WAPPSYS OXY BIO Sequential Bio Reactor
We offer next generation Pre-engineered sewage treatment plants based on WAPPSYS OXYBIO (Sequential Batch Reactor - SBR) process. This easy to install STP is a standard engineered package developed through inhouse R&D.
Wappsys Oxybio has many variants from very small plants to very large plants, specific designs and features for hotels, hospitals, townships (modular), Malls (2 shift operation) etc. with prefab tanks etc.
These plants are pre-engineered for capacities ranging from 10 KLD to 1200 KLD and are available in two versions: Fully automatic (premium) version and semi automatic (standard) version. Besides process, automation makes it a simple yet intelligent system. Plants above this capacity are engineered specifically to be delivered as per the site/ client requitements. We have ready design data for 5, 10, 20, 30, 40, 50, 75 & 100 MLD plants having standard specifications which are fully automated with SCADA and can be monitored remotely.

Features
- Activated Sludge process -No clarifiers, media or membranes
- Most Compact & energy efficient, Power consumption – Linear with flow. Leading to huge energy savings in part load conditions
- Modular, with simple/fast construction, Prefab tanks as option-very small to very large plant possible
- Futuristic with nutrient removal options -Semi automatic / Fully automatic. UF for tertiary treatment as option
Comparison of SBR Vs MBR
| SBR | MBR |
| Process is independent of membranes, can be used for post treatment in full or part capacity as per the requirement | Membranes very sensitive to oil & grease, sludge, hair, glass/metals. |
| Plant can be operated in manual mode | Plant cannot be operated in manual mode |
| Most lower energy consumption. Batch process. Blowers don’t need to operate continuously. Huge savings during partial load conditions | Energy intensive, continuous process & thus blowers need to operate continuously. Minimal saving during part load conditions. |
| Lower Capex | Higher Capex |
| Quick commissioning / stabilization periods Plants can be commissioned at low load during the initial start up of any project. | Long commissioning / stabilization times. During initial periods at low loads, plant cannot be commissioned |
| Volumetric space requirement of SBR based plants is lower or comparable | Volumetric space requirement of MBR plants are high, because of free space required for membranes above the tanks |
| No chemical required in the process | Chemicals to be used for membrane cleaning/recovery to retain the efficiency of biological process. |
| Low maintenance, flexible & literally not so sensitive process | High maintenance/sensitive process |
| SBR followed with MF/UF/UV can give comparable water quality at a lower Capex/Opex. | MBR can give very good water quality but at high capex/opex & with the sword hanging on the neck all the time |
| Success rate of SBR based plants on the ground in India is 80-100% | Success rate of MBR based plants on the ground in India is only 5-10% |
