Sewage Parameters 6 Part 2: Total Nitrogen

Hey, today we are going to discuss how to actually denitrify (the conversion of NO3 to Nitrogen (N) and Oxygen (O2) gas which is given off in the atmosphere) which is the second step in the process to lower Total Nitrogen in treated sewage effluent and is termed Denitrification.

Sewage Parameters 6 Part 1: Total Nitrogen

Hey, we are back to discuss how to lower the total level of Nitrogen from inlet to outlet of a sewage treatment plant.  Total Nitrogen is often abbreviated to TN or N.  The reduction of TN is a two stage process involving the conversion of Ammonia (NH4) to Nitrates (NO3) termed Nitrification, followed by the conversion of NO3 to Nitrogen (N) and Oxygen (O2) gas which is given off in the atmosphere, termed Denitrification.

Sewage Parameters 5 Part 2: Ammonia (NH4)

Hey, continuing on from the last entry in our education blog, we will now go through a simple example of how to calculate the extra package effuent treatment plant capacity required in term of Population Equivalents (PE) to achieve the correct level of Ammonia removal (NH4) from wastewater effluent. More on the theory can be found in our last blog entry on the theory of Ammonia removal. The process is also know as Nitrification, meaning the conversion of Ammonia to Nitrate (NO3)

Sewage Parameters 4: Phosphorus (P)

Continuing on from Population Equivalent (PE) the next parameter is Phosphourus (P)  The reason that Phosphorus is often a focused on in wastewater effluent is that it is an essential mineral in the growth of algae and other biological organisms along with Nitrogen.
