So most of you are familiar with the 10" x 2.5" carbon blocks used in RODI systems. What do you do if the flow you're trying to treat is more/faster than that filter can treat? We'll you can always go with a larger carbon block at 20" x 2.5" or 10" x 4.5" of 20" x 4.5". The largest of these will allow flows between 5 and 10 gallons per minute.
What if the desired flow is higher/faster than that? What if you're trying to treat 75 gpm - something like you'd see out of a 2" firehose. These sorts of flows are most economically treated with a backwashing carbon tank. Here's one we recently worked on that is 3 feet in diameter and almost 7 feet tall that holds 20 cubic feet (550 lbs) of granulated activated carbon.
The old carbon inside had to be removed, and new carbon loaded. We use this style of backwashing carbon tank at public aquariums and other commercial applications, and in front of commercial-sized RO and RODI systems.
