  • Modular floating water evaporation system
    Patent number: 7604710
    Abstract: A floating water evaporation system for use in disposing of excess water from oil and gas drilling operations is provided. One or more nozzle arrays float on the surface of a wastewater pond a distance away from the pond shoreline. Each nozzle array includes a series of upright risers that extend above a water reservoir tank. Spray nozzles are mounted on each riser. The water reservoir tank is mounted between floating pontoons that elevate the nozzles a distance above the surface of the pond. Water from the pond is pumped through the nozzles to create a patterned spray of small evaporable droplets.
