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.

Leachate Fact File 2 – Contaminants Found in Leachate: Phenols

Be one of the first to buy this fact sheet! It’s the 2nd of a planned series of Leachate Contaminant Fact Files!

Our leachate fact sheets are based upon research carried out for the UK Department of Environment in the mid-1990s, updated and presented in bite-sized documents.

Penols Fact File 3D image

Designed as reference sources for leachate treatment scientists, regulatory bodies, and interested owners of landfill sites, these Fact Files come complete with a reference list for the original information sources, for those seeking to do further studies into the subject of each Fact File. (In this Fact File we cover a very important water contaminant which has been very controversial, and still does concern very many people.)

Although, this Fact File has been specifically created with the leachate management/ water quality specialist in mind, it contains much information which is relevant to the assessment of PCB hazards in any water body, and the environment generally.



This document is an ebook which is available as a Acrobat™ PDF file for immediate downloading at any time, day or night.

Store it on your hard drive for future reference
or print it out and keep it – it’s your choice!

We use Paypal as our payment processor, we will not be given your credit card details.

We will NEVER
sell or otherwise distribute your personal information!

  • Find out just how hazardous Phenols are likely to be when found at trace concentrations in leachate
  • Be able to assess the risk to the environment of Phenols at specific landfill sites by holding an understanding of the nature of the Phenol risks in cancer etc
  • Understand in principle how Phenols get into leachate
  • Find out how Phenol concentrations found commonly in leachate and compare this with other examples of Phenols contaminated water


Q: Are these fact files based upon information available elsewhere on the internet?

A: No. They are based upon peer reviewed technical papers, government reports (most of which have been archived), and to some extent on specialist professional environmental (mostly subscription) magazine articles published in the last 20 years. At least 80% is not freely available on the web, even if you had unlimited time to seek it out.


The price of this Fact File will be £15 when the full series is published
however, you – as an early buyer will get an “early-bird” discount and pay
just £13.75 inclusive of VAT.

Just think of the time it would take you to research this information yourself, even if the information was freely available? This is high value, and very specialised, information, at a remarkably low price!

  • Find out just how hazardous PCBs are likely to be when found at trace concentrations in leachate
  • Be able to assess the risk to the environment of PCBs at specific landfill sites by holding a thorough understanding of the nature of the PCB threat and why it has caused all PCBs to have been banned
  • Understand in principle how PCBs build-up in living tissues
  • Be clear in your mind how it was that PCBs historically became known for their hazardous properties
  • Find out how PCB concentrations found commonly in leachate compare with other examples of PCB contaminated water, such as heavily trafficked highway rainwater run-off
  • Understand the reasons for the manner in which the whole family of PCBs have been analysed in the past for just a few of the many PCB isomers, and the limitations of some PCB analysis methods.
