  2. Leachate - Wikipedia

    en.wikipedia.org/wiki/Leachate

    The most common method of handling collected leachate is on-site treatment. When treating leachate on-site, the leachate is pumped from the sump into the treatment tanks. The leachate may then be mixed with chemical reagents to modify the pH and to coagulate and settle solids and to reduce the concentration of hazardous matter.

    en.wikipedia.org/wiki/Landfill_liner

    The final cover functions as a way to keep the water out of the contaminate and to control the runoff from entering the system. This helps prevent plants and animals from being harmed by the waste contaminated water, leachate. Using gravity and pumps the leachate is able to be pushed to a sump where it is removed by a

    en.wikipedia.org/wiki/Toxicity_characteristic...

    If TCLP analytical results are below the TCLP D-list maximum contamination levels (MCLs) the waste can be accepted. If they are above these levels the waste must be taken to a hazardous waste disposal facility and the cost of disposal may increase from about $50.00/ton to as much as $1200.00/ton.

    en.wikipedia.org/wiki/Ash_pond

    Wet disposal has been preferred due to economic reasons, but increasing environmental concerns regarding leachate from ponds has decreased the popularity of wet disposal. [9] The wet method consists of constructing a large "pond" and filling it with fly ash slurry, allowing the water to drain and evaporate from the fly ash over time. [10]

    Haywood County's plan to address both ground water and air contamination found at the Francis Farm landfill changed through the years. Upon learning leachate from the unlined landfill had reached ...

    en.wikipedia.org/wiki/Forward_osmosis

    This approach has been used, for instance, in the treatment of landfill leachate. An FO membrane separation is used to draw water from the leachate feed into a saline (NaCl) brine. The diluted brine is then passed through a RO process to produce fresh water and a reusable brine concentrate.

    On-site leachate and surface water was contaminated by heavy metals, PCBs, and VOCs including toluene and xylene. Leachate, surface water and slough water was contaminated by multiply resistant pathogens. [78] July 29, 1991: April 25, 1995

  9. In situ leach - Wikipedia

    en.wikipedia.org/wiki/In_situ_leach

    Phase 1: Pumping of contaminated water: the injection of the leaching solution is stopped and the contaminated liquid is pumped from the leaching zone. Subsequently, clean groundwater flows in from outside of the leaching zone. Phase 2: as 1, but with treatment of the pumped liquid (by reverse osmosis) and re-injection into the former leaching ...
