The EfloSAF Submerged Aerated Filter or SAF, is a very compact,
robust and trouble free process ideally suited to package type plants for
communities and labour camps. The process employs a structured, support media
and this forms an ideal place for the biomass to attach itself. The waste water
then passes through the matrix where the biomass consume the organic matter.

The media a non clogging structure, fixed in place and with a very high surface area for the volume it occupies. It sits submerged in the biozone. The water passes through the cross fluted media in a very precise manner, flowing through every part ensuring excellent contact with the biomass. Air in introduced underneath and the media ensures very high oxygen transfer rates, allowing for small air blowers and reduced running costs. After the biozone a standard settlement tank is used to clarify the water of any biomass that has detached itself from the support matrix. The is no requirement for a sludge recirculation system.
