Air stripper stage efficiency

Water Sci Technol 1 June ; 79 11 : — The first-stage air stripping process before hydrolysis acidification could achieve a significant removal of NH 3 -N The group with air stripping had more abundant microbial communities and a more effective organic degradation performance in hydrolysis acidification than that without air stripping. The second-stage air stripping removed NH 3 -N released from hydrolysis acidification, and significantly reduced the TN concentration in effluent. Moreover, toxic and refractory organic compounds prevail in coal gasification wastewater, which will cause irreversible reduction of biological treatment performance Li et al. In brief, coal gasification wastewater is a typical highly toxic, harmful and refractory wastewater.

Air stripping of ammonia and methanol in a bubble‐cap column

Air stripping is the transferring of volatile components of a liquid into an air stream. It is an environmental engineering technology used for the purification of groundwaters and wastewaters containing volatile compounds. These include BTEX compounds benzene , toluene , ethylbenzene , and xylene found in gasoline , and solvents including trichloroethylene and tetrachloroethylene. Ammonia can also be stripped from wastewaters and liquid digestates often requiring pH adjustment prior to stripping. Although any device that promotes contact between air and water strips some volatile compounds, air strippers are usually packed towers or tray towers operated with countercurrent flow of water and air.

Dye and organic matter as well change in disinfection practice may generate taste and an odorous compound in treated water. According to low efficiency of conventional methods to remove taste and odor compounds, present study was aimed to evaluate the performance of air stripping tower- Poly Aluminum Chloride PAC integrated system to remove odor and taste, dye and organic materials from drinking water.
