Omnipure Carbon Block Cartridges

Description

Omnipure introduced its own carbon block filtration media in the spring of 1999. With the market demanding better, more refined filtration options, Omnipure felt the need to supply their customers the best media option available.

Omnipure’s engineering team created a new, state-of-the-art compression moulding process. This advanced method produces a strong, one-piece carbon block with an extended life. It is unsurpassed at removing chlorine, sediment, taste, odour and organic contaminants. Due to its highly uniform moulded structure, the Omnipure carbon block benefits include the elimination of carbon fines release, as well as channelling and bypass.

Features

Omnipure filters and cartridge elements are designed to flow in a radial, outside to inside direction resulting in low pressure drop, high flow rate and increased dirt holding capacity.

What is removed/reduced?

Contaminants removed from your drinking water are dependent on the micron and media of the filter cartridge. For examples, please refer to the table below.

In the case of Carbon filtration, Omnipure offer a range of cartridges with specific media properties that target particular contaminants in your water supply (e.g. heavy metals). For further assistance in choosing a cartridge to suit your needs please call our support team on 07 3395 1722

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 10″ x 2.5″ 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.
