Granular activated carbon in Korea
Granular activated carbon in Korea and all over the world is one of the most versatile and extensively used forms of activated carbon on the market. Even though the primary qualities are the same, based on raw materials, manufacturing process, and size, the properties of activated carbon can slightly change and can be used to achieve targeted applications. Activated carbon manufacturers in Korea produce activated carbon according to industrial demands, and granular activated carbon (GAC) is one of the most in-demand types of activated carbon, especially for water purification. Here, we will discuss the manufacturing methods, unique properties, and applications of granular activated carbon.
Activated carbon manufacturers in Korea
Asia-Pacific is one of the most prominent markets for activated carbon. Food and beverage processing, water treatment, and air purification are a few of the main industries aided by activated carbon manufacturers in Korea. Granular activated carbon in Korea is a preferred type of activated carbon due to its efficiency and durability compared to powdered activated carbon (PAC).Powdered activated carbon generally showcases a slightly high microporosity compared to granular activated carbon, and it increases the adsorption capacity of PAC. At the same time, the small particle size of powdered activated carbon can also slow down settling, and compared to granular activated carbon, PAC has lower durability and is harder to separate. When it comes to water treatment, granular activated carbon in Korea is generally considered a better option because of its durability, cost effectiveness, and minor environmental consequences.
Granular activated carbon preparation
Activated carbon manufacturers in Korea and around the world prefer hard organic materials such as coconut husk and wood as raw materials for the preparation of granular activated carbon. There are many methods to produce granular activated carbon in Korea, and based on the method of production, the final product will have slightly different characteristics. So according to the application, manufacturers can produce customised activated carbon by changing the manufacturing process.The first step in any activated carbon production is acquiring and preparing the raw materials. The pre-treatment of these raw materials is an extremely important step; the raw materials are first washed to remove any debris and then dried to remove any moisture from them. To even the size and burning, the raw materials are then crushed in a hammer mill. After the pre-treatment, the raw materials go through carbonization and activation processes to finally produce the activated carbon.Activated carbon manufacturers in Korea use both physical activation and chemical activation methods to produce granular activated carbon according to the specific application of the final product. Apart from carbonization and activation, granulation is the additional step to produce granular activated carbon in Korea. Granulation can be done with or without binders, and it can be a following step after carbonization and activation or in between them.The quality of granular activated carbon is influenced by many factors, such as the moulding pressure, mixture ratio, activation method, usage order of activation agents, and temperature throughout the manufacturing process, but with a curated manufacturing process, these factors can be adjusted to form our ideal product.
Applications and qualities of granular activated carbon
Granular activated carbon is used in a number of industrial processes, but the main applications are water treatment, air purification, and removing adverse odours and colours from food and beverages. With a particle size that ranges between 0.2 and 5 mm, granular activated carbon features a huge number of micropores and a large surface area.
Water purification
Water treatment is one of the major applications of granular activated carbon in Korea. Activated carbon manufacturers in Korea supply granular activated carbon for both industrial water treatment processes and home water purification systems. Water treatment, in general, is a process that contains various steps to eliminate all kinds of pollutants from water; for example, a wastewater treatment facility and a sea water purification facility might have different steps in different orders.Pesticides, natural organic matter (NOM), microbes, heavy metals, pharmaceutical products, disinfectant byproducts, EDC’s, and dyes are a few of the contaminants that are often seen in water. Granular activated carbon is integrated into various water treatment steps to adsorb and remove these contaminants. Apart from industrial-level water treatment applications, granular activated carbon is widely used in house water filter systems too.
Durability: Granular activated carbon in Korea is widely used in the water treatment industry due to its high adsorption quality, but one of the most remarkable qualities of granular activated carbon compared to PAC is its durability. Unlike powdered activated carbon, granular activated carbon can be recycled and reused in purification processes via thermal reactivation.
Cost effectiveness: Efficiency and reusability are the most unique characteristics of granular activated carbon. So when you purchase granular activated charcoal from activated carbon manufacturers in Korea or anywhere else in the world, even though the initial costs might be slightly higher than those of powdered activated carbon, in the long run, it will prove to be a cost-effective choice.
