RODI question

Ok so I've got a couple chambers in my rodi unit that say "taste and odor removal" could I remove these and just run the RO and DI?

Thanks.

 

Yes, those are usually little throw away granular carbon filters used for drinking water systems. For our uses they are not good since they actually add TDS back to the water due to the carbon breaking down. GAC has a very short useful life too and they probably only last 100 gallons or so anyway, even in a drinking water system.

 

Cool! I'll go ahead and remove them. I won't have a micron filter, is that ok?

 

Not sure what you man by a micron filter?
At a minimum you should have in this order a sediment filter, a carbon block filter, the RO membrane and a DI filter. Some systems will have two or more little horizontal DI filters in place of a single 10" vertical 20 oz DI filter but although less efficient they function basically the same. You may also find some sysems which still use the old outdated method of using two less efficient carbon blocks or even cheap granular activated carbon in front of the RO membrane versus a single low micron high efficiency carbon block. This is often the case when that use a high micron sediment filter and they rely on the carbon block to act as a secondary sediment filter to trap what the sediment filter misses. This is not a good isea since carbon is made up of billions of tiny pores where the chlorine is adsorbed, plug of foul the pores with sediment and its useless for treating chlorine and your membrane is soon toast.

 

I ment the sediment filter. The sediment filter might be built into one of the taste/odor removal filters. If that's the case can I still remove them and just run the RO and DI with no carbon or sediment pre filter?

 

If you dont have a sediment and carbon block before the ro/di the ro will not last long, then the same with the DI. At least I think that is the case.

 

Taste and odor filters always follow the RO membrane, never before. You should have a sediment and carbon block filter before the RO membrane to protect the membrane which in turn protects the DI resin.
