Concept of Leachate
Leachate is described as a polluted liquid effluent that has seeped through the bulk of garbage dumped in a landfill, the features of which and the pollutant load of which are, in most situations, unexpected, highly changeable, and extremely hazardous to the environment.
How is leachate generated?
Leachate is a mineral-organic combination generated when water infiltrates the waste pile. This water can be derived from rain, snowfall, irrigation water, subsurface water penetration, runoff water, waste inherent humidity, and liquid trash placed in the landfill with solid garbage.
Water circulates through the waste material, removing and dissolving contaminants while also functioning as a medium for numerous chemical processes and biological degradation of these pollutants.Gravity promotes water mobility, thus it infiltrates from the waste mass's outermost layers to the waste mass's lowermost layers.
Under typical working circumstances, leachate is drained from the lowest portion of the waste mass by building an impermeable layer and a network of leachate collecting pipes and channels, which must be directed to a place of storage and later treatment.
What happens if leachate is not treated?
If the leachate is not properly handled, the landfill from which it originates can become a highly serious source of hydrogeological pollution, due to the possibility of leachate penetration into the soil, surface, and groundwater.
What are the Leachate control and collection processes?
Organic and inorganic chemicals dissolve and increase the pollutant load of the leachate as it develops and circulates through the waste material.
In theory, this is a positive effect since it liberates the waste mass from these contaminants, which would otherwise stay immobile and develop in the solid, potentially leading to future pollution problems and expenses connected with their treatment.
Leachates are a serious source of pollution of soils, surface water, and groundwater if not appropriately managed. In addition to contaminating the environment, leachates have a strong odour (particularly young ones), thus they must be handled and transported properly.
Following are the most critical considerations for effective leachate management:
- The landfill design must be correct and robust.
- There must be control and reduction of harmful liquids entering the landfill waste bulk.
- Installation and operation of a system for leachate extraction, collection, and transfer to treatment facilities should be there.
- Installation and maintenance of a particularly built leachate treatment facility should be there.
Following control measurements must be used-
- Determine the best placement for the landfill.
- Dumping restrictions prevent the introduction of liquid waste into landfills.
- Use suitable landfill operating procedures.
- Use runoff water management measures.
- Set up leachate collection and transportation systems.
- Choose, design, and install an appropriate leachate treatment system.
- The kind of treatment, its design, installation, and operation are determined by the features of the landfill, because the leachate will have varied characteristics that necessitate the use of distinct procedures and technologies for its treatment based on these variants.
Now, consider the following characteristics!
- The landfill's size, age, and potential future expansions.
- The kind of the waste that is collected, as well as its moisture content.
- Rainfall and temperature regimes are characteristics of a climate zone.
- Regulations and discharge legislation applicable to the area.
- Dumping into a body of water or the sanitation network is an option.
- Configuration of amenities and land availability.
- A budget is available.
