Dual denitrification, sand filtration, water reuse loop, sludge separation

Challenge

• Treating complex wastewater from dredged silt filtration
• High levels of fine suspended solids and nitrogen compounds
• Need for reliable effluent quality to meet strict discharge limits
• Integration of multiple treatment steps in a compact system
• Partial reuse of effluent as process water

Result

• Efficient removal of COD, nitrogen, and suspended solids
• Compliant effluent quality suitable for discharge and reuse
• Stable biological operation with optimised nitrogen removal
• Reduced environmental impact of dredging activities
• Operational flexibility and process water recovery within the site
