TJB Coal Power Plant Seawater Desalination Pretreatment Using Granular Activated Carbon

The project involves the treatment of high-strength wastewater generated from the backwash cycle of a seawater reverse osmosis (SWRO) pretreatment system at a coastal coal-fired power plant. The water contains elevated levels of suspended solids and organics, including humic substances and low-molecular-weight acids. Granular activated carbon (GAC) filtration was integrated downstream of physical clarification to further reduce organic loading and improve SDI stability.

• Carbon Type: High-iodine GAC, coconut shell origin, mesh size 8*30
• Filtration Mode: Gravity-fed media filtration
• Post-treatment use: Reuse within plant or discharge to marine environment

• Significant reduction in membrane fouling risks
• Extended membrane cleaning cycles and improved system uptime
• Stable operation during seasonal water quality fluctuations
