Pet Forum / Aquaria / Marine Reef / September 2007Home Water Purification Systems
I am about to get a water purification system for my house which uses a KDF-55 pre-filter. Anyone out here have any experience with this? I've searched old forums, but no joy. I don't want to ask the company rep about it; they'd just probably shoot me a line anyway...

Did you ask what is inside KDF-55 "prefilter"? And how is the main filter working? Such systems are usualy water softener systems... Just to remove large rust particles and calcium hardness. For reef tanks we usualy use multi-stage filters with main stage being reverse-osmosis (RO) and the last stage using ion-exchange resins (called de-ionisator, DI) further polishing water coming out from the RO filter. As a result we receive pure water, cleaner than distilled water you can get in the grocery stores. Rather than whole-house purification system we use such RO/DI filters just for drinking water and to fill up tanks for mixing saltwater. It helps to have the brand name, company name, company address, company phone number, web address, e-mail address, and such for searching such information about some product number "KDF-55".

It doesn't have DI, just RO. The company is Aqua Solutions in Los Angeles. http://www.advancedaquasolutions.com/5-stage.html > > It helps to have the brand name, company name, > > company address, company phone number, web address, [quoted text clipped - 11 lines] > > http://www.advancedaquasolutions.com/5-stage.html Piece of sh.t reallay. Check out filtersdirect.com and get a decent rodi unit and not get f.cked inthe process. Its hard to beat a unit with clear housings..........solid color housing leave al ot to be desired............ Filters Direct has them for $122.00 delivered with your choice of membrane capacity from 35 to 100 gpd and all american made as well., Its comonly called Water General........do an Ebay search, then call and ask for Oscar...............and BTW the filter direct Water General is made by Honeywell Systems.Aquatechnics division...far from being a piece of junk! On that web site is says: # "We begin with a First Stage Pre-Filter, which removes particles in the water down to 5 microns. This sediment filter is designed to protect the membrane from fast deterioration." # This just removes dirt and other particles. # " The Second Stage Filter is a combination of a copper-zinc alloy (KDF) and Activated Carbon, which removes chlorine and other organics and helps prevent bacteria and algea growth. " # This removes more stuff from the water, making it more drinkable. # "The Third Stage Filter is a T.F.C. (Thin Film Composit) Membrane, to ensure the highest level of rejection" # This is an RO unit using "Thin Film composite" abbreviated as "TFC" So if you do a search on the different types of membranes you will see the advantages and disadvantages of the different membranes. Kent Marine (http://kentmarine.com) has documented a lot of good information on the different types of membranes. The reason that the system has other filters before the RO is just like with any RO unit, if you don't filter out the bigger stuff, it will quickly clog the membrane, and some membranes will be damaged by chlorine if it is not removed. Your homework assignment is to read up on the different types of RO membranes and become familiar with the differences :-) Wayne Sallee Wayne@WayneSallee.com Dave wrote on 9/10/2007 12:14 PM: >> It helps to have the brand name, company name, >> company address, company phone number, web address, [quoted text clipped - 11 lines] > > http://www.advancedaquasolutions.com/5-stage.html |
