  • 3 Water Utilities that Lowered their Arsenic Levels with AdEdge

    Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the ...

  • 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 ...

  • Application of chemical oxygen demand to drinking water

    “This study investigated the use of a photoelectrochemical chemical oxygen demand (peCOD) analyzer for the detection of model organic compounds and natural organic matter (NOM) from four drinking water treatment plants in Nova Scotia, Canada. Most model organic compounds showed ...

  • Biological Filtration: Future of Drinking Water Treatment

    Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. ...

  • Algae control in drinking water treatment - case study

    For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to check the process efficiency, which showed problems ...

  • 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 ...

  • Chemical analysis of drinking water of villages of Sanganer Tehsil, Jaipur District

    Abstract Due to pressure of human activity, urbanization and industrialization, the groundwater sources are degraded gradually; therefore pure, safe, healthy and odorless drinking water is a matter of deep concern. There are many pollutants in groundwater due to seepage viz. organic and inorganic pollutants, heavy metals, pesticides, fluorides etc. In Rajasthan state, all 32 districts are ...

  • Variations of chemical quality for drinking water sources in zarand plain

    The ultimate source of most dissolved ions in water is the mineral assemblage that occurs in rocks near land surfaces. The solids that dissolve into groundwater from this point, form part of the geochemical. Rock composition, purity, crystal size of its minerals, rock texture and porosity, regional structure, degree of fissuring and length of previous exposure time also influence the composition ...

  • Evaluation of control strategies for drinking water treatment plants using a process model

    This research adds a method to evaluate control strategies to the design methodology for drinking water treatment plants. A process model dealing with parameters related to the calcium carbon dioxide equilibrium was set up. Using the process model, the existing control strategy was compared with a new control strategy and the effects of two different sets of input data were studied. It was ...

  • 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, ...

  • Behaviour of brominated and chlorinated flame retardants during drinking water treatment

    Flame retardants are chemicals that are added to plastic materials in order to prevent them from catching fire and to slow down the burning process. Due to the widespread occurrence of flame retardants in the environment, it can be expected that especially the more hydrophilic compounds already contaminate raw water resources of water utilities. In this paper results of laboratory-scale ...
