Before we have learned Activated Carbon in the last blog, and we say Carbon Filter(CTO&GAC) is a series of sediment filter perfectly produce water. Activated carbon can eliminate chlorine in the water. The process can be regarded as Cl2. The reaction between water and carbon initiates the formation of Cl-, H+ and CO2
Oxidizing agents in water are removed by direct chemical reaction with the carbon. In this case, the chlorine is not adsorbed onto the carbon particle but chemically reacts with the carbon to produce carbon dioxide. As a result, carbon filters have an infinite capacity for chlorine removal. The carbon bed does not become saturated with chlorine as is the case for organic removal.
What are CTO&GAC?
CTO（Carbon Rod Filter Cartridge）
Carbon rod filter cartridge is also called sintered activated carbon filter cartridge, or CTO filter cartridge. Carbon rod filter cartridge is a new type of deep filter cartridge. It is made of high-quality activated carbon as raw material, and its structure is composed of low-hot-melt adhesive, continuously extruded, and then sintered and solidified at low temperature to form a certain strength.
GAC（Granular Activated Carbon）
Granular activated carbon is a material with a porous structure and a large internal specific surface area.The particle size is 500 ~ 5000μm, and the pore structure of GAC is generally with three-dispersed pore distribution. Due to its large specific surface area, microporous structure, high adsorption capacity and high surface activity, it has become a unique multi-functional adsorbent.
How to pick the best one for your CTO or GAC?
The smaller particle size and uniform pore structure of CTO provides a high level of effectiveness in a much smaller size than a GAC at the same flow rate. For this reason, GAC typically is used as a treatment method for aesthetic contaminants (removal of taste, odor and color).
CTO goes beyond the aesthetic improvement of water by reducing particulates, microscopic cysts, lead, volatile organic chemicals (VOCs), and other contaminants. For more details, pls feel free to contact [email protected]
