1. Activated carbon-sand filter double-layer filter material filter, that is, columnar activated carbon replaces part of the sand filter material in the original sand filter. Charcoal-sand double-layer filter media. honeycomb activated carbon  After the adsorption of the carbon layer and the filtering use of the sand layer, it can effectively remove organic pollutants in the water. It can also remove ammonia. In order to meet the requirements of filtration and adsorption, it is common to spread 12×40 mesh or 8×30 mesh activated carbon (active carbon mesh) on a sand layer tens of centimeters thick. The activated carbon layer with a thickness of 40cm is sufficient to remove organic matter, which can reduce the amount of chlorine required and eliminate odors. And it has the talent to remove pesticides and other organic matter, and the service life is 0.5 to 5 years. 2. Use columnar activated carbon to replace all sand filter materials in the sand filter to make honeycomb activated carbon for adsorption and filtration purposes. 3. Separate activated carbon pool after the fast filter. That is, the GAC filter is arranged behind the sand filter. Hold a secondary filtration. The sand filter must cut off the alum. The activated carbon pool adsorbs organic matter, phenol and odor.www.wyactivatedcarbon.com  Compared with the above two processes, the cost of capital construction of a single activated carbon pool is higher. But it can use more activated carbon adsorption, lower operating costs, easy to change activated carbon, and can more effectively remove TOC, volatile organic compounds and special organic compounds.
What is the role of powdered activated carbon in water treatment0dingxinda92021-03-01 01:04:46
Generally, activated carbon for water treatment is nothing more than nut shell activated carbon, coconut shell activated carbon, powdered activated carbon, and columnar activated carbon. These types of activated carbon can be used in water treatment, which can play a role in deep purification of water quality. Filter tanks use granular activated carbon to purify water. Compared to if shell activated carbon, coconut shell activated carbon and coal columnar activated carbon, this type of activated carbon has strong adsorption capacity and low ash content.  bulk activated charcoal pellets   Another point is that it can be filled into the container to filter and use. More convenient. Powdered activated carbon is suitable for the purification and decolorization of colored sewage. When the water is colored, granular activated carbon can remove part of the color, but it is difficult to remove it completely. At this time, powdered activated carbon is needed for treatment. The powdered activated carbon has a huge pore structure that can absorb the colors in the water while also adsorbing organic matter and harmful bacteria in the water. activated coconut charcoal powder It is just that the powdered activated carbon needs to be added when it is used. After thorough mixing, the filtered powdered activated carbon is finally removed. The procedure is more cumbersome compared to other activated carbons. However, the purification and decolorization ability of powdered activated carbon is much better than that of other activated carbons. Generally, powdered activated carbon is used for decolorization of food, wine, and medicine.

How does activated carbon play a role in modern water treatment?0dingxinda92020-10-16 00:24:38
Activated carbon filtration is one of many processes commonly used in water treatment to remove contaminants such as organic materials, and since it also can remove odor-causing contaminants, it’s often used to make drinking water more palatable.ningxia activated carbon The first known carbon filtration devices date back to ancient Minonan Crete.The water was carried through a 3-km aqueduct, and several cone-shaped terra cotta filters filled with charcoal were discovered in the system. Activated carbon filter technology has improved with time, and today the activated carbon market is predicted to grow, with water treatment driving the growth, although the COVID-19 pandemic has introduce some uncertainty in activated carbon market predictions. Activated carbon is frequently chosen for potable water applications because it efficiently adsorbs synthetic organic chemicals, PFAS, chlorine, compounds that affect smell and taste, and naturally occurring organic compounds. As pollution and contamination gets worse, particularly in the developing world, activated carbon filtration is poised to grow. Water treatment plant operators have two choices when using granular activated carbon filtration,Retrofitting an existing multimedia filter — typically a bed filter — by replacing its medium, or installing a new filter. Both methods require calculations of bed depth, water flow, and other factors. Operators must also allow for seasonal changes in water that may mean more frequent backwash is required. Granular activated carbon can be reactivated through thermal oxidation, which allows it to be used multiple times. Granulated activated carbon filtration can be used on its own or paired with other technologies for disinfection or other processes to achieve desired water quality. For example, it can be used with ozone in a treatment known as a biological activated carbon process. Researchers continue studying the medium, which is still being widely applied in a variety of applications, for instance, activated carbon used with coagulation and filtration for advanced wastewater treatment. A granulated activated carbon unit is most often placed in a water treatment plant after conventional filtration processes, or after a process such as flocculation and sedimentation, according to the U.S. Environmental Protection Agency.www.activated-carbon-pellets.com

Adsorption capacity refers to the amount of adsorbents adsorbed on the adsorbent per unit mass under certain conditions. It is usually expressed in terms of K adsorbents /kg of adsorbent or mass percentage, which is a sign of the adsorption capacity of the adsorbent. In industry, the amount of adsorption is called the activity of the adsorbent.activated carbon powder suppliers  The activity of the adsorbent can be expressed in two ways :(1) the static activity of the adsorbentUnder certain conditions, the equilibrium adsorption capacity of the adsorbent is its static activity.For a certain adsorption system, the static activity depends only on the adsorption temperature and the concentration or partial pressure of the adsorbed substance.https://www.activated-carbon-pellets.com   Dynamic activity of adsorbents Under certain operating conditions, the gas mixture by adsorption bed, adsorption by adsorption, adsorption after a period of time, when starting from the adsorbent in the laminar flow of the gas adsorbed mass (or its concentration reaches a specified value), think bed fire, adsorption properties of adsorbent adsorption quantity at this time is called dynamic activity of adsorbent. The activity is not only related to the characteristics of adsorbents and adsorbents, but also related to temperature, concentration and operating conditions.
