Nuts, that is an excellent point. I am failing to find the outflow concentration of salt, but you are correct that the output is likely to be only mildly concentrated (eg 7% salt). For all I know, it take an order of magnitude more energy to emit pure salt rather than a brine. Total amount of salt is not insurmountable, but the volume of output would be challenging quickly without enormous evaporation pools.
