Submerged Aerobic Fixed Film (SAFF)

SAFF technology is a procedure used to lessen the organic loading of residential and commercial sewage or waste water, and in doing so will cut the biological oxygen demand (BOD) and a significant quantity of suspended solids (SS) which if otherwise in crude form would contaminate river and sea outfalls, in other words it is used to substantially improve effluent expulsion quality. As with outmoded sewage treatment, SAFF technology uses three stages of dealing with commercial and residential sewage or wastewater. No sludge re-circulation is required to maintain mixed liquor suspended solids (MLSS) as in the case of conventional aeration system. It can be designed to any size to deal with larger flow and loads. Fine bubble diffused aeration used generally reduces the energy requirements as compared to surface aerators. Its modular design allows easy installation. The tank does not need to be drained for access to the diffuser or media. SAFF system takes higher shock loads without reducing the plant performance because of large quantity of biomass available in the reactor. SAFF also supports low sludge generation, low odor and low visual impact. Solids retention time (SRT) can vary based on in-fluent flow without negative process impact. Its most imperative feature is its modular expand-ability and is less susceptible to upsets due to flow variations. It is a simple, yet sophisticated design with simple maintenance requirements. This package includes design, installation, service maintenance with one-year warranty and the AMC (Annual Maintenance Contract) can be renewed annually.
