RO is by far the best solution, most common, prooven, easy to operate & mainten. Treat 50% of water through RO and blend 50% untreated water to achieve target values. Alternately Nano Filtration can also be explored which will reduce the operating cost. Since the multi-valent ions are in considerable amount, NF will reduce TDS to desired extent. (however this will be for 100% capacity)
