  • Water treatment membrane coating promises chemical-free virus removal

    A novel material coating for water treatment membranes promises to improve the removal of water-borne viruses during treatment. This hydrogel coating, known as a zwitterionic polymer hydrogel, was created by scientists from Ben-Gurion University of the Negev and the University of Illinois at Urbana-Champaign. The virus-fighting membrane was created by grafting the new hydrogel coating onto ...

  • Looking Beyond Chemical Water Treatment Case Study

    When you think of an environmentally friendly company, a steel processing plant does not typically come to mind. However, Stripco Inc. of Mishawaka, IN, a manufacturer of production-ready, cold-rolled steel coils, is the exception. In August of 1995, Stripco made a wise decision that also proved to be cost-effective and environmentally- friendly when they installed a Superior Environmentalist ...

  • Drinking Water Treatment Process

    Most drinking water comes from a surface water source, such as a lake or river, or a groundwater source, such as a well or spring. This water requires treatment before it can be safely consumed; the level to which the water is treated depends on the source of the water and also on federal regulations. In the United States, for example, the Safe Drinking Water Act was created by the Environmental ...

  • Ultraviolet Light Oxidation of Free-Chlorine in Water

    Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

  • Exploring the potential synergistic effects of chemical disinfectants and UV on the inactivation of free-living bacteria and treatment of biofilms in a pilot-scale system

    The main objective of this study is to explore possible synergistic or additive effects of combinations of chemical disinfectants (sodium hypochlorite, peracetic acid, hydrogen peroxide, chlorine dioxide) and UV in their efficacy in inactivating free-living bacteria and removing biofilms. In contrast to most studies, this study examines disinfection of municipal water in a pilot-scale system ...

  • The Best Water Treatment Systems of 2017

    To be properly hydrated, most people need to drink around two liters of water a day. Because we drink so much water, trace amounts of impurities, chemicals, and hard metals can build up in our bodies over time. Water has become the focus of many health-interested individuals in recent years. For businesses that need clean water, like labs or manufacturing companies, keeping water as clean as ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?

    Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

  • Chiller & cooling tower water treatment - case study

    Overview There are three main challenges for treating cooling water in both open and closed loops: scale, corrosion and biogrowth. Water System Challenges The traditional chemical treatment calls for chemicals to deal with these challenges. When scale is present, the condenser’s ability to transfer heat is reduced, causing higher pressure and higher ...

  • HydroFLOW and Cooling Tower eliminating the need for chemical treatments case study

    Misericordia Hospital – Alberta – 2011 In June, 2011 Misericordia Hospital began a three-month trial on two of the three cooling towers in its facility. The test compared the effectiveness of HydroFLOW in eliminating limescale and algae vs. standard chemical treatment. Standard chemical treatment was removed from Cooling Tower #3 and a P-160 HydroFLOW unit installed. Standard ...

  • Surveillance of the chemical and microbial quality of drinking water for safe water supply in an urban area

    To ascertain the quality of drinking water, surveillance of drinking water quality was conducted in Bhopal. The water supply to water treatment plants (WTPs) is from Kolar dam and Upper Lake. There was no significant change in water quality at the Kolar WTP on a day-to-day basis except in summer, when the manganese content of raw water was 0.3–0.4 mg/L, which was removed during treatment. The ...

  • An essential guide to water treatment solutions & its steps

    The scarcity of water is one of the biggest issues faced by the current generation. Due to the changes in climatic pattern, rising number of industrial employments and other commercial residues, the remaining water sources have kept on being polluted, and hence, the level of drinkable and safe water is dropping at an alarming rate. Currently, while the level of wastewater is rising, on the other ...

  • What do you understand by water treatment systems?

    Wastewater treatment is a feasible practice that helps to conserve water all across the various parts of the world. Treating the wastewater is important as to save the environment, human and the animal life. Wastewater usually comes from households, dishwashers, toilets, sinks, bathrooms, factories, and industrial units. The wastewater generally contains harmful substances both for ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location.
