Hello Aquablu Lanka, Thanks. Evaporating such a high volume of water requires a huge amount of energy and is not really sustainable even when using solar energy. Instead I would recommend to first concentrate the KNO3 using NF/RO membranes as to recover clean water for reuse and then evaporate the RO concentrate with the KNO3. Regards, Bruno
