What is difference between RO and DM plant

Question

Accepted Answer

RO and DM plants are both used for water treatment, but they differ in the process and level of purification.

RO (Reverse Osmosis) plant uses a semi-permeable membrane to remove impurities and contaminants from water.
DM (Demineralization) plant uses ion exchange resins to remove mineral salts and impurities from water.
RO plant is more effective in removing dissolved solids, while DM plant is better at removing mineral salts.
RO plant is commonly used for desalination and producing drinking water, while DM plant is used for industrial applications.
RO plant requires higher pressure for operation compared to DM plant.

Accepted Answer

Reverse Osmosis (RO) is used to partially clean-up tap water to make it roughly 90% to 99% pure. Deionization (DI) filters exchange positive hydrogen and negative hydroxyl molecules for positive and negative contaminant molecules in water. DI filtering and other processes are sometimes referred to as "water polishing."
