The BioSAF is capable of attaining discharge standards of 20 BOD5 : 30 TSS : 5 NH4-N (95%-tile), offering optimised plant performance and provide increased process security.
Performance and Sizing Details
The BioSAF is available in three forms:
- Integral BioSAF Package Plant (30 - 250 PE)
- Modular BioSAF (up to 800 PE, or in multiples up to 3000 PE)
- Custom-Built BioSAF (1000 PE +)
BioSAF Package Plants
BioSAF* Integral Unit
A complete integral treatment process, supplied in GRP cylindrical tank available in a variety of sizes to treat a population equivalent (PE) of between 30 and 250.
The complete treatment process includes three stages of operation, including:
- Stage 1: Screening and grit removal; sludge storage; primary settlement;
- Stage 2: SAF stage for aerobic fixed film biological treatment;
- Stage 3: Humus settlement stage with air lift return to septic tank.

BioSAF Modular Units
BioSAF* Modular Unit
A unit supplied in a rectangular coated or stainless steel tank, designed to be used as part of a separate unit process configuration e.g. PS / SAF / HT, suitable for treating population equivalent (PE) up to 800 or in multiples up to 3000 PE.
It is compact and simple to install with minimal disruption to the existing treatment system. The unit is ideal for upgrading existing works, for treatment at smaller sites or for emergency treatment during plant failure, maintenance or upgrading.

BioSAF Custom Built Units
BioSAF* Custom Unit
The units are designed and built to address specific site requirements and generally suitable for applications with a 1000 population equivalent (PE) upwards.
The units are built with either GCS or concrete tanks and utilise non-clog coarse bubble diffusers or high efficiency membrane diffusers. Like the modular BioSAFTM, the custom-built units are ideal for roughing, secondary, combined secondary or tertiary applications. Robust fixed film technology together with OPEX / CAPEX ensure BioSAFTM technology is the first choice alternative to BAFF or AS systems. BioSAFTM are ideal for treating municipal wastewaters or highly-complex industrial effluents.
