Vertical Submerged Aerated Filters

Smaller Footprint.
Very efficient oxygen transfer due to depth. (5% O2/m)
Allows gravity flow from the top of the unit into other forms of tertiary treatment i.e. sand filters if required.
SAFF blowers tend to be sized on surface area for media scouring purposes and the lower surface area will result in lower blower sizes.

What is a vSAFF?

V-SAFF is a tertiary treatment plant used to achieve additional nitrification for existing humus tank effluents. It is built off-site which reduces construction time when compared to other on-site build options.

The V-SAFF is an alternative to the conventional SAFF units we already build and compliments the range for certain specific site applications.
