Leachate Treatment Options

For a new MSW landfill site, and assuming that it will be lined and capped, there are several leachate treatment options to consider before deciding on the type of leachate treatment system that will be needed.

The Most Common Leachate Treatment Options

The most common options to be considered are:
1. Avoid all leachate treatment on site, and instead tanker the leachate off site to a suitable leachate treatment facility which might be a sewage treatment works, or an industrial effluent treatment facility. Both of these would in the UK need to be in possession of a permit to treat non-hazardous liquid industrial effluents.
2. Build a dedicated leachate treatment plant on the landfill site to treat all the leachate produced by the landfill. (A discharge of the treated leachate effluent will need to be made to a local watercourse, or a soakaway (subject to compliance with the EU Groundwater Directive).
3. Ditto (2.) but the leachate treatment plant just sized to treat the baseline leachate flow produced by the landfill and the long-term post restoration capping leachate flow rate predicted. Excess flow would in this case be tankered away during wet weather periods.
Every landfill is different and the preferences of landfill operators also differ widely.
This means that these options should be considered at the start of the landfill development process, and the best option selected according to site specific requirements.
