Air Ammonia Stripping

Air Ammonia Stripping is a leachate treatment process which is now largely outdated and seldom used. During the 1980s in the United Kingdom it was seen as a potential physico-chemical leachate treatment process which would be suitable for the treatment of leachate from sanitary (lined and capped) landfills, however, although a number of pilot scale […]

Landfill Leachate Composition

Landfill leachate composition for United Kingdom Landfills was first published in the Waste Management Papers published by the UK Department of Environment. Waste Management Paper 26 contains the most recent table of Landfill Leachate Composition before the WMP series was superseded by later documents, notably the DoE’s Leachate Report of 1995. However, the original table, […]

How Do You Treat Leachate?

First of all when asked the question, “How Do You Treat Leachate?”, we would like to make a distinction between true treatment which involves converting environmentally damaging substances to less, or non-toxic, ones, and simply concentrating the contaminants from the water in leachate to give a volume reduction. In the water industry both are known as […]

Anaerobic Digestion of Landfill Leachate for Energy Generation: Pipe-Dream or an Opportunity?

Anaerobic digestion is becoming increasingly popular in this age of high energy prices, and many more people are realising that whereas aerobic treatment systems consume large amounts of expensive energy, anaerobic digestion is a process which does the opposite. In fact it produces a net energy output.   It is not surprising therefore, that many […]

Leachate Quality from Landfilled MBT Waste

Leachate Quality from Landfilled MBT Waste

In recent years there has been a trend toward MSW leachates from Sanitary Landfills throughout the world becoming more similar, however, as Mechanical Biological Treatment (MBT) is increasingly implemented and more Mechnanically Sorted Organic Residue (MSOR) [also known as “residual waste”] is produced in the supply area for a landfill, so the leachate quality of […]

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.
