  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • Effects of current density on copper nanoparticle prepared by electrochemical method

    Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • A comparative evaluation of palladium and platinum nanoparticles as catalysts in proton exchange membrane electrochemical cells

    The goal of the present study is the development and comparative characterisation of carbon-supported and nanostructured Pd- and Pt-based electrocatalysts for hydrogen oxidation in Proton Exchange Membrane (PEM) H2/O2(air) fuel cells and proton reduction in PEM water electrolysers. Catalysts have been synthesised in a solution using a combined impregnation/reduction polyol method. They have been ...

  • The use of response surface methodology for modelling and analysis of water and wastewater treatment processes: a review

    In recent years, response surface methodology (RSM) has been used for modelling and optimising a variety of water and wastewater treatment processes. RSM is a collection of mathematical and statistical techniques for building models, evaluating the effects of several variables, and obtaining the values of process variables that produce desirable values of the response. This paper reviews the ...

  • Degradation of azo dyes in water by Electro-Fenton process

    Abstract The degradation of the azo dyes azobenzene, p-methyl red and methyl orange in aqueous solution at room temperature has been studied by an advanced electrochemical oxidation process (AEOPs) under potential-controlled electrolysis conditions, using a Pt anode and a carbon felt cathode. The electrochemical production of Fenton's reagent (H 2O 2, Fe 2+) allows a controlled in situ generation ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...

    Untitled Document ABSTRACT Monitoring of recreational beaches for fecal indicator bacteria is currently performed using culturebased technology that can ...

  • Falling Oil Price Forces Operators to Find Cost Savings in Water Management

    When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...

  • ITS marketing manager quoted in WaterTech

    Professional, ethical testing will start you off on the right foot and will directly determine which services the customer may need. Many substances could be in a customer’s water, but, “It’s not necessary to test for every parameter; that’s what labs are for,” advises Rob Samborn, director of sales and marketing for HM Digital, a Los Angeles-based maker of water ...

  • Unmanned remote and wireless CDM monitoring case study

    Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...
