Sogama Landfill
To treat the raw leachate from a Spanish municipal solid waste landfill, the following treatment layout has been installed at the Client’s site:
- flow equalization and pH adjustment
- pressurized multimedia granular filtration
- anti-scalant dosing
- cartridge filtration
- CD-RO membrane filtration (first pass)
- spiral-wound membrane filtration (second pass)
- ammonia stripping
mft CD-RO modules are essential to be able to cope with the very high organics contents (up to 22,000 mg COD/L)
| Parameter | Unit | Inlet | Outlet |
| Flow | m³/d | 448 to 491 | 218 to 296 |
| COD | mg/L | Up to 22,000 | < 150 |
| Conductivity | mS/cm | 29 to 44 | < 0.6 |
| Flux at operating temperature | LMH | – | 11 to 14 |
| Recovery rate | % | – | 46 to 62 |
| Salts rejection rate | % | – | 95.9 to 99.7 |
| CD module pressure loss | bar | – | 1.7 to 3.5 |
