Abstract
A groundwater remediation system includes a capillary media supported and positioned such that it is partially submerged into a groundwater source to be remediated. Groundwater is drawn into the submerged portion of the capillary media and further into the non-submerged portion of the capillary material via natural capillary action. As the water evaporates from the non-submerged portion of the capillary media, the dissolved solids within the water precipitate onto the media leaving the precipitated solids for reclamation or disposal and allowing the cleaned water vapor to disperse into the ambient air. In some embodiments, heat may be added to the media, water, or air to accelerate the evaporative process.
Claims14
A system for groundwater remediation, comprising:
- a capillary media configured to absorb water and propagate the water from a first portion of the media to a second portion of the media via capillary action;
- a support structure for supporting the capillary media within a contaminated water source such that the capillary media is partially submerged and partially exposed so that contaminated water is drawn upwardly through the capillary media via capillary action to precipitate soluble materials from the contaminated water onto the capillary media upon evaporation of the water from the exposed portion of the capillary media;
- an air source permitting air to circulate around the capillary media to facilitate evaporation of water from the exposed portion of the capillary media;
- and
- a heat source operable to heat the capillary media, the contaminated water, the air, and combinations thereof, wherein the heat source comprises a microwave heater comprising a magnetron microwave emitter configured to generate microwaves.
