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.

Abstract: A freely swinging self-levelling spray boom includes a support structure and a mounting adapted to mount the support structure to a vehicle to swing freely about a pivot axis lying in a direction of travel of the vehicle. A spray boom is supported by the support structure. A tank adapted to hold liquid spray medium is supported by the support structure. The tank is symmetrically mounted to the support structure relative to the pivot axis. The weight provided by the tank and the liquid spray medium it contains serves to maintain the support structure and the spray boom in a substantially horizontal orientation when the vehicle is traversing a slope and dampen oscillations of the spray boom.

Abstract: Coverings, canopies, or housing each having a removable bottom wall which collectively substantially encapsulates each drive chain of an irrigation mover is disclosed, which prevent or substantially alleviate drive chain link corrosion and which statically extend fore and aft of an engine of the irrigation mover along the frame thereof.

Abstract: A device for increasing the evaporation of liquid from mud pits is disclosed having an elongated collection tank suspended from flotation means for holding a quantity of the liquid. A plurality of riser pipes extending from the collection tank to the surface of the liquid, each of the riser pipes having a nozzle connected to the end thereof capable of converting the liquid into a hollow, conical spray having ultrafine droplets.
