Entex’s fixed film media modules can provide SFF upgrades in aerated tanks and lagoons and can be quite beneficial for industrial pretreatment. SFF eliminates the need for clarifier solids inventory management while providing high-rate treatment. The key difference from IFAS is the lack of a return activated sludge line (RAS), eliminating the suspended growth biomass. Fixed media means easy, quick and inexpensive installation. When you are ready to expand, addition of modules is also both effective and affordable.

SFF features

• attached growth biomass only
• fast and inexpensive installation
• enables pre-treatment without clarifier

Applicable technologies:

• WavTex (modular fixed-film media ideal for aerated tank and lagoon upgrades)
• Webitat (compact fixed-film system designed for flexible retrofits and pretreatment)
• Solar WavTex (energy-efficient fixed-film treatment powered by solar operation)
• Biobloc (self-contained fixed-film modules optimized for industrial and decentralized applications)
