Things You Need To Know About The Activated Carbon Blocks

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions.

Due to its high degree of micro-porosity, one gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq ft) as determined by gas adsorption. An activation level sufficient for useful application may be obtained solely from high surface area. Further chemical treatment often enhances adsorption properties.

In the process of filtering water, activated carbon is often used to remove contaminants and impurities. Carbon is probably the most absorbent material known to human, and it is uniquely efficient because of thousands of tiny pores that can absorb.Carbon filters made from powdered carbon blocks are more efficient than granular activated carbon because the blocks are denser, slowing down the passage of water through them.

The larger surface area created by the block carbon, and the more time the water is in contact with the carbon, the more contaminants are removed.Activate carbon water filters are rated by the size of contaminants they remove. These range from around 50 microns down to .5 microns. The smaller the measurement the more effective the filter.

coconut shell carbon blocks
Different substances are used to make the carbon for these filters, such as bituminous, wood and coconut shell.

Of these, coconut shell is the most expensive, but has been found to also be the most effective. It has the ability to remove even the smallest particles of contaminant.Also, coconut shell-based carbons tend to be harder,more resistant to abrasion, and lower in ash than similar grades of coal-based carbons.
The major advantage with the coconut shell activated carbon is that it is an outstanding material for applications requiring taste, odor and dissolved organic chemical removal from water with suspended particle present.

In addition, its balanced pore structure gives a more efficient adsorption range and it imparts a high “polish” to the filtered water.

Pursafet carbon blocks filters raw materials are from Jacobi high-grade coconut shell based carbon,delivers an unmatched purity and micro-pore volume than than other carbon source.

Pursafet carbon block filters are manufactured entirely from FDA-compliant and NSF certified,making them an ideal choice for a wide range of residential, food service, commercial and industrial applications.

Water and coffee

The taste of water and its impact on coffee

Dissolved minerals can have a significant impact on a coffee’s flavor profile, as they affect the way the water extracts coffee from grounds.
In addition, some minerals interact with components in coffee.

Hydrogen carbonate, for example, reacts with coffee acids and, in certain quantities can lead to a  “flat”, unbalanced flavor.

Moreover, substances introduced during water treatment can cause unpalatable chlorine, corky or musty tastes. Some entrained materials can even influence how coffee smells – altering its aroma profile.

Plus, organic contaminants in water can often lend an off-flavor to coffee. In particular, water with these types of solutes can produce coffee with a distinctive earthy or musty taste (geosmin).

Pursafet offers water filters works according to the professional up-flow principle, always filtering the precise amount of water required for each job. As well as limescale, it filters out heavy metals and substances like chlorine that could affect smell and taste. The result: pure water for your favorite specialty coffees and a longer life for your investment.
