FIELD: agriculture.

SUBSTANCE: evaporation pond of the mineralised drainage effluent is coupled by water regulating facilities 2, 3 with the supplying channel 1 and is provided with floating evaporating elements of hydrophilic capillary-porous material. The floating evaporating elements are made in the form of hollow perforated drums 12 coated with hydrophilic capillary-porous material, mounted between two support floats 9, 10 with the ability to rotate around its horizontal axis by means of the end semiaxes inserted into the sleeves placed along the length of the floats. The drums 12 are provided with the mechanism of their synchronous rotation by 180° and back.
