Within the wastewater industry submerged aerated filter (SAF) technology is seen as the simplest and most cost effective method of treating domestic and commercial sewage / wastewater, particularly for small to medium sized treatment plants where available land is limited, and where full time operational manning would be uneconomical.

A well-built SAF plant has no moving parts within its main process zones, and any serviceable items will be easy to access without disrupting the ongoing treatment process.

  • Predictable performance
  • Lower operation and maintenance costs
  • No interruption to process
  • Better whole life cost
  • Easy installation

The small footprint design of an ECO-SAF plant allows for reduced plan requirements when compared to other types of treatment process.

This means that existing treatment works which only have basic primary / decant facilities can easily be upgraded without the acquisition of additional land, and that failing plant can often be retro-fitted by using some of the existing facilities, eg the primary stage of an RBC.

ECO-SAF units can be provided in a range of materials to suit an application; stainless steel and GRP are most often used.
