TETRA - Submerged Aerated Filters (SAF)
From Filtration Systems
The TETRA SAF submerged aerated filters are a simple process for the biological oxidation of ammonia-nitrogen (NH3-N) and BOD for both municipal and industrial wastewaters. TETRA SAF is an upflow, fixed-film biological reactor that uses coarse media requiring no backwashing.
- Exceptional performance, reliability, flexibility
- No backwashing required
- Small footprint
- Low operational and maintenance cost savings over competitive systems.
- A robust, small footprint system
- Can be used for either secondary treatment (SAF/cSAF) or as a tertiary (nitrification) stage (NSAF)
In addition, the TETRA Nitrifying SAF (NSAF), is a robust solution, based on established TETRA SAF technology for tertiary ammonia removal. The up-flow, fixed film biological system represents a simple, proven and cost effective way of achieving ammonia standards down to as low as 1 mg/l on a 95 percentile basis.
