Mogden Calculator - Trade Effluent Charge Formula Calculator

We plan to add a number of leachate software applications to this page over the next few months, which our visitors can download and install, and which will provide solutions to a number of problems experienced by leachate treatment plant operators. Our first two are now available, a handy conversion calculator (see below), and (see right) our Trade Effluent Charges Calculator here.

Ammonia to Ammoniacal Nitrogen “Expressed as N” – Free Conversion Calculator

There are two methods used by analytical laboratories for expressing the quantity of ammonia in contaminated water. The first is that provided bythe majoirty of water quality analytical laboratories when reporting the quality of a polluted water. They provide a weight of ammonia as the weight of the nitrogen (elemental N), “ammoniacal- N” and that is the method¬† used by the Enviroment Agency UK.

However, some water quality labs report the weight of “ammonia”, (ie the whole NH4 molecule) which includes the weight of the hydrogen atoms as well as the nitrogen atoms, and landfill site operators may at times erroneously¬†think that they are closer to their maximum permitted ammoniacal nitrgen strength for discharge, than they really are.

To help landfill operators correct for the difference between the two methods of expressing ammoniacal nitrogen values we devised the software below, which will walk you through how to calculate Ammoniacal-N (ammonia expressed in mg/l as N) concentrations (as used in UK Trade Effluent charging and dicsharge consents and environmental permits).

Get started now using our software, in three steps, as follows:

1. Simply download the zipped file below and unzip it into its own new directory location on your hard drive where you will be able to go back to it later.

2. Double click on the executable file (file extension “.exe”) called “ammonia-converter.exe”, and the software will load up and you can start to use it.

3. Follow the instructions given inside the software program.
