What Is Submerged Aerobic Fixed Film Reactors?
SAFF is an element of a sewage treatment plant's technology.It is an aerobic biological technique that employs corrugated inert UV stabilized PVC material. The Submerged Aerated Fixed Film Technology's increased surface area aids in the quick digestion of biomass by microorganisms. The air is provided using a mechanical aeration system that includes a blower and diffusers in this technique. The SAFF media is supported by a bottom support, which is installed in the fixed reactor with the SAFF media.
In the wastewater sector, Netsol’s range of submerged aerated fixed film (SAFF) technology is the most cost-effective and simple method. It is mostly employed in commercial and residential buildings, as well as in the sewage sanitation industry. This method is most commonly employed when land is scarce and operational staffing is uneconomical. The procedure aids in the reduction of organic load, biochemical oxygen demand (BOD), and Suspended Solids (SS) in domestic and commercial sewage effluent. This method is most commonly used in small to medium-sized treatment facilities.
Working of SAFF Technology
Primary Settlement, Se?condary Treatment, and Final Settlement/Clarification are the three steps of this method.
Primary Settlement: Larger materials sink at the bottom of the primary tank, where they are removed as sludge on a regular basis. Scraping/screening is frequently used to remove other buoyant debris that float higher.
Secondary Treatment: The biomass on the SAFF medium degrades the biodegradable Organic matter in secondary treatment.
Final Settlement/Clarification: The process of settling deteriorated solids out of biologically treated wastewater is accomplished here.
Contaminants removed by Submerged Aerobic Fixed Film Reactor
It reduces the organic loading of sewage/wastewater in both residential and commercial settings. The method reduces Biological Oxygen Demand (BOD) and a large amount of Suspended Solids (SS), which would otherwise pollute rivers and other water outlets if left untreated. To put it another way, the SAFF procedure is utilized to significantly enhance effluent discharge quality.
In the wastewater industry, it is viewed as a simple and cost-effective way of commercial and residential sewage sanitation/wastewater treatment, especially for small to medium-sized treatment facilities with limited acreage and full-time operational manpower. Any serviceable pieces will be positioned such that they may be accessed quickly without affecting the current treatment in a well-designed Submerged Aerated Plant.
Key Features of SAFF Technology
1: Essentially a fixed film medium with subsurface aeration to increase oxygen delivery.
2: When compared to stone and aggregates, unconventional plastic media has a high void ratio and specific area.
3: Large biomass and long solid retention time in the reactor leading to low ‘food to micro-organism ratio’ and higher organic removal.
4: Two stage biological oxidation.
5: Treatment scheme excluding primary sedimentation and sludge digestion.
6: Reactors up to 6 m deep enabling low land requirements.
7: Tube settlers offer space economy.
