Saff Media

AFF is “Submerged Activated Fixed Film Reactor” is a type of aerobic attached growth treatment process. It is principally designed to enhance the efficiency of conventional activated sludge process. The conventional process tanks occupy larger land area, involve constant monitoring of parameters like MLSS & SVI, require continuous power supply and are susceptible to shock loads. SAFF reactor, whereas , needs , less power , lower volume, no recycling of sludge , less footprint area, besides allowing higher loading to make it an acceptable product. With lower sludge generation plug flow design for positive treatment, SAFF reactors help the ETP users do away with a host of monitoring and running costs, making operations of ETPs easier. Besides this, parallel plate separators and tube settlers are products that are today replacing huge solidsludge removal equipment.
The use of structured plastic media with the Activated sludge process helped to reduce the volume of the tanks with increased performance. The SAFF systems can easily fit in to underground basins because of small foot print area hence the system is most useful for Sewage Treatment Plants in crowded cities where space is a constraint.
