Difference between a complete D.M. plant and a mixed bed only

Can I obtain purified water for pharma use by providing a single mixed bed only or will I have to purchase a complete set of D.M. water plant consisting of cation bed, anion bed followed by a mixed bed? Please suggest.

Thanks

Dear Mr. Gupta,

It all depends on the purity of water you need and the impurity level of water(raw water) which you want to make pure.

First analyse your raw water, then prepare 1. raw water analysis report 2. specification of water that has to be used in your pharma industry,
consult an expert in water treatment.

What quality of Phara grade water do you require?
PW, WFI, Potable Water.

Generally if your water is clear and having less TDS value, Go for softener, RO, MB with UV treatment.

It's recommended to first analyse the water quality and then decide scheme
