What is a vSAF?

vSAF is a biological treatment plant that can be used for both secondary treatment (BOD and ammonia removal after primary settlement tanks) and tertiary treatment (additional nitrification for existing humus tank effluents). It is built offsite which reduces construction time when compared to other on-site build options.

Smaller Footprint

One of the standout advantages of vSAF is its smaller footprint compared to conventional SAF units. This compact design allows for more flexibility in terms of installation, especially in areas where space is limited.

Efficient Oxygen Transfer

Efficient oxygen transfer is crucial in wastewater treatment processes, and vSAF excels in this aspect. Thanks to its vertical design, the unit achieves a remarkable oxygen transfer rate of 5% O₂/m.

Gravity Flow and Tertiary Treatment Integration

Another advantage of vSAF is its ability to allow gravity flow from the top of the unit into other forms of tertiary treatment, such as sand filters, if required.

Reduced Blower Sizes

SAF units require blowers sized according to the surface area (m²) of the media to ensure effective scouring, which removes any dead biomass. This reduction in blower size not only results in cost savings but also contributes to energy efficiency

Wastewater treatment plants can benefit from the versatility and cost-effectiveness of vSAF while achieving optimal nitrification and overall effluent quality. Embracing innovative solutions like vSAF is key to advancing wastewater treatment processes and meeting the ever-increasing demands of environmental sustainability.

The vSAF is an alternative to the conventional SAF and compliments the range for bespoke site applications.
