Evaporation Ponds

Evaporation ponds use solar energy to evaporate produced water. After a large portion of the original water volume evaporates, the remaining concentrated salt sludge is either left in place or removed and hauled offsite for disposal. Depending on produced water quality and other regulatory criteria, the ponds may require liners, or constructed on natural geologic confining layers to prevent infiltration of the water to the aquifer. To maximize the evaporation rate, 

Evaporation ponds must be covered with netting or other deterrents to limit waterfowl and other species from coming into contact with contaminants in produced water.

Evaporation ponds are most viable in relatively warm, dry climates with high evaporation rates, level terrain, and available and inexpensive land.

Application

Evaporation ponds are used in many applications where clients wish to separate liquid from solids. For hazardous waste these ponds are designed to remove water from the waste to allow for economical transportation of the waste to a treatment facility. They can also be used to separate water from salt to allow for easy harvesting.

Advantages

• Salt drift and dry aerosol particles are kept in the boundaries of the operation area

• Airflow and water flow control provides maximum protection against pollution drift

• Droplet size and airspeed control allowing reducing pollution plume

• Down draft configuration keeps lofted aerosols to a minimum allowing operation over a wide range of environmental conditions without the pollution drift.

• No chemicals required.

• Energy use : The only energy requirement is pumping concentrate to the pond and in
  certain circumstances aeration for enhanced evaporation.
