Abstract:Domestic wastewater treatment plants produce large amounts of waste sludge. Sludge can be used to produce activated carbon using potassium hydroxide (KOH) as an activating agent. However, KOH is expensive (relative to the cost of waste carbide lime), making the conversion of waste into valuable products unsustainable. This study explored the utilization of a solid waste by-product, carbide lime waste, as a replacement for KOH to produce sludge-based activated carbon (SBAC). The effects of activation conditions… Show more
