EFLOSAF Submerged Aerated Filter
The Corodex EFLOSAF is a high rate biological treatment process based on submerged aerated biofilter using a fixed film, with an attached biological growth process. It is designed to achieve a final effluent of 10/10/2 in terms of BOD5/TSS/N-NH3. The high rate biological oxidation process is performed using an extremely efficient Submerged Aerated Filter with a very high specific surface area.
The EFLOSAF process flow entails the following:
- Incoming sewage is lifted by a pump at average flow rate and delivered to the Biozone Submerged Aerated Filter
- Biologically treated liquor discharges from the Biozone to a secondary settlement tank
- Biologically treated liquor gravitates through the final settlement tank
- Final effluent discharges from the settlement tank to a chlorine contact tank
- Treated sewage effluent is filtered via pressure sand filters prior to final discharge or reuse
Advantages of EFLOSAF Submerged Aerated Filter:
- Small foot print
- Low sludge production
- No moving parts
- High efficiency
- Stable high quality effluent of 10 BOD and 10 TSS
