  • How Installing Arsenic Drinking Water Treatment Can Save Your Life

    Arsenic is an element so associated with its toxicity and harmful effects on the human body that the word itself is often used for any kind of general poison. While the exact ways that exposure to the metalloid attacks various organs and systems is still not fully understood, studies throughout the scientific community are continually determining that ingesting arsenic through drinking water can ...

  • The Benefits of Biological Treatment for Drinking Water

    The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...

  • A solution to fracturing water supply and disposal issues

    “Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Drinking Water Aesthetics Improve with Ozone Treatment

    High quality water sources for municipal use are dwindling, forcing utilities to seek alternate water sources. Many times, aesthetics are the only problem preventing the use of these alternate water sources for potable purposes. Although typically used as a disinfectant, ozone offers municipal water purveyors the benefits of being the strongest commercially available oxidizing agent (Table 1). ...

  • Control-design methodology for drinking-water treatment processes

    The performance of a drinking-water treatment plant is determined by the control of the plant. To design the appropriate control system, a control-design methodology of five design steps is proposed, which takes the treatment process characteristics into account. For each design step, the necessary actions are defined. Using the methodology for the pellet-softening treatment step, a new control ...

  • Acute toxicity and inactivation tests of CO2 on invertebrates in drinking water treatment systems

    In addition to the esthetic problem caused by invertebrates, researchers are recently starting to be more aware of their potential importance in terms of public health. However, the inactivation methods of invertebrates which could proliferate in drinking water treatment systems are not well developed. The objective of this study is to assess the acute toxicity and inactivation effects of CO2 on ...

  • Multicriteria decision analysis for the selection of a small drinking water treatment system

    The selection of a small drinking water treatment system for a hydro-electrical plant is addressed within a multicriteria and participatory decision analysis process. As a first step, based on problem constraints, we identified and retained three water treatment systems alternatives. In close collaboration with the stakeholders, we then defined and obtained weights for criteria that take into ...

  • Evaluating a composite cartridge for small system drinking water treatment

    A pilot-scale evaluation was conducted at the U.S Environmental Protection Agency (EPA) Test & Evaluation (T&E) Facility in Cincinnati, Ohio, on a multi-layer, cartridge-based system that combines physical filtration with carbon adsorption and ultraviolet (UV) light disinfection to serve as a home-base water treatment security device against accidental or intentional contaminant events. The ...

  • Solutions for Safe Drinking Water Through Biological Water Treatments

    Most people across the U.S. expect to turn on their faucets and have immediate access to clean drinking water. The truth is, it wasn’t until 1974 that Congress passed the Safe Water Drinking Act with the goal of regulating the nation’s public water supply. Over the years, the SWDA has been amended to include water sources as well, such as rivers, lakes, springs and groundwater wells ...

  • Recycle of waste backwash water in ultrafiltration drinking water treatment processes

    In drinking water treatment, ultrafiltration (UF) membrane systems are generally operated at 90 to 95% recovery with production losses resulting from waste residual streams such as backwash water and clean-in-place (CIP) liquid residuals. In drought-prone regions, it may be desirable to apply alternative UF plant design configurations to increase recovery rates and minimize water loss. This ...

  • Safe drinking water and waterborne outbreaks

    The present work compiles a review on drinking waterborne outbreaks, with the perspective of production and distribution of microbiologically safe water, during 2000–2014. The outbreaks are categorised in raw water contamination, treatment deficiencies and distribution network failure. The main causes for contamination were: for groundwater, intrusion of animal faeces or wastewater due to ...

  • Natural Disaster Recovery & Drinking Water

    Clean water is one of the fundamental pillars of modern civilization, and a major priority for local and municipal government.  When disaster – hurricanes, tornadoes, earthquakes – strikes, one of the first priorities is to rehabilitate water treatment and distribution systems.  Water main and pipe breaks, pressure loss, and backflow can all act to introduce external ...

  • Enhancing climate adaptation capacity for drinking water treatment facilities

    Conventional water treatment processes (e.g., coagulation, flocculation, sedimentation, and filtration) are widely used for producing drinking water from surface water sources. Transient, gradual, or abrupt changes in source water quality that could compromise treatment effectiveness can be triggered by climate and related meteorological events, accidental or intentional contamination, ...

  • Use of horizontal flow roughing filtration in drinking water treatment

    In order to evaluate the feasibility of implementation of horizontal-flow roughing filtration for drinking water treatment a pilot was designed and run at the bank of Zayandehroud river near the village of Chamkhalifeh. Pilot running was performed in summer 2003 (July, August and September), when the quality of river water was in relatively worst condition. The filter is comprised from three ...

  • Fluorescent-conjugated MS2 as surrogates for viruses during drinking water treatment

    Microfiltration/ultrafiltration (MF/UF) membranes and ultraviolet (UV) light disinfection serve as attractive alternative technologies to aid utilities in complying with both the LT2ESWTR and Stage 2 D/DBP. However, both technologies are limited in their ability to remove viruses and at the same time there is a lack of methods to accurately demonstrate virus removal in full-scale settings. In ...

  • Drinking water: the problem of chlorinous odours

    Chlorinous off-flavours in drinking water are a leading cause of complaints to Australian water utilities and other utilities worldwide. The occurrence and causes of chlorinous odours in drinking water were investigated with the use of an odour panel, trained using a modified flavour profile analysis technique. A new system for classifying water types according to the causes of chlorinous odours ...
