RO/DI Filter Replacement

[Buckeye Hydro]

A sediment filter will catch some iron - specifically the ferric iron - Ferric iron is out of solution - not dissolved. The ferrous iron in your water is in solution. The water turbulence at the surface of the sediment filter will oxidize some of the ferrous iron and encourage it to come out of solution. But any ferrous iron that stays in solution will not be caught by the sediment filter.

Do you have a water softener? A water softener will remove low levels of iron.

Realize that if you still have iron in the water when it hits the membrane, the membrane will eventually foul/load up with iron.

That pump is made in Asia. Is the pressure adjustable? If so, and assuming you have it mounted AFTER your last prefilter, yes, turn it up to 80.

You might try two sediment filters and a 5 micron carbon block

I tested the output water tonight and it is down to 11 after the filter change. That was a pleasant surprise. Figures out to be 97% How do you degas the water if I have too? right now I have my output water going to a 3 gallon pressure holding tank.
thanks

To degass the water you will have to have a holding tank with an air pump and air stone then pump that water through the di stage. Im not sure how long you have to degass the water for though before its safe for the di.

I should also state you shouldnt have di water stored in a pressure tank. I cant remember the exact reason but i think it has something to do with the rubber inside of the tank.
