any tap in Palm Springs, FL, and you will get crystal clear water. It has no odor, no metallic taste and compares favorably with most bottled waters. The residents are, quite naturally, very happy with it. Getting clean, refreshing water in Palm Springs was not an easy task. The ground water supply in South Florida typically contains large amounts of total organic carbon (TOC) in the ...

  • Improving TOC Removal to Achieve EPA DBP Compliance at the Green Valley WTP

    The Green Valley Water Treatment Plant (WTP) draws its water from two sources to supply Suisun, CA and surrounding communities. The WTP’s distribution system is very long resulting in lengthy detention times where free chlorine used for disinfection reacts with total organic carbon (TOC) to form high levels of Total Trihalomethanes (TTHMs). The Green Valley WTP was unable to adequately reduce the ...
