Submerged Aerobic Fixed Film Technology (SAFF)

We oversee Submerged Aerobic Fixed Film facilities that provide odorless, effective treatment with minimal power and maintenance requirements for homes, businesses, and institutions.

This is a biological treatment method that uses submerged plastic media where bacteria grow and clean the wastewater.

As sewage flows over these fixed biofilms, the bacteria digest the organic matter. The process is simple, efficient, odor-free, and easy to maintain.

  1. Sewage Enters Tank – solids settle in primary chamber

  2. Biofilm Breakdown – aerobic bacteria on plastic media eat the waste

  3. Air Supply – blowers push oxygen into the tank

  4. Settling Tank – clean water separates from sludge

  5. Chlorination or UV – disinfected water exits for reuse or disposal

What is SAFF Technology?

Best Fit For:
  • Apartment Societies

  • Schools & Colleges

  • Government Offices

  • Hospitals

  • Commercial Buildings

  • Industrial Staff Quarters

It's like giving bacteria a “home” where they can live and clean water without moving.

How SAFF Works

  • Daily Plant Operation: We operate the SAFF system day and night, ensuring oxygen levels, water flow, and sludge balance.

  • Bio-Media Monitoring: We inspect the condition of bio-media and check for clogging or growth issues.

  • Blower & Diffuser Cleaning: We regularly clean blowers, valves, and air lines to ensure consistent oxygenation.

  • Sludge Management: Timely sludge removal to prevent overflows, odors, or loss of efficiency.

  • Water Quality Testing: Regular testing of BOD, COD, TSS, and pH levels to ensure compliance with PCB norms.

  • AMC Contracts: We offer full-service Annual Maintenance Contracts for long-term performance with zero hassle.
