Air stripping meaning

Air stripping is the transferring of Volatile compounds have relatively high Air strippers [ ] Although any device that promotes contact between air and water strips some volatile compounds, air strippers are usually packed towers or Packed Tower Strippers [ ] Packed towers, such as shown in Figure 1, use a distributor placed at the top of the tower to evenly distribute engineered plastic, ceramic, or metal packing to maximize air-water contact. Design criteria for packed towers include surface area provided by the packing, column height and diameter, and air to water flow rates. Designers of air strippers want to obtain the largest air-water surface contact in order to reach maximum efficiency of removing contaminants Of the two types of air strippers, packed strippers tend to be more efficient at removing contaminants than sieve tray towers. Packed towers remove 99% of volatile organic compounds due to their high Henry's constant and the high air-water surface contact of the system. Tray Tower Strippers [ ] Sieve tray towers use a similar process to packed towers, but instead of packed materials being evenly distributed, the materials are separated into several trays with holes that allow water to drip through them. An electric air compressor is typically positioned at the bottom of the system where the air from the fans travels through the holes and becomes exposed to the water. A natural draft can also be used as an air source to separate contaminants from the water. A...

Air sparging, also known as in situ air stripping in situ volatilization is an in situ remediation technique, used for the treatment of saturated Mechanism [ ] Air sparging is a subsurface contaminant remediation technique that involves the injection of Methods and treatment [ ] The air sparging system treats the off-gases (referred as contaminated vapors and extracted air). The vapor is treated with granulated Applicability [ ] Air sparging is generally applied for commercial usage. Air sparging contaminant groups are VOCs and fuels found in groundwater. Air sparging is usually applied to the lighter gasoline constituents such as Arsenic-contaminated groundwater can be treated by air sparging to remove a certain percentage of arsenic in a solution of iron and arsenic at a molar ratio of 2. Treatment using air sparging is beneficial as groundwater contains high amounts of dissolved iron, which contains the theoretical capacity for the treatment.
