Can Activated Carbon Be Reused?
Activated carbon is widely used in water purification, air filtration, and industrial decolorization due to its excellent adsorption capabilities. However, a common question arises: Can activated carbon be reused? Yes—under proper conditions and with scientific regeneration methods. 1. Is Activated Carbon Reusable? Activated carbon gradually loses its adsorption ability as its pores become saturated […]

Mechanisms of PAC in Organic Removal
As a high-efficiency coagulant, PAC removes organic matter through three primary mechanisms: Charge Neutralization Hydrolyzed Al³⁴⁺ ions neutralize negative charges on organic molecules Adsorption Bridging Forms “organic matter-PAC-organic matter” aggregates Sweep Flocculation Al(OH)₃ precipitates encapsulate organic molecules Typical Treatment Efficiency: -COD removal: 40-85% -Color removal: 60-95% -BOD/COD ratio improvement: 0.2→0.5 (enhanced biodegradability) In-Depth Analysis […]
