The Top 5 Steps to Designing a Leachate Treatment Process
"Designing a Leachate Treatment Process is a complex task given the many possible process options available
nowadays for leachate treatment, but just as in so many tasks, following simple steps can produce the most
Today, people are facing many challenges. To select and operate a successful leachate treatment process is a
challenge many people face daily. A lot of folks have great results so are successful. Other folks struggle but
just do not appear to make any real progress. Many individuals work tirelessly at it but get few good results. What
is the difference here, the key ingredient to success? And How could you become one of those that succeeds?
Success will depend on making a good plan, an essential factor in knowing what to do and why, before you start.
It's easy whenever you get each of the steps organized before you start. So how about yourself? Do you really want
to win at the selection and operation of a successful leachate treatment porcess ? Then you really should study and
discover what's important first. Quite simply, you need to build up your knowledge.
Here are 5 steps to take to greatly boost your prospects of succeeding to select and operate a successful leachate
1. The first thing to decide is where the treated effluent will be discharged to. So why might this make a
difference? The degree of purity which the leachate treatment process will have to achieve will vary with the
discharge type, so you should apply for a watercourse discharge consent or a discharge to the public sewer via a
pipeline as the lowest cost options in most locations.
O.K., so when I follow this recommendation, what might one expect to occur? The body responsible for issuing the
consent will provide a list of contaminants and concentrations for those, above which the discharge consent or
permit will prohibit discharge. This provides the target discharge water quality which the leachate treatment
process will have to achieve reliably.
2. Predict the raw leachate quality which will apply when it is removed from the landfill for treatment. The reason
that is important is that This is the starting point for the leachate treatment process design. It also could be
important since weaker leachate will quite possibly be best treated by a different process to the strong
3. Calculate the volume of leachate expected to need treatment. The reason for this is that the larger the volume
which must be treated, and the stronger it is, the larger the leachate treatment plant will have to be. One other
reason in its favor is the landfill operator will become very aware of the cost of leachate treatment process, and
be encouraged to minimise leachate generation by covering the site etc, as soon possible to keep the waste dry/keep
the leachate which will require treating to as low a volume as possible.
4. Carry out water quality analysis for trace dangerous/ toxic chemicals which may be present in the leachate.
Alright, so what is significant with this? The presence of hazardous substances may render the process design
worthless, unless a check is carried out for any possible side effects or reactions which may hinder biological
Might there be one more reason why?
Operating a successful biological leachate treatment process requires a full knowledge of incoming leachate
quality, the level of conatminants requiring removal for aeration oxygen demand assessment, and reactor sizing
requirements, plus the presence of any inhibitory substances.
5. Use the data collected under the preceding steps to select a primary leachate treatment process, and then any
tertiary / polishing stages required to provide a leachate treatment process which will comply with the discharge
Just what exactly could be said in favor of this?
Choosing the primary stage primary leachate treatment process is important as this is where in excess of 90% of the
overall contamination will be removed and follow that by the additional process or processes needed for the plant
to work correctly.
What alternative reasons might there be in favor of this?
Get the most important part of the leachate treatment process design right and you are well on the way to a
successful leachate treatment process design in total.
For the very best results in selection and operation of a successful leachate treatment process, just stick to the
5 tips above. Then succeed and luxuriate in the entire benefits, enjoyment and fruits which go with that success.
Neglecting them will set you up for mediocre results. Plus, worse outcomes than those you may normally
