OxyO Technology | Suspended Growth Process |
Cell viability 3 times that of suspended growth process. | Consortium of bacteria grown in suspended growth has high rate of mortality. Aerobic bacteria very sensitive to variation in flow or BOD. |
Sludge production low compared to any other process. | Only extended aeration process produces digested sludge. |
No requirement of seeding bacteria to stabilize the plant. | Need to inoculate with sufficient consortium of bacteria to start the plant. |
Maintenance cost reduced up to 90-95% | High maintenance cost |
No chemicals used | Chemicals & filters may be used |
