Leachate at landfills changes over time.
Leachate treatment facilities are a key element of any landfill design. The treatment of the liquids generated through the process and life of a landfill are necessary for many locations before discharge. In addition, when researching methods for treating liquids, involve experts in the analysis of the waste to evaluate and determine the correct treatment.
The determining method gets based on the leachate’s current make-up and the result required by the receiving party. These specialists will typically begin with a pilot study to develop a basis of design. This pilot study will generally look at the needs for today and project what the future needs might be in the years to come, knowing both the volume and make-up will change.
For example, this information helps select a process equipment supplier. Add your design-build team immediately following for them to:
- Work together to develop the design for the facility
- Factoring in the equipment
- And durability for the application
The quantities of liquid also need to be understood to size the system. Also, the tanks needed to store the untreated and treated liquid before treatment or discharge. All factors will help determine the amount of space required to construct the plant. The team tasked to work on this project will need to account for some key factors including the location, interior features, building design, and safety.
The location of the new facility is key. For example, it needs to get placed where the leachate lines can come together and also for easy access to the discharge line. The leachate treatment facility must be located in an area where future landfill cells are not affected and where there is enough ground area to accommodate the future growth and expansion of the system.
