Need advice/help on CARBON w/ water softener

I need to replace my water softener and have done a ton of research and need to pull the trigger but am confused.

I would like to buy the 5600 for approx $500 for Ohio Pure Water Co. but it doesn't have any carbon....

Since I don't want to manually change the carbon monthly, the only option that I was given was a dual tank (one dedicated for carbon) which would cost $1100-1200.

Isn't there a softener that has carbon in it that doesn't require me to mess with it in the $500-$800 range.

My understanding is that if I mix the carbon and resin in the same tank, the resin won't last.

Please help me move off center and order it.

Thanks in advance....

Carbon & resin in the same tank

Carbon & resin CAN be combined in the same tank without compromising the lifespan of the resin. If anything, the dechlorinating ability of the carbon will PROLONG the life of the resin.

When combining resin & GAC, be sure to have a valve that backwashes rapidly enough and that you sanitize the system periodically with a non-oxidizing disinfectant.

carbon filtration

You didn’t mention but I will assume you want the carbon to take chlorine out of the water on a municipal supply.
Softener Ion exchange resin and Carbon have different backwash rates and different densities. Carbon added to the resin tank after backwash will work its way to the bottom of the tank and since the inlet water in almost all water softeners is down flow, there will be no de-chlorinating benefit to the ion exchange resin at all. Without an oversized tank and custom design, Backwash rates for each material are different, with carbon requiring much more backwash flow then softening resin. With the carbon being denser and on the bottom of the tank it will very difficult to ever change it with out removing the softening resin top layer first. Your better off using a separate backwashing carbon filter that you should be able to find for less than a water softener. If you are not on a chlorinated supply of water, I wouldn’t recommend any carbon filter for a whole house situation at all for fear of bacteriological growth in the carbon.
“AC filters can be a breeding ground for microorganisms. The organic chemicals that are adsorbed to the AC are a source of food for various types of bacteria. Pathogenic bacteria are those that cause human diseases such as typhoid, cholera, and dysentery. Public water systems must treat for disease causing bacteria; therefore, the likelihood of disease causing bacteria being introduced to an AC filter from public drinking water is remote. AC filtration should only be used on water that has been tested and found to be bacteria free or effectively treated for pathogenic bacteria.” (Above paragraph-Bruce Seelig, Water Quality Specialist, North Dakota Extension Service)
