Office lost power and now I’m still without water. Cant make rodi even if I wanted to... Can’t boil water if you don’t have any...
Lol just curious how are you running your filtration setup. What are the 2 pressure reading canisters? Presumable the 2 canidters next to the RO Unit are DI.
I assume that you have an RO membrane after the carbons and before the DI? What rating (gpd) do you use?
1. 0.35 Pleated
2. 0.2 Zeta
3 Carbon Block
4 Carbon Block
6. Chloramine block
7. Mega DI A
8. Mega DI B
9. Silica Buster
10. Enduro DI A
11. Enduro DI B
Did get that right? That’s a lot of stages. Also, as a side question, why would one prefer a carbon block vs straight GAC?
I don’t think it’s a problem. They can handle higher pressure than that. A permeate pump puts out 100psi
The carbon(s) always go before the membrane since, in addition to it being toxic to our tank inhabitants, chlorine will significantly shorten the life of the membrane (as will sediment). Some of the carbon/chloramine blocks I’ve used say they are GAC, while others don’t specify. I suspect that the size of the media and the way it is packed in is what makes it a “block” as opposed to, say, a refillable GAC canister. In any case, it sounds like you’ve got a good system4. Chloramine
I will probably add a 3rd canister for chloramine before membrane. BRS has a ‘Chloramine monster’ that will allow me to never worry about chlorine, which is again overkill. I’m most concerned with carbon stage because it’s the easiest to overlook. There’s no way to see the depletion visually, which means you need to look at that TDS meter regularly. I don’t rely on just the TDS meter for carbon stage, I have to use chlorine strips every now and then.
Carbon blocks- I get to choose which are high capacity, microns, and chloramine. Idk if you can do that with GAC. Never used it.
