PAC Activated Carbon: The Blitzkrieg Expert in Industrial Purification

What is PAC? Form: Ultrafine powder with a particle size <0.18mm (equivalent to the fineness of flour) Core Weapon: Specific surface area 1500-2000m²/g (1 gram of carbon can cover 4 basketball courts) Working Principle: Molecular-level magnetic adsorption: Adsorbs pollutants through van der Waals forces Three-velocity pores: Micropores (<2nm): Lock in pesticide/heavy metal ions Mesopores (2-50nm): Capture dye/VOC molecules Macropores (>50nm): Create high-speed channels for pollutants Why choose PAC? Three Overwhelming Advantages in Industrial Scenarios 1. Minute-Level Emergency Response Pollution Incidents: Directly apply PAC to polluted water bodies; adsorbs algal toxins (such as geosmin) within 15 minutes. Compared to granular activated carbon: No need to fill filter canisters, saving 2 hours of equipment setup time. 2. Precise Dosage Control Dynamic Dosing: Adjusts dosage in real-time based on pollutant concentration (5-50 mg/L; e.g., 20 mg/L for dye wastewater, decolorization rate >90%). Cost Control: Only 1/10 the investment of a fixed-bed system. 3. Comprehensive Penetration Capability Wastewater Treatment: Degrades recalcitrant COD (biological residual organic matter). Gas Treatment: Captures toluene/formaldehyde (85% removal rate measured in spray painting workshops). Soil Remediation: Fixes petroleum hydrocarbons (3x increase in penetration rate).

The Unsung Hero of Industrial Purity: Kelin Carbon’s Decolorizing Activated Carbon

Few materials are as essential—yet as overlooked—as decolorizing activated carbon. From transforming murky molasses into crystal-clear syrup to ensuring pharmaceutical-grade purity in life-saving drugs, this specialized carbon is the silent force behind countless industries. But what makes Kelin Carbon’s decolorizing activated carbon stand out? And how do we engineer it to tackle the toughest color-removal challenges? Let’s dive in. Get Free Quote What Is Decolorizing Activated Carbon? Decolorizing activated carbon is a highly engineered adsorbent designed to remove color-causing molecules from liquids and gases. Unlike standard carbon—which may focus on small contaminants like chlorine—our decolorizing carbon is optimized to capture large, complex pigments, ensuring unmatched clarity in final products.   How Kelin Carbon Optimizes for Maximum Decolorization Not all activated carbons are created equal. The best decolorizing carbons require:   1. Premium Raw Materials Hardwood-Based Carbon – Ideal for mesopores (2-50 nm), perfect for trapping mid-sized color molecules. Coconut Shell Carbon – Balances micropores (<2 nm) and mesopores, offering both decolorization and general purification. Low-Ash Coal Carbon – Used for heavy-duty decolorization, rigorously washed to minimize impurities. 2. Precision Activation Process We use steam & chemical activation to create the optimal pore structure, ensuring maximum adsorption of pigments like: Melanoidins...
