What is the result of sending de-mineralized water to a reverse osmosis skid?

Sending de-mineralized water to a reverse osmosis skid leads to a reduction of total dissolved solids (TDS) to acceptable levels. De-mineralized water has had many of its minerals and impurities removed; however, the reverse osmosis process further purifies the water by allowing it to pass through a semi-permeable membrane that blocks larger particles and impurities, effectively lowering TDS.

This advance in purification can significantly enhance water quality, making it suitable for various applications where high purity is essential, such as in the food and beverage industry, pharmaceuticals, or industrial processes. The other options, while they may reflect different properties of water processes, do not directly pertain to the immediate effects of reverse osmosis on de-mineralized water.
