Leachate Treatment for Waste Incineration Plant
Pre-treatment + Anaerobic UASB + MBR + Tubular Ultrafiltration + DTRO/STRO High Pressure Reverse Osmosis
The anaerobic UASB process removes 75% to 90% of COD from leachate.
The MBR consists of:
- A denitrification tank
- A nitrification tank
- An external ultrafiltration system
The MBR targets ammonium nitrogen and remaining COD.
The biologically pre-treated leachate is directed into the DTRO/STRO reverse osmosis system.
The DTRO/STRO system operates at high pressure, achieving a recovery rate of 80% to 85%.
The produced water consistently meets discharge standards.
Leachate Treatment for Landfill Sites
Pre-treatment + Hydrolysis Tank + MBR + Tubular Ultrafiltration + STRO (DTRO) High Pressure Reverse Osmosis
The hydrolysis process primarily enhances the biodegradability of leachate.
The external MBR system includes:
- A denitrification tank
- A nitrification tank
- An external ultrafiltration system
The MBR system removes ammonium nitrogen with a removal rate of 99% and addresses remaining COD in leachate.
The biologically pre-treated effluent is fed into the reverse osmosis system.
The high-pressure DTRO/STRO membrane system achieves a recovery rate of 80-85%.The produced water consistently meets discharge standards.
