Zhongchuang has focused on the production and sales of activated carbon for decades. We are familiar with the application and common sense of activated carbon.
When using activated carbon in water treatment, we need to pay attention to some items so that we can ensure the efficiency and safety. And the following matters need to be noted to ensure its maximum efficiency and safety, today we will talk about it.
Powdered activated carbon (PAC) can be added before coagulation, during chemical addition, or during the settling stage, prior to sand filtration.
Powdered Activated Carbon (PAC) is a widely used adsorption medium in municipal, industrial and emergency wastewater treatment for removing dissolved organics, color, odor and toxic pollutants while significantly reducing COD.
As silicon-carbon anodes become the mainstream solution for high-energy-density lithium batteries, silicon volume expansion during charge-discharge cycles remains a key industry bottleneck. Our silicon-carbon anode porous carbon — made from premium coconut shell biomass via advanced steam activation — effectively solves this problem as a core carrier and buffer material for silicon-carbon anode systems.
Coal-based Granular Activated Carbon (GAC) is the core filtration medium for fixed-bed water treatment systems, widely used in municipal drinking water purification, industrial advanced wastewater treatment and reverse osmosis pre-treatment.
In gold cyanidation processes, coconut shell granular activated carbon (GAC) is widely used to adsorb gold cyanide complexes from pregnant slurries, primarily in CIL (Carbon-In-Leach) and CIP (Carbon-In-Pulp) circuits. Unlike single-use powdered carbon, GAC can be regenerated thermally and reused multiple times. However, after repeated cycles, its adsorption capacity and mechanical strength gradually decline, making periodic replenishment of fresh carbon and discharge of spent material essential. For plant operators and procurement managers, the carbon consumption rate (including physical attrition and chemical deactivation) is a key factor directly impacting gold recovery costs.
Once powdered activated carbon (PAC) reaches adsorption saturation, its purification efficiency for water or waste gas declines significantly. Therefore, timely replenishment or replacement is essential. Unlike columnar carbon, PAC is typically used in a single-pass, non‑regenerable manner – it is dosed continuously or batchwise and then removed via sedimentation or filtration. Under standard industrial operating conditions, the “replacement cycle” is not measured in months but in hours or even minutes.
Once columnar activated carbon reaches adsorption saturation, its purification efficiency for waste gas or liquid streams declines significantly. Therefore, periodic replacement is essential. Under standard industrial operating conditions, a typical replacement cycle ranges from 6 to 12 months – longer than granular activated carbon in some applications due to its higher mechanical strength and lower pressure drop characteristics.
Leveraging its unique honeycomb monolithic structure and high specific surface area, honeycomb activated carbon efficiently removes volatile organic compounds (VOCs), malodorous gases and fine particulate matter from industrial flue gas, significantly improving exhaust gas emission standards and reducing environmental pollution.
Due to differences in raw material processing, coal-based granular activated carbon and coconut shell granular activated carbon each have their own advantages in microporous structure, mechanical hardness, purification effect, and applicable water treatment and air purification scenarios. They are two commonly used and distinctly different adsorption materials in industrial purification.
Leveraging its developed pore structure and high specific surface area, coal-based granular activated carbon efficiently removes refractory organics, toxic substances from chemical wastewater, significantly reducing COD and color.
