What is SAFF technology?
The Submerged Aerobic Fixed Film Reactor (SAFF) is a low-cost waste water treatment and sewage sanitation system that is mostly employed in residential and commercial buildings. The procedure aids in the reduction of organic load, biochemical oxygen demand (BOD), and suspended solids (SS) in residential and commercial sewage effluent. The SAFF method is an aerobic biological process with connected growth that employs corrugated inert UV stabilized PVC substrate. Unlike other aerobic suspended growth techniques, it has a greater mechanical surface area due to corrugation on the media surface. This increased surface area aids biomass bacteria in the fast digestion of biomass.
What is the use of SAFF technology?
SAFF Technology is widely utilized in the wastewater sector for commercial and residential sewage sanitation/waste water treatment, particularly for small to medium flow needs. The process air is provided by a mechanical aeration system composed of a blower and diffusers.The reactor's structured SAFF media is held in place by a bottom support system.
This method focuses largely on three stages: primary settlement, secondary treatment, and final settlement/clarification.
1. Primary Settlement: Where heavier particles settle to the bottom of the primary tank and are removed as sludge on a regular basis, and where other buoyant material that floats upwards is normally removed by scraping/screening.
2. Secondary Treatment: The biodegradable Organic Matter on the SAFF medium is decomposed by the biomass.
3. Final Settlement/Clarification: The separation of deteriorated solids from biologically treated effluent.
The Benefits of the SAFF Process
- The MLSS concentration is substantially greater than what is generally attained in the ASP process's aeration system.
- Higher BOD loading on the medium allows for a smaller aeration tank capacity. When compared to the activated sludge process, SAFF requires 25-40% less tank volume.
- The cross-corrugation design of the media guarantees that the air bubble moves in a zigzag manner, enhancing the bubble travel route and consequently the oxygen transfer rates.
- Because of the massive amount of MLSS accessible inside the reactor, the SAFF system can withstand larger shock loads without affecting plant operation.
- In most cases, the rate of sludge formation is lower than in a traditional system.
- The SAFF system has a long life (approximately 10-15 years) due to the use of inert PVC media material. The system is not pressurized.
- This procedure is a variation of the activated sludge process that has overcome its limits.
- All of these processes result in higher-quality treated wastewater.
- Easily satisfies discharge requirements.
- Odour and maintenance issues are no longer an issue.
- High MLSS - Requires less space for treatment.
- The SAFF technique may reduce BOD by 95-98 percent.
Because of the benefits listed above, the SAFF method is often utilized in packaging systems where compactness of treatment is critical.
SAFF Technology's Limitations
1. It necessitates highly skilled personnel.
2. The reactor may become blocked as a result of the lack of initial sedimentation.
3. The greatest dependence is placed on proprietary filter media.
4. SAFF necessitates a substantial reliance on external energy output.
