A multidisciplinary group of the Polytechnic University of Cartagena (UPCT), led by Francisco Vera and in which experts have participated in hydraulics, renewable energies and machines and thermal engines, has carried out a study of the system of evaporation and elimination of brackish water of the company COBET-Tratamiento del Agua SL
Researchers have evaluated the operation of the EVACOLD brine evaporator prototype in different meteorological conditions, characterizing its energy consumption and proposing improvements to increase its performance and applicability.
The system uses a fan for the air to absorb and evaporate the water and is designed to solve the problem of the concentrated nitrate water generated by the desalination plants, which has caused that all those in the Cartagena field have been closed, except for the Tomás Ferro Agroalimentary Experimental Station of the UPCT, in which the tests have been carried out and which has the permission of the Hydrographic Confederation to have a deposit to manage the brine without environmental risk.
The industrial equipment studied by the UPCT experts is also applicable to various industries that generate liquid waste.
Researchers believe that with a future model E-2000 improved "could evaporate up to 2,000 liters per hour at a reduced cost if you have renewable energy and / or waste heat, for example cogeneration plants or biomass boilers", explains Vera
Researchers have used the equipment for the experimental treatment with brine that the Chair of Sustainable Agriculture of the UPCT has in the deputation of La Palma, which is also coordinating other trials to find technological solutions to the problem of brine in the Campo de Cartagena .
