The best way to dispose of certain types of wastewater can be to get it up in the air and evaporate it. Air assisted rotary atomizers get more air mixed with more water for higher evaporation rates with lower energy use.

Ideal for:

• wastewater evaporation
• water fracturing
• mine water removal
• Food process water
• Industrial process water
• CBM water
• oil and gas wastewater
• drillwater & drill mud
• other dewatering

Let’s start with the basics on what makes a good wastewater evaporation process work:

Advantages:

• Atomizer highly resistant to wear & clogging.
• sprays mud and suspended particulates including drill mud
• Resistant to salts, lime, and dissolved solids
• encrusted parts can be cleaned and reused

• The amount of surface area you make from each gallon of water matters. The smaller the droplets the more surface area you get out of the water. The more surface area, the faster the evaporation. The smaller the droplets, also the slower they fall back to earth. More time suspended means more time to evaporate.
• The amount of air you can mix with the water matters. Great air mixing is CRITICAL! You can only evaporate enough water to saturate the air. No matter how fine the drops or how high you spray them, if the air saturates with humidity, you’re done evaporating. A high volume airflow that is highly turbulent to mix with and entrain surrounding air will significantly increase your evaporation rates.
• How many gallons per minute you can remove matters. If you have 20 million gallons of water to evaporate, what good is an evaporator that can do 10 or 12 gallons per minute? The array at right is shown atomizing approximately 64 gallons per minute. Current improvements allow it to reach over 80 GPM.

Which atomizer is right for the job?

For high volume, high dissolved solids applications:

• Proptec PT100 Air-assisted and guarded hydraulic drive atomizer

For smaller jobs:

• Penguin PT200 electric atomizer with or without air assist

Typical atomizer configuration: For raw atomizing and air power, with the most rugged durability, our PT100 Air-assisted and guarded, hydraulic drive atomizers (shown at left) are generally indicated. With a maximum airflow of 10,000 CFM (300 cmm) of highly turbulent air, and a maximum water capacity of 6 gallons per minute, each atomizer is capable of spraying over 8500 gallons (33,000 liters) per day.

An array of PT100 atomizers can make quick work of your wastewater. A 1 million gallon pond (1 acre, 3’ deep) could be evaporated in as little as 1 month with a 4 atomizer array, or 2 weeks with 8 atomizers.
