Coconut Shell Based Activated Carbon
The use of activated carbon to remove harmful impurities like organic contaminants from water has been practiced since Roman times. Activated carbon is a carbonaceous adsorbents with extensively developed internal pore structure. Activated carbon is extremely porous with a very large surface area, which makes it a powerful adsorbent material. This large surface area relative to the size of the actual carbon particle makes it easy to remove large amounts of impurities in a relatively small enclosed space. An approximate ratio of surface area is one square meter per gram. The two mechanisms by which the chemicals are adsorbed onto activated carbon are either it ‘dislikes’ water or it attracts…
In Sweden, sweat machine turns perspiration into drinking water
The global water crisis has inspired innovative ideas for conserving water — or finding filtered to remove any salt, bacteria and other textile bits — and guess what, tasty drinking water! Would you like to try?
Should I use carbon filtration in freshwater aquariums?
Using carbon filtration in freshwater aquariums has become one of the hot trends nowadays. However, it’s at the same time a heated controversy. As a spectator, I want to cleat that carbon use is optional and it’s always a personal choice. I have tanks that use carbon and those that don’t. This article is my experience that provides some details about the use of carbon, which may allow aquarists like you to decide if carbon filtration is worth trying or not. Compared to carbon-zero tanks, I realized that carbon removes dissolved organics and toxins. It does it via two ways, adsorption and catalytic reduction. In general, organic particles are removed…
Activated Carbon & Water Filters
Carbon is a substance that has a long history of being used to adsorb impurities and is perhaps the most powerful adsorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can adsorb literally thousands of different chemicals. Activated carbon is carbon that is electro-positively charge, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules. Activated carbon filters used for home water treatment typically contain either granular activated carbon (GAC) or powdered block carbon. Although both are effective,…
Beware of Bottled Water – Little thought for your health
In a hot summer day, I was in a supermarket trying to find some sparkling water to kill my thirst. Stopped in front of different brands of bottled water, I was confused. There were so many labels of pure springs and ice water that almost convinced me the liquid inside these bottles is the purest drink around. But then, a thought hit my mind: labels could be misleading, or sometimes deceptive. I remember in one case, water coming from a well located near a hazardous waste site was sold and labelled as “spring water.” I withdrew my hand from these bottles and decided to find out the best water solution.…
