The effective management of leachate within a site continues to present a challenge to landfill operators. Every site is different and demands a unique solution. At Biogas we have gained experience over a wide range of sites and installations and have developed effective solutions to the regular problems encountered.
Where the quantity of leachate to be pumped is variable and low, and perhaps distributed over a large area, then pneumatic cylinder pumps can offer particular benefits - and still fit within established gas wells for ease of installation. Similarly where there is an efficient leachate drainage system within the site which collects the leachate at one or two deep locations, then conventional submersible pumps can be effective.
Biogas have experience of a range of pumping methods and so can determine the most effective approach for individual sites, and provide a successful installation.
Discharge or Treatment
Output arrangements from the extraction system can be supplied to suit specific site requirements. Discharge can be pumped or by gravity, and the system supplied with automatic sampling and monitoring or linked to treatment plant. In some cases leachate recirculation may be used to optimise gas production, or spray irrigation for on-site disposal.
The Wider Perspective
Within many sites the management of leachate is directly linked to the management of landfill gas, since there is a recognised interaction between the two. Where a gas utilisation scheme is in place and leachate levels are high, an effective leachate extraction system may increase gas yields. And the potential for re-circulation of the leachate within the landfill mass as part of a progressive management system may create further opportunities for an increase in gas production.
It is therefore highly beneficial to approach landfill environmental management in a coordinated way, considering the tasks of leachate extraction and treatment along with gas management and a clear understanding of the other elements of the landfill management process in the site.
Leachate extraction is an integral part of Biogas Technologys unrivalled capability in landfill environmental management. We have earned a reputation for innovation in the application of technology and for excellence in the quality of service we offer our clients.
Our success is built on providing single-source accountability to our clients whatever the range of services being supplied - from fieldwork, through integrated gas and leachate management, to gas utilisation and power generation schemes. We offer clients guaranteed solutions to the specific problems and opportunities presented by each individual site and back this up with a commitment to providing comprehensive after sales support.
