DriBoss® Wastewater Evaporation Solutions
There are two primary choices for evaporation systems: land-based vs. floating systems and water-fracturing or atomized mist.
These evaporators are located on dry ground, along with the pump system, allowing easy maintenance and service. Land-based units may require repositioning (or automation) if wind direction varies greatly or if the site is sensitive to spray drift.
Mounted on pontoons, floating units are located directly in the wastewater pond, typically with a submersible pump. Because of their lighter weight, water fracturing designs are typically specified for floating applications.
Fracturing is essentially splitting the droplets with a high-speed fan and propelling them into the air. The technique is well suited to smaller areas, especially those in which the wastewater contains high solids levels or large particulates. Large water-fracturing evaporators can operate in a vertical or horizontal position (to minimize water droplet spray drift during winds) and can be used on small ponds or large lakes. These units are well suited for use with dirty water and in treating acidic water.

4) ATOMIZED MIST
Atomization employs specialized nozzles to create droplets of a controlled size, then uses a powerful fan to compress the air through a tapered barrel and propel the mist over a large area. Atomized mist designs are more mobile, but are not effective on water with large undissolved particulates. This type of design is best for larger operations and greater volumes of wastewater, where lower amounts of dissolved solids are present and particulates are small. The larger size and weight of atomized mist designs typically dictate that they be located on land.
A key advantage of this type of unit is the ability to operate effectively in windy conditions, since it uses a high powered fan to blow the water droplets into the air. A potential disadvantage to this type of evaporator is that it throws the water droplets quite far (30-70 meters, depending upon the model size).
Land-based water-fracturing evaporator vs. Land-based atomized mist evaporator
The large model evaporators require a water supply of 70 gallons per minute (265 lpm) at 100 psi (7 bar). Pump stations are available for the land-based units. Our equipment has been designed for industrial durability in harsh conditions and is supplied as self-contained units, ready to install. We use stainless steel construction to minimize corrosion, and offer both self-priming and self-feeding pump stations (see examples below). Self-feeding pumps are a better fit with fully automatic systems, since drainage is complete when the system is shut down.
