No. Steam distillation super heats the water to eliminate all minerals within a tolerance of 0-1 (or perhaps 0-2 ppm TDS), recollects the steam, and condenses it back into a liquid form. Reverse osmosis sends water through membrane filtration and other treatments to produce purified water. The TDS of reverse osmosis water varies widely from close to 0 to up to 50 or more. Kandiyohi has a TDS of 22-27 due to the minerals that are added after purification to enhance flavor and health benefits.
