Treatment of salty waters and brine effluents with a high potential for recovering salts and generating new freshwater resources
Developed by Cobet Tratamientos del Agua S.L.
EVACOLD uses the residual heat generated in steam boilers of chimneys or the energy generated by renewable infraestructures, to evaporate salty waters at temperatures below 50 ºC. Salts are concentrated for being treated or reused, while water vapour can be condensed to collect new water resources. In semiarid areas with brackish water resources, EVACOLD emerges as an energy low-cost solution able to treat the brine effluents resulting from osmosis desalinization plants.
See more information about this level and the TRL and SRL levels.
EVACOLD heats incoming brackish (polluted) water to 50 °C and passes through an exchanger in which it is in contact with an incoming pre-heated air flow. The system generates two by-products: an air saturated with water, which can be condensed to generate distilled water, and dry salty residue that need to be handled properly. The energy required by EVACOLD to heat both incoming fluids (brackish water and air) is provided by: a) a photovoltaic solar panel which feeds a fan, the air cooling system and a set of small transfer pumps, and b) solar thermal panels which heat the incoming water to 50 °C, and the air up to the saturation point. In EVACOLD, there is no change between the liquid and vapor phases, so the energy consumption is minimal.
Limitations/conditions under which this innovation does not work or is less effective
EVACOLD generates a dry salty residue that has to be managed by an authorized residues manager
Added value
EVACOLD contributes to improving the management of salty water or salty effluents derived from the purging of boilers, the olive industry, salting or the salt industry. It reduces the volume of polluted effluents and eases their transport and handling. The cost of evaporation through EVACOLD technology has been estimated 15 times less than traditional or current technologies. In the agricultural sector, EVACOLD is able to reduce the brine effluents resulting from desalination plants by osmosis and increase the chances of nutrient recovery (nitrates). New water resources suitable for irrigation can be recovered if a saturated air cooling system is coupled to the system. EVACOLD is more economical to build, assemble and maintain than other conventional systems. The standard system is 20000 lts/day and can be nested installed everywhere. This standard is ideal for medium volumes of discharges that currently do not have where to legally pour as well as olive pickles.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.
