Description

Evaporation is an essential part of the water cycle. The sun (solar energy) causes evaporation from the oceans, lakes, moisture in the soil, and other sources of water. The evaporation of water occurs when the liquid surface is exposed, allowing the molecules in excess of escape and to form water vapor.

Evaporation ponds produce salt from seawater. They are also used for the disposal of brine from desalination plants. Mines use evaporating to separate minerals from the water basins. Evaporation ponds are used by contaminated sites to remove water from hazardous waste, reducing the weight and volume so allowing the toxic sludge to be more easily transported, processed and stored. Evaporation ponds are used to prevent pesticides, fertilizers and salts from agricultural wastewater to contaminate the streams in which should be flowing.

With 25 years of experience in the production of water mist systems, EMI has developed an evaporative floating machine structurally simple, suitable for use in any environment thanks to the materials with which is manufactured, and the very low energy consumption. The E46 is as an effective solution to increase at least 10-12 times the evaporation that would normally occur on the same free surface area. The atomisation of water takes place by pumping the water through special nozzles designed to exploit the Venturi effect to also suck air in such a way to have the formation of drops with high capacity of evaporation. The nozzles are also designed to minimize the effect of drift of the sprayed water to remedy its dispersion in case of wind, in this manner everything that is not evaporated falls in the vicinity of the machine avoiding contamination of areas outside of the basin.

Example

A basin with the following dimensions (100 m length x 30 m width x 1 m depth) contains 3,000 m³ of water. In sunshine 3 m³ evaporates per hour with the help of our E46 (makes 1 mm of water).

Result:
In one day with 10 hours of sunshine, approx. 50 m³ evaporates ((3 m³ x 10) + (1.4 m³ x 14)); this results in 16.67 mm per day.
