چکیده
|
This paper reviews both heterotrophic and autotrophic processes for the removal of nitrate from water supplies.the most commonly used carbon sources in heterotrophic denitrification are methanol, ethanol and acetic acid.process performance for each feed stock is compared with particular reference nitrate and nitrite residual and totoxicity potential. autotrophic nitrate removal has the advantages of not requiring an organic carbon source;however the slow growth rate of autotrophic bacteria and low nitrate removal rate have contributed to the factthat relatively few full scale plants are in operation at the present time.
