BioSAF™ Custom Build Units

Aerobic effluent treatment

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 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.
