Question

Difference between ro plant and dm plant

Answer 1

RO water is water created by passing raw feed water though a membrane/s which removes ionic and several non-ionic (organic and suspended) compounds using high pressure to force water molicules through an osmotic membrane creating an ion rich stream on the feed side of the membrane and a more pure from ion stream on the product side of the membrane.

DM water is created by passing raw water though demineralization beds (usually two .. one designed to remove the positively charged ions .. cations .. which then leads to a second bed designed to remove the negative charged ions .. anions. It will have less "slippage" of ions than RO units creating a higher purity water.
