You've heard about the benefits of 'activated carbon' but exactly what is it? and how can you get the best out of your carbon cartridge?

What are Carbon Water Filters?

UV Water Systems Ltd use triple filtration in their UV water filtration systems because they feel a Carbon Filter is a “Must Have”.

Carbon filters work as a mechanical filter, this is a physical barrier that sediment can not pass through, but also more importantly, absorb organic compounds due to the properties of the activated carbon.

What is Activated Carbon?

 Carbon is heated in the absence of oxygen to 540degC, baking off impurities. The carbon is then activated by treating it with super heated steam to a temperature of 870degC.

This heating and treating process creates very small holes/pores and cracks over the surface of the carbon, this greatly increasing the surface area.

A greater surface area means that a larger amount of carbon is exposed to the water, the more carbon is exposed, the greater the filtration and absorption.

What do Carbon Filters remove?

Carbon cartridges work on surface contact. If the surfaces get coated ('slicked up') this creates a barrier, which effectively renders the carbon useless. For this reason it is good practice to have a 'sacrificial cartridge in front'. This is normally a depth cartridge of 1 micron. Evidence of this is particularly acute for mains water filtration where the main goal is removal of chlorine.
