CLLEEN Landfill Leachate

Solving landfill leachate problems with CLLEEN LEACHATE

If any one aspect of a landfill is assured, it is that eventually it is going to leak.  And that landfill leachateleachate pond, CLLEEN Water and Power, is going to need treatment before it is reintroduced into the environment.

CLLEEN Water and Power offers CLLEEN LEACHATE (Leachate Evaporation) to solve your leachate problem.

The CLLEEN VAP Crystallizer (evaporator) is built in modules of 25 GPM each, so it can treat any flowrate, and at the TDS levels of the leachate, will do so using less than 10 kWh/250 gallons, which is 1/20th the energy usage of any comparable industrial evaporator.

CLLEEN LEACHATE is similar to the treatment we use with existing customers for the CLLEEN VAP mobile units in the oil and gas exploration and production fields, to evaporate produced and flowback waters of hydraulic fracturing operations. The CLLEEN LEACHATE system will work equally well for landfill leachate.

It will provide simpler operation and maintenance, use less energy, and be a more environmentally-friendly solution that other leachate treatment options.

CLLEEN Water and Power ensures that the CLLEEN LEACHATE system receives air quality and all other permit exemptions to be present at a landfill. This means no additional permitting is necessary, as CLLEEN addresses the two items of most concern to the state and Federal environmental agencies:

air quality (CLLEEN has a granular activated carbon (GAC) filter) on the vapor exhaust to capture VOCs


secondary containment, to impound water leaks and spills during connection/disconnection and water transfer.

Since CLLEEN’s GAC filters are proprietary and customized for each application, CLLEEN provides you with a GAC filter that will capture ammonia vapor and other volatiles of concern in your leachate water chemistry.

The only consumable on the CLLEEN LEACHATE is the activated carbon in the GAC filter, so you will evaporate all the leachate water, and have only dry salts to landfill, as well as spent activated carbon.


What the customer provides:

1.  Shipping/transporation costs to the site.
2.  The power: 480V/60Hz/3phase AC power of at least 15 amps.
3.  Pumping (with an 18-mesh screen or higher to limit TSS diameters to under 1mm) from the leachate source to our skid-mounted brine pump on the CLLEEN™ LEACHATE unit.
4.  Secondary containment to capture the dry salts from the evaporation chamber discharge.
5.  Dry salts and activated carbon disposal.
6.  Air quality monitoring to ensure ammonia vapor levels are below 10 ppm.

CLLEEN systems can also recycle and reuse the water if you have irrigation or grey water, or even potable water applications.  In these cases, the system would be a customized CLLEEN MSF Distillation and CLLEEN LEACHATE solution for you.

A few landfill leachate statistics…LandfillLiner, CLLEEN Water and Power solutions,

The barriers of all landfills will eventually break down and leak leachate into ground and surface water. Plastics are not inert, and many landfill liners and plastic pipes allow chemicals and gases to pass through while still intact.16

In 2008, a survey of landfills found that 82 percent of surveyed landfill cells had leaks, while 41 percent had a leak larger than 1 square foot.16

Newer, lined landfills leak in narrow plumes, making leaks only detectable if they reach landfill monitoring wells. Both old and new landfills are usually located near large bodies of water, making detection of leaks and their cleanup difficult.16

“First, even the best liner and leachate collection system will ultimately fail due to natural deterioration, and recent improvements in MSWLF containment technologies suggest that releases may be delayed by many decades at some landfills. For this reason, the Agency is concerned that while corrective action may have already been triggered at many facilities, 30 years may be insufficient to detect releases at other landfills.” Source: US EPA Federal Register, Aug 30, 1988, Vol.53, No.168


“82% of surveyed landfill cells had leaks while 41% had a leak area of more than 1 square feet,” according to Leak Location Services, Inc. (LLSI) website (March 15, 2000).
