Carbon Block Water Filters

Over the next three weeks we will be publishing articles on the use of Carbon block in water filters. We will start off with an introduction to the product, followed by an article on carbon block engineering and conclude with a description of the manufacturing process.

Carbon block is used in a wide variety of applications and performs a wider range of filtration tasks than other products. How carbon block is engineered will determine its use.

Carbon block is the workhorse of water filtration technologies, performing a wider range of filtration tasks than other products. Its sintered porous structure made of powdered carbon, thermoplastic binders and other additives, allows for the removal and retention of both sediment and organic chemicals in just one filter. Carbon block offers the opportunity for very fine sediment filtration and absolute control and filtration of very fine particles to less than 1 micron in size. At the same time, carbon block can be formulated to remove any number of chemical contaminants that may be present in the water.

Specifically, carbon block can reduce
• Chlorine,
• Bad taste and odour,
• Chloramines,
• Fine sediment,
• Giardia and Cryptosporidium cysts,
• Organic chemicals such as pesticides and solvents, and
• Heavy metals such as lead and mercury.

Water is forced through the porous structure of the densely compacted carbon block, and filtration is accomplished by mechanical separation of sediment and adsorption of chemical contaminants by the activated carbon or other additives.

Carbon block works in a wide variety of applications including point-of-use (POU) and whole-house residential water filtration, commercial water treatment, pre- and post-filter reverse osmosis (RO) and industrial processes. In many applications, carbon block offers an additional advantage in that few, if any, fines are released because they are bound in the composite structure. Carbon block works well in almost any situation where activated carbon products are utilized.
