Evaporate tailing ponds or volatile waste
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. Spray nozzles create droplets of water which increases the surface area exposed by several orders of magnitude.
This water can easily be sprayed through a nozzle to promote quicker evaporation. This is effective because it creates water droplets that increase surface area to catalyze evaporation, simultaneously dispersing the droplets to expose them to the wind.
As the water to be disposed of contains some solids or wastes and is unclean, selection of the nozzle with regard to clog resistance is important. BETE is the original developer of the spiral design that surpasses other nozzles in accommodating liquids without clogging.
Selecting an Evaporative Disposal Nozzle:
The BETE TF series spiral nozzle line produces sprays composed of droplets 30-50% smaller than conventional designs at equivalent pressures. This finely atomized spray creates an extraordinarily large amount of droplet surface area over which evaporation can occur. The nozzles are a compact, rugged, one-piece design; having no internal plates or disks.
The BETE TFXP series are superb performers with the 90° spray angle the preferred choice. The TF32XPN nozzle offers a good compromise between drop size, clog resistance, and price. If the solids are fine, the smaller orifice of the TF-12-XPN provides a smaller droplet size to improve evaporation and is also the smallest nozzle size recommended. Your location's wind speed is a major factor in determining which nozzle is best. Our experienced engineers can help determine which nozzle will perform as required with your design details.
The standard materials used to make our nozzles suitable for evaporative disposal are Brass, 316 Stainless Steel, and cobalt alloy 6. Other materials are also available.
