Abstract
The influence of 0, 1.5 and 3% NaCl on the activity of halotolorent microorganisms was investigated in a pilot-scale, subsurface flow, and sand-gravel constructed wetland. Also, the influence of aeration and aeration with 2 g/L of saccharose in synthetic wastewater was investigated. Measurements of electron transport system(ETS) activity, optical density at 600 nm and CO2 concentrations in soil of the pilot plant indicated that inoculated halotolerant microorganisms were not affected by the changes in salt concentrations and they were not affected by 3% salinity. Key words: Constructed wetlands, saline wastewater, halotolerant microorganisms.
