Triethylene glycol (TEG) liquid was used to a liquid membrane material for indoor air humidification. An novel surface-soaked liquid membrane under vacuum permeation was developed using a hydrophobic microporous membrane, only one surface of which was hydrophillic-treated to contain TEG by corona treatment. A flat membrane module with 0.39 m2 area was placed in outdoor, and water vapor was permeated...
Based on the monitoring data of June 2009 from Xinxue River Constructed Wetland, Shandong, China, the research was done to reveal the variations of COD, NH3-N, TN and TP in multistage series constructed wetland system. The results showed that the constructed wetland had a fairly good purification efficiency to the polluted water of Xinxue River, and the concentration of various pollutants gradually...
This paper discuss the energy consumption problem of dissolved air flotation through theoretical analysis and experimental research methods. According to surface free energy principle,we can get that the energy dissipation of traditional pump aspirated type dissolved air flotation experiment system is 8359.4 times theoretical value effective power by calculation. Therefore, the potential of energy-saving...
