As with all Omnipure filters, the Q-Series is ideal for use in any situation where better tasting, sediment-free water is required – beverage equipment, RO systems, drinking fountains, ice machines, and other point-of-use applications.
Standard media includes granular activated carbon for taste and odour reduction, polypropylene depth filtration for removal of grit and sediment, and polyphosphate to control lime and scale deposits. Also, a wide variety of specialty and custom media options are available.
Replacement of the spent media is quick and simple, by detaching the filter body from a permanent head with a twist of the wrist. The new filter body is just as easily threaded into the head and the replacement is then complete.
The Q-Series is also available with the optional Twist Tap in-head valve system, which automatically turns the supply water off when the body is disconnected from the head. No tools. No drips. No hassles.
A sediment filter`s main purpose is to remove particulates from water. It is rated by a micron number which refers to the size of the particles that the filter will trap. These are often required as a pre-treatment for other types of treatment such as reverse osmosis and carbon filtration. Keep in mind that sediment filters only reduce particulates. They do not remove chemicals or make the water taste or smell better.
The carbon water filter cartridge is a standard size 100% coconut carbon (not a coconut/coal blend) for sweeter tasting water. Removes chlorine, taste, cysts and odours.
In order to remove cryptosporidium and giardia a water filter cartridge must be absolute 1 micron, this cartridge is NSF approved and will remove >99.99% of cysts from the water.
Carbon filtering is a method of filtering that uses activated carbon to remove contaminants and impurities, taste and odour using chemical adsorption.
Each granule of carbon provides a large surface area structure, allowing contaminants the greatest possible exposure to the active sites within the filter media. One pound (450 g) of activated carbon contains a surface area of approximately 100 acres (40 Hectares).
Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon . Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing. It is also used in a number of other applications, including respirator masks, the purification of sugarcane and in the recovery of precious metals, especially gold.
Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odour from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. Reverse Osmosis is the best filtration for dissolved compounds.
Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. However, the amount and quality of carbon is also very important factor. The particle size will be used as part of the filter description. The efficacy of a carbon filter is also based upon the flow rate regulation. When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time.
There are 2 predominant types of carbon filters used in the filtration industry: powdered block filters and granular activated filters. In general, carbon block filters are more effective at removing a larger number of contaminants, based upon the increased surface area of carbon. Many carbon filters also use secondary media such as silver to prevent bacteria growth within the filter. Alternatively, the activated carbon itself may be impregnated with silver to provide this bacteriostatic property.
