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.

BioSAF™ Package Plants

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.
Lab Equipment

BioSAF™ Modular Units

A unit supplied in a rectangular coated or stainless steel tank, designed to be used as part of a separate unit process configuration, suitable for treating population equivalent (PE) up to 800 or in multiples up to 3000 PE.
Aerobic Wastewater Treatment

BioSAF™

Submerged Aerated Filter (SAF) technology was introduced by Veolia over two decades ago, and has been continually developed to include units to treat both municipal and industrial wastewater from 30 population equivalent (PE) upwards.
