  • Energy recovery from biogas purification

    Energy recovery from biogas is becoming more common, but the processes are hampered with the presence of hydrogen sulfide (H2S). Biogas is a mixture of methane and carbon dioxide (CO2) and is often contaminated with toxic quantities of H2S. Sources of biogas are: municipal landfills that produce landfill gas (LFG), wastewater treatment plants, industrial plants, and large scale livestock farms. ...

  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • Performance of Palladium Diffusers for Reliable Purification of Hydrogen

    Hydrogen generators are now becoming an essential component in many laboratories with greater gas consumption levels. Generators are considered to be preferable to cylinders, particularly because of the safety concerns about having high pressure hydrogen in the laboratory working environment. Hydrogen generator systems typically produce Hydrogen with a two-phase system. Hydrogen is first ...

  • The value of anaerobic purification for pulp and paper mill effluents

    In comparison to the food industry, anaerobic treatment had a later and a slower start in the pulp & paper industry. The first plants were installed in the beginning of the eighties and at the moment the number of projects that has been counted is approximately 140. Many of these plants have been installed as a pre-treatment stage before an activated sludge plant and reduce at least 80% ...

  • Purification Of Industrial Gases: Chemical scrubber vs Physical Adsorption

    Gas purification using a chemical scrubber is a technology that has been applied successfully for decades for the purposes of eliminating contaminants in a gas flow. However, although it is a technique that is easy to design and quite flexible, it entails certain disadvantages and/or risks. In recent years there has been considerable interest in developing alternative ...

  • gaiasafe filter products for drinking water purification - Case Study

    Problem In some water works chlorination of drinking water is used to eliminate mikrobes. Chlorinated water may have disagreable taste and smell. Some water works use aluminium salts to clean the water. This leads to low concentrations of aluminium in drinking water. Today it is known that aluminium may be toxic to men. Old piping installations inside or outside private homes often where ...
