Biological Nitrification Process with SEBS

Introduction:
Ammonia is a compound made up of nitrogen and hydrogen, with the molecular formula NH3. At room temperature it’s a gas but because it can form hydrogen bonds, it dissolves extremely well in water.

Nitrogen appears in wastewater as ammonia, nitrite, nitrate and organic nitrogen. Organic nitrogen decomposed to ammonia, which in turn on one and is assimilated to bacterial cells, leading thus to net growth, on the other hand is oxidized to nitrite and nitrate. In a second step, nitrate is converted to gaseous nitrogen and is removed from the wastewater. Denitrification is known to proceed as conversion of nitrates to nitrites and subsequent conversion of nitrites to nitric oxide, nitrous oxide and nitrogen gas. Nitrifying organisms are present in almost all biological treatment processes, but usually their numbers are limited, depending on the mean cell residence time (because of the threshold effect) and on the BOD5/N ratio. In most conventional activated-sludge processes, with a BOD5/N ratio of 3, the fraction of nitrifying organisms is estimated to be considerably less than 0.083, while for BOD5/N ratiosof 5 to 9, the estimated percentage is between 0.054 and 0.029 (Metcalf and Eddy, 1991). Suspended-growth nitrification and denitrification.

SEBS biologically oxidize the ammonia to nitrate and nitrite. During this process nitrifying SEBS bacteria converts ammonia to harmless nitrogen gas (N2) and continues to brake down hydrogen bond and digest organic matter and further lowering ammonia concentration in wastewater.

Application Method

During winter months (for waste water lagoons and ponds) if iced over, cut or brake open small opening and holes to help release trapped ammonia gas (N2) From below the ice cap.

During summer months regular use of SEBS and aeration will help lower ammonia concentration to allowable discharge limits.

Ponds and Large Lagoons:
Use 1 gal to 100000 thousand gal of water for reg. maintenance, for worse problem use 2 gal to 100000 gal of water.

How to Use:
For best results. SEBS can be sprayed on the top surface of pond and lagoons.
Apply threw out flow pipe in to the lagoon or pond. The mixing action will help speed up the process.
