Natural & Forced Evaporation

Product Description:

The process of evaporation by ponds has been used for quite some time in wastewater treatment. The idea consists of depositing wastewater in large open ponds allowing water to evaporate through solar radiation and wind, leaving a pond of concentrated residual waste for treatment.

Despite their simplicity, evaporation ponds can be very useful in obtaining zero liquid discharge in salt rejection and other effluents of mineral composition since no effluent is discharged directly into the natural environment.

As previously mentioned, evaporation ponds are artificial ponds with very large surface areas that can contain potentially hazardous waste. Their purpose is to reduce the water contents of different solutions by “natural” evaporation. Thanks to such treatment, the volume of waste requiring treatment is lowered, thus achieving a reduction in costs while obtaining an increase in the concentration of materials (or products) that have commercial use.
