Evaporative Disposal Nozzles

Increase evaporation rates in holding, tailing, or other waste water ponds


Many industries produce excess water which contains solid particulates. These particulates must be disposed of in a responsible way. Separation of the particles from the water is often accomplished by placing the water in ponds where the sun is employed to evaporate the water. The solid particles can then be recovered and processed. As evaporation can only take place from the surface of the pond, operators are forced to either wait a long time for the water to evaporate or make very large ponds to increase the surface area. An alternate and effective way to accomplish the same goal is to use nozzles to spray the water into the air. By spraying and atomizing the water from the holding ponds into the air, spray nozzles significantly increase the surface area of water exposed to the air, thus improving the evaporation efficiency and decreasing the area needed for the pond.
 

Selecting an Evaporative Disposal Nozzle:

Important factors to consider:

  • Environment
    • Average temperatures, relative humidity, prevailing wind speed and direction, etc.
  • Nozzle placement
    • In general, spray nozzles are placed evenly around/over the pond at a height that maximizes residence times while taking droplet drift due to wind into account
  • Nozzle clog resistance
    • As the water to be disposed of often contains solids or waste particles, selection of the nozzle with regard to clog resistance is important
  • Available flow rates
  • Required evaporation rates
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
    • Typical operating pressures range from 10-20 psi (0.7-1.4 bar) to produce a drop size capable of efficient cooling while minimizing evaporation losses and wind drift
  • Our experienced engineers can help determine which nozzle will perform as required with your design details

Common Evaporative Disposal Nozzle Uses and Industries:

TFXP

  • The extended spiral design of the TFXP series of nozzles provides unparalleled clog resistance
  • Largest free passage possible in a spiral nozzle - passes particles equal to the orifice size
  • Clog resistant
Nozzle Type(s):
Spiral
  • Spiral nozzles provide some of the finest atomization of any nozzle type for medium to high flow rate applications (producing sprays composed of droplets 30-50% smaller than conventional designs at equivalent pressures), creating an extraordinarily large amount of droplet surface area over which evaporation can occur and making them ideal for evaporative disposal applications
  • Spiral nozzles are a compact, rugged, one-piece design- having no internal vanes or components.
