Product Information

Activated carbon filtration is an excellent water treatment method and technology. It solves many water-contamination issues that many of us have to deal with every day, but there are a few exceptions that you must consider. Properties of Activated Carbon", CPL Caron Link, accessed 2008-05-02". Archived from the original on 19 June 2012 . Retrieved 13 October 2014. While many filtration systems can be very expensive, filters created with charcoal are amongst the cheapest available. Charcoal filters are relatively inexpensive to produce, yet just as effective as many others; this makes them a great option for most households. Charcoal Filters are Easy to Maintain Molina-Sabio M.; Gonzalez M.T.; Rodriguez-Reinoso F.; Sepulveda-Escribano A. (1996). "Effect of steam and carbon dioxide activation in the micropore size distribution of activated carbon". Carbon. 34 (4): 505–509. doi: 10.1016/0008-6223(96)00006-1. The surface of conventional activated carbon is reactive, capable of oxidation by atmospheric oxygen and oxygen plasma [43] [44] [45] [46] [47] [48] [49] [50] steam, [51] [52] [53] and also carbon dioxide [47] and ozone. [54] [55] [56]

Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000m 2 (32,000sqft) [1] [2] [4] as determined by gas adsorption. [1] [2] [5] Charcoal, before activation, has a specific surface area in the range of 2.0–5.0m 2/g. [6] [7] An activation level sufficient for useful application may be obtained solely from high surface area. Further chemical treatment often enhances adsorption properties. Activated carbon filters are designed and tested to remove the 14 most common pesticides potentially found in water. These pesticides include Chlordecone (CLD/Kepone), Chlordane, Heptachlor, Lindane, and Glyphosate (Round-up). The National Institute of Environmental Health Sciences (NIH) defines pesticides as “any substance[s] used to kill, repel, or control certain forms of plant or animal life that are considered to be pests.” These substances include herbicides, insecticides, fungicides, and others. Because of the widespread use of these agricultural chemicals, they can easily reach water-bearing aquifers below ground. Pesticides can cause short-term adverse health effects, as well as chronic long-term health effects that can occur months or years after exposure. · Herbicides Activated carbon is usually derived from waste products such as coconut husks; waste from paper mills has been studied as a source. [8] These bulk sources are converted into charcoal before being 'activated'. When derived from coal [1] [2] it is referred to as activated coal. Activated coke is derived from coke. As mentioned, activated charcoal filters attract and adsorb unhealthy organic compounds, but allow other minerals to remain in the water. Unfortunately, this also means not all microorganisms are removed, and charcoal is often used along with other filters. Charcoal Improves Water FlavorMany create their own “dirty” water for this to ensure that it is easily noted how many impurities are removed. You can add coffee grounds, dirt, leaves, cooking oil, or other pieces of debris to your basic tap water; this is a fun step for children and makes the filtering aspect of the charcoal easily seen. How to Create Your Filter Experiment Radkevich, V. Z.; Senko, T. L.; Wilson, K.; Grishenko, L. M.; Zaderko, A. N.; Diyuk, V. Y. (2008). "The influence of surface functionalization of activated carbon on palladium dispersion and catalytic activity in hydrogen oxidation". Applied Catalysis A: General. 335 (2): 241–251. doi: 10.1016/j.apcata.2007.11.029. Ash reduces the overall activity of activated carbon and reduces the efficiency of reactivation: the amount is exclusively dependent on the base raw material used to produce the activated carbon (e.g. coconut, wood, coal, etc.). Carbon filtering is a method of filtering that uses a bed of activated carbon to remove impurities from a fluid using adsorption. The solid or skeletal density of activated carbons will typically range between 2000 and 2100kg/m 3 (125–130lbs./cubic foot). However, a large part of an activated carbon sample will consist of air space between particles, and the actual or apparent density will therefore be lower, typically 400 to 500kg/m 3 (25–31lbs./cubic foot).

To create your basic charcoal filter system, you will want to gather a few key materials that should be easy to find. If you cannot find the exact item mentioned, look for something similar that you have around your home or in your camping gear. The materials needed are:The European molasses number (range 525–110) is inversely related to the North American molasses number. Lehmann, Joseph S. (2009).

Activated Charcoal Review Sheet [ permanent dead link], USDA Organic Materials Review, February 2002. Activated carbon is most commonly used to filter water. It improves water quality, eliminates unpleasant odors, and removes chlorine and other pollutants. However, it’s not sufficient for eliminating certain toxic organic compounds, significant levels of metals, fluoride, or pathogens.
