  • CO2 degasification air stripping tower design - Case study

    Background - Water Chemistry Controls the Design A common method to adjust pH of water - typically well water intended for potable use - is to pass the water through a packed tower. Such towers intended to degas the water was also commonly called 'air strippers'. This is because the water is passed down over a bed of 'packing1 as air is blown into the bottom of the tower to pass up and out ...

  • Radon Air Stripping of Well Water

    Radon is Frequently Found in Ground Water Radon, symbol Rn, atomic number 86, is a colorless, odorless gas at ambient conditions. It is the heaviest element of the Noble Gas family. As such it is extremely stable and unreactive chemically. But it also is highly radioactive. Its half-life is only 3.8 days. Both Thorium, symbol Th, atomic number 90 and Uranium, symbol U, atomic number 92, have ...

  • Ammonia nitrogen removal and recovery from acetylene purification wastewater by air stripping

    Ammonia nitrogen (NH4-N) contaminated wastewater has posed a great threat to the safety of water resources. In this study, air stripping was employed to remove and recover NH4-N from acetylene purification wastewater (APW) in a polyvinylchloride manufacturing plant. Investigated parameters were initial APW pH, air flow rate, APW temperature and stripping time. The NH4-N ...

  • E-Z Trays at Hard-to-Access Site - Case Study

    E-Z Tray® (U.S. Patent Number 5,518,668) Air Strippers have always been known for their ease of access and cleaning, but for this special site, an old industrial building in Brooklyn, New York, they also had to be installed without the use of any heavy equipment. The site was using a competitor's air stripper on the second floor of an older building and the units had become very ...

  • Santa Cruz Meets THM/DBP Challenge with Unique Air Stripping Process - Case Study

    Summary Santa Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. The City evaluated various aeration treatment processes and chose an E-Z ...

  • Treating a Gasoline spill - Case Study

    Treating a Gasoline Spill in New York Overview Gasoline spill in high value residential area. Space for process equipment limited. Need for low profile - sound and appearance. Strippers housed in metal shipping containers. ...

  • Simultaneous regeneration of exhausted zeolite and nitrogen recovery using an air stripping method at alkaline pH

    Ammonium nitrogen recovery using natural zeolite from the permeates of anaerobic membrane bioreactors was investigated with batch and continuous experiments. Regeneration of exhausted zeolite was compared between mechanical shaking and air stripping, and experimental results showed the superiority of air stripping over the shaking. Liquid circulation and air flow rates were optimized in a ...

  • RainWise Telemetry MK-lll-LR Air Strip Project - Case Study

    This project required weather data to be monitored at a remote air strip in a valley, which was then sent via the mobile phone network back to Sydney so the owner could monitor weather conditions before flying out to this remote location. The only Next G phone signal was located almost 2km away through dense bush on the side of a hill. The solution required a three part approach; A high quality ...

  • Application of ultrasound and air stripping for the removal of aromatic hydrocarbons from spent sulfidic caustic for use in autotrophic denitrification as an electron donor

    Spent sulfidic caustic (SSC) produced from petroleum industry can be reused to denitrify nitrate-nitrogen via a biological nitrogen removal process as an electron donor for sulfur-based autotrophic denitrification, because it has a large amount of dissolved sulfur. However, SSC has to be refined because it also contains some aromatic hydrocarbons, typically benzene, toluene, ethylbenzene, xylene ...
