  • Determining Proper Cooling Tower Size

    To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

  • A moldy summer and the 3 H’S hot-humid-hurricanes

    A HOT WET SUMMER Once again, we’ve entered the hurricane season, when hot humid air envelops most of North America. Beginning in the Spring and lasting until the first frost of Autumn, the air is typically well above 60% Relative Humidity, which is ideal for promoting the growth of mold. The official Hurricane season runs from June to September, and even though they may not qualify as ...

  • Why is Humidity / Moisture Control Important in a Fuel Cell?

    The root of all of this is that Nafion membranes must stay hydrated to function properly. If they are not fully humidified the conductivity decreases and therefore more of the electricity is converted directly to heat before it leaves the membrane (I2R heating). If it gets too dry it basically stops functioning as a proton transporter. ...

  • Producing drinking water from seawater with waste energy

    German firm Taprogge and ESACO (Vietnam) are jointly investing in seawater desalination technology in the country. The Saigon Times Daily had a talk with Detlef Taprogge, CEO of Taprogge, about the Taprogge Terrawater Technology during a recent demonstration of a system using this tech in HCMC’s Can Gio District. Excerpts: The Saigon Times Daily: What is the specific of this ...

  • Determination of the relative and absolute humidity in Compost piles by differential pectroscopy using Tuneable diode lasers

    The composting of biological waste is an important step towards the establishment of closed cycles of matter. A constantly high quality of the compost is, however, of utmost importance for the deliberate re-introduction of compost into the environment. The quality of the compost produced is determined by a very complex biological process during which the organic wastes are converted with the aid ...

  • Keep your air clean with Wet Dust Collectors

    Wet dust collectors use liquid — often but not always simple water — to capture and separate dust, mist, fumes, and other particulate matter from a stream of flowing gas — often but not always simple air. Some wet dust collectors spray liquid in a sheet across the stream of gas; others bubble the gas through ...

  • How industrial air-cooled chiller rentals benefit you

    Summer will be here before you know it and with it will come soaring temperatures. Few other states know heat and humidity like the southern states, and going without cool air is simply not an option for their hardworking residents. For the people in these states, an industrial air-cooled chiller is a useful and viable option to keep ...

  • Indoor air quality can be improved by employing plants as walls

    The practice of planting ivy to climb up the walls of buildings has existed for centuries. Now, the trend towards sustainability and green building practices can lead to the development and use of living walls as a means of filtering and improving a building’s indoor air quality. Green walls are a living, breathing, regenerating type of cladding that can be as simple as a living art installation ...

  • Water and vapor movement with condensation and evaporation in a sandy column

    The diffusion of warm, humid air into an initially cold, dry, sandy column was analyzed to study the movement of water vapor and liquid water under nonisothermal and low water content conditions. The analysis was performed using the HYDRUS-1D code. While the water retention curve of sand was measured experimentally, the unsaturated hydraulic conductivity function was inversely estimated from the ...

  • Energy-efficient operation of two-pipe fan-coil unit system with independent fresh air supply

    Year-round energy-efficient operation is presented for a two-pipe fan-coil unit air-conditioning system with independent fresh air supply. The study investigated two typical in-room fan-coil operating modes: the dry fan-coil mode in which the room cooling coil does no latent cooling and the wet fan-coil mode in which the room cooling coil is used for dehumidifying a part of moisture from ...

  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Case study - Deodorization at waste water treatment plants

    The presence of microorganisms in wastewater causes a decrease in dissolved oxygen levels due consumption by the organisms’ metabolic processes. The more microorganisms there are, the greater the biological demand for oxygen. When this demand exceeds that which can be provided by the exchange of air, an anaerobic process begins, thus creating a reducing environment that favours the ...
