The Effect Of Preozonation On The Control Of Trihal Omethane Formation

摘要: Abstract A study was made to obtain a better understanding of the manner in which preozonation affects trihalomethane (THM) formation with respect humic acid, citric and 11 aromatic compounds were components all dilute aqueous medium. Ozonation before chlorination is able tonotonly decrease, butalso increase concentrations THM precursors. The are inherently high precursors, such as resorcinol, aniline, salicyl-aldehyde, phenol, andp-hydroxybenzoic controlled tothe inthe amount ofozone consumed, but have essentially no or alow potential for chloroform formation, hydroquinone. salicylic methoxybenzene. benzaldehyde. benzole produce their maximum levels at certain value ozone consumed. When 1mg organic carbon consumes more than 8 mg ozone, from thetested isdepressed by ozone. Aliphatic carbonyl products ...
