I would not agree waterineyes, pesticides are chemicals disinfection is in regards to killing pathogens not concerned with the removal of pesticides.

australopithecus · Answer

I only half read most things sorry :S air stripping is for the removal of volatile gases, pesticides are not normally in gas form as they usually are wanted to coat the plant to prevent pests from eating said plant. Although, I did read a source that mentioned it is used in tertiary or primary treatment. I would go with carbon absorption here is a source that may be helpful I don't know http://www.water.siemens.com/en/applications/wastewater_treatment/tertiary_treatment/Pages/default.aspx

I would think they would use air stripping for removal of gases produced by microbes during secondary treatment not to remove pesticides
