R o discharge TDS

[Rigfisher]

My TDS going into my RO system is 108 my TDS coming out is 5 is that good or bad?

(108-5)/108*100 = 95.4% rejection. That's pretty normal.

 

[Misled]

Yep that's normal. A DI will take out the rest.

 

[Dr. Reef]

that is normal but run the output through DI and it will be down to 0
