| 31. | The accumulated leachate is periodically removed, or used in summer to suppress dust on the landfill.
|
| 32. | The leachate is subjected to one of several sequences of precipitation, solvent extraction, and ion exchange.
|
| 33. | Water-borne bacteria digest organic material in leachate, but use up much of the available oxygen.
|
| 34. | The aerobic environment decomposition is accelerated and amount of VOCs, toxicity of leachate and methane are minimised.
|
| 35. | Thus, less time and energy is required to process the leachate, making the process more efficient.
|
| 36. | A number of technologies, including clay and plastic liners were used to contain the smell and leachate.
|
| 37. | The solution ( leachate ) was then removed from the ore and the valuable metals extracted using activated carbon.
|
| 38. | This landfill, and others along the Raritan River, provide an ample supply of leachate to the waterways.
|
| 39. | The pipes also serve as drains within the drainage layer to minimize the mounding of leachate in the layer.
|
| 40. | All three mechanisms involve the reintroduction of collected leachate supplemented with water to maintain moisture levels in the landfill.
