<p>A method for increasing the evaporation rate of an evaporative pond comprising a pond liquor comprising water and at least 1% by weight of sodium carbonate, said evaporative pond being in contact with an ambient air at an ambient air temperature of more than 0°C, the method comprising the following steps:
- feeding part of the pond liquor to a heat exchanger,
- heating the pond liquor in the heat exchanger with heat and producing a heated pond liquor,
- feeding the heated pond liquor into a spraying device at a temperature called hereafter 'operating temperature' of at least 10°C, preferably at least 15°C, more preferably at least 20°C above the ambient air temperature,
- spraying the heated pond liquor into an open area of the evaporative pond with the spraying device, so that to evaporate at least part of the water of the pond liquor when sprayed.
