Carbon Filter Systems


Carbon water filtration systems simply put, are used to remove undesirable odors and tastes from our household water. But recent years we have found they can help prevent pinhole water leaks in copper piping.

Activated Carbon works using a process called adsorption, whereby the pollutant molecules in the water are trapped inside the pore structure of the carbon substrate

What is ADSORPTION?- the adhesion in an extremely thin layer of molecules to the surfaces of solid bodies or liquids with which they are in contact with.

Basically, as the water passes by the carbon granules the “bad elements” are trapped to the surface of the carbon granule.

Carbon is a great media used to remove chlorine and chloramines from household water supply.

Chlorine – Chlorination is the process of adding chlorine to drinking water to disinfect it and kill germs. It is a chemical that is often adsorbed into foods like sauces and hot drinks, adding unwanted taste. Most high-end restaurants, chefs and even coffee shops use filtered water for this reason.

Showering or bathing in chlorinated water affects your skin and hair. Your skin is the largest body organ, able to absorb chlorine (even from vapors and steam). This can leave your skin itchy and uncomfortable. The chlorine can also dry out your hair, requiring the extensive use of conditioners for your hair and for dyed hair (colored) you may also bleach out the color. People with blonde hair have complained chlorine turns their hair green.

Chloramines – Many public water systems add chemical disinfectants to their water. The standard used to be chlorine, but the water companies found it too unstable (it evaporates easily, which was great for removal since you could boil it off or simply let the water sit out for a few hours), so they switched to chloramine, which is chlorine and ammonia bonded. Both EBMUD and SF Water use chloramine as a disinfectant. As well as many Orange County water providers

A condominium association served by Moulton Niguel Water District has sued the agency over copper pipe leaks that owners believe are caused by corrosive water and that have led to hundreds of thousands of dollars in repairs, according to court documents.
In the suit, attorneys for 248-unit Briosa Owners Association point the finger squarely at chloramines, a drinking-water disinfectant formed by adding ammonia to chlorine. The lawsuit states “chloramine has been known to be corrosive to copper pipes and cause leaks,” and because of it, Briosa’s owners “have experienced a dramatically high number of leaks in their copper water supply pipes.”

Not all carbon medias are the same.

Basic types of carbon filters

GAC (granular activated carbon) These filters contain fine grains of activated carbon. They are typically less effective as carbon block filters because they have a smaller surface area of activated carbon. Their effectiveness depends on how quickly water flows through.

Carbon Block Carbon block filters contain pulverized activated carbon that is shaped into block under high pressure. They are typically more effective than granulated activated carbon filter as they have more surface area. Their effectiveness depends on how quickly water runs through it.

Catalytic Carbon Block Catalytic carbon is a specially processed filter medium designed to greatly enhance carbon’s natural ability to promote chemical changes in contaminants. Standard filter carbon reduces contaminants in two ways. It “adsorbs” chemicals by trapping and holding them, and to a smaller degree, it “chemisorbs” contaminants by changing them to something harmless. Chlorine, for example, can be “catalyzed” to harmless chloride

Catalytic carbon retains conventional carbon’s ability to adsorb contaminants but it also possesses greatly enhanced capacity to catalyze, to promote beneficial chemical reactions. It is by catalytic action that chloramine is greatly reduced.

Aqualistic uses only Catalytic Carbon Block media in all our systems, that is why we can give a 10 year 2-million-gallon guarantee! Catalytic Carbon gives you the most powerful protection from chlorine and leak causing chloramines you can get.
