Effluent requirements
The Moving bed™ biofilm process is designed to reduce the organic load to the existing treatment system.
Results
| Parameters | Influent (mg/l) | Effluent (mg/l) | Reduction (%) |
|---|---|---|---|
| COD | 2 140 | 241.4 | 89 |
| BOD7 | 1 196 | 61.0 | 95 |
The Moving Bed™biofilm system has shown a very consistent removal of total organic carbon (TOC) of>60%.
The system handles large swings in organic loads from day to day, and requires minimal operator attention.
