Pentek RFFE-20BB Iron Reduction Filter Video




Welcome to the Pentek RFFE-20BB Iron Reduction Filter Video Page. The Pentek RFFE-20BB filter is a Radial Flow Iron Reduction water filter cartridge designed to effectively reduce up to 3 ppm of dissolved iron from water. Using the RFFE20BB filter cartridge reduces the possibility of plumbing and water heater problems and will help to eliminate the rust stains often found in sinks, tubs, and toilets. It is completely safe for drinking water applications and adds no harmful chemicals. For best results, pre-sediment and post-carbon treatment is recommended. For pre-sediment filtration, use the P5-20BB-WF sediment filter. For post-carbon filtration, use the RFC-20BB radial flow carbon filter. Water conditions outside of the specified limits will lead to shortened filter life. If your water contains Iron Bacteria, shock chlorination with the Well Safe Well Sanitizer Pack is recommended. NOTE: The RFFE-20BB cartridges will release a very small amount of fines (very fine powder) and requires flushing when first installed. This is a compatible filter to the Everpure DEV910846 filter. The Pentek RFFE-20BB is sold under many different brands including, Pentek / Ametek / Culligan / Kleen Plus / Plymouth Products / Pentair / American Plumber / US Filter.

Pentek RFFE-20BB Iron Reduction Filter Video Transcript

Hey everyone; Aquaman here with Water Wisdom sponsored by WaterFilters.NET. Todayís video is both about this particular cartridge, this is an iron oxidizing cartridge (part # RFFE-20BB), and this video is also about iron in general in your water. Now, iron is going to exist primarily in untreated waters, especially well waters. It can be very complicated, but Iím going to boil it down to some general things. For starters, iron exists in your water in primarily 3 forms; one of them is iron bacteria. It isnít exactly rare, but itís something that requires special testing, that youíre not going to know you have it until you realize that other solutions arenít working. So, thereís no easy way to isolate it without starting out, right out of the box, with a fairly expensive, high quality laboratory test of your water, that can verify exactly if you do or donít have iron bacteria. Iron bacteria is very different from just plain elemental iron in your water. It exists in 2 primary forms. One is the regular non-oxidized form; this is ferrous iron, and the other is the oxidized form called ferric oxide. Ferrous iron is dissolved in the water. You canít see it, you canít taste it, but itís there, and when it becomes exposed to oxygen it will precipitate out of the water in the form of a rust particle; now itís ferric oxide. Ferrous iron can pass right through this filter, or any other filter, but ferric oxide will get captured by a sediment filter. So, if you have an iron problem, one of the ways that it can be dealt with depends on the level of the iron. Itís pretty common for iron to be less than 3 parts per million; again good testing will reveal this to you. The RFFE-20BB is an iron oxidizing filter that uses a potassium permanganate impregnated Zeolite media. Itís just a microscopic granule that microscopically has many intercostal spaces, and it is coated with and impregnated with potassium permanganate which is a very strong oxidizing agent. So, the ferrous iron enters this filter, becomes oxidized, precipitates out of the water solution in the form of a rust particle, and then you have either a sediment filter like this or in some cases a carbon filter that captures the oxidized particles out of the water. So, your iron problem; some people come to me and they say, well I have rust in my water, well thatís not the whole picture. Theyíve got ferric oxide, because some of the ferrous iron has already oxidized and is now in particle form and can be captured, and theyíre seeing that in their toilets, in their dishwashers, in their washing machine staining on their laundry, but putting just a sediment filter in will remove the already oxidized ferric oxide, but then the ferrous iron that remains on the other side of the filter will eventually get exposed to oxygen and become ferric oxide and form rust particles and show up downstream after the filter. This unless you first oxidize the iron with an oxidizing filter, and then all of the ferrous iron has been oxidized and can be captured by a sediment filter or a carbon filter. Now as I indicated the RFFE-20BB is only good up to 3 parts per million, so if you have a severe iron problem of 4 or 5 or 6 parts per million, thereís no cartridge in the world that can fix your problem, you need a full-fledged tank style system. This is a 12 inch diameter tank, 50 inches tall with one of those electronic valve heads on top, and this is a system that will have an oxidizing media and it will automatically backwash itself with this valve head. A much more complex system, youíre looking at a minimum of $900 to $1000 for one of those, possibly more depending on what other peripheral equipment you need for that severe water problem, but less than 3 parts per million iron, you can use the RFFE-20BB to oxidize the ferrous iron, turn it into ferric oxide and then capture it with another filter after this. One more minor problem; if youíve got a serious iron problem you probably have some of the iron already in the ferric particle form before it gets to this filter, and unfortunately this RFFE-200BB is going to clog much more rapidly if it is capturing all of the already oxidized ferric oxide particles. So, you really need 3 filters to do it right. You need a sediment filter before the iron oxidizing filter, and then a sediment filter or a carbon filter after the iron oxidizing filter. Now, the reason they often use a carbon filter after the iron oxidizer is because of the troublesome trio. The troublesome trio is Iron, Manganese and Hydrogen Sulfide. Manganese is another metal that is dissolved in the water and when it oxidizes it forms a very difficult to remove black stain. Where there is heavy iron, there is almost always manganese, and there is almost always also Hydrogen Sulfide. Hydrogen sulfide is a gas that smells like rotten eggs. If you have a rotten egg smell, you have hydrogen sulfide gas. Now, this filter will not deal with, the oxidizing filter will not deal with the hydrogen sulfide, but a carbon filter after it will. So, thatís why you have the threefold system. You have a sediment filter to protect the oxidizing filter from getting clogged rapidly, then you have the oxidizing filter to take the ferrous iron and turn it into ferric oxide particles, and then you have a carbon filter after to capture the ferric oxide and to deal with the hydrogen sulfide problem which probably exists if youíve got a sever iron problem. So, this is the RFFE-20BB, and this is iron; iron is tough stuff, itís hard to get out of the water but if you do it right it can be managed. If you have any questions, call the technical department at WaterFilters.NET, we can definitely help you find what you need. Iím your host Aquaman; thanks for watching!
