• The main feature of RABAC technology is Bacillus, naturally occurring bacteria discovered over a hundred years ago and used widely today for production of antibiotics.
  • The intrinsic characteristics of Bacillus cells help ingest organic materials, nutrients, and other odor-causing contaminants with high degree of removal efficiency. When stressed, the cells also form endospores that can survive in extreme environment for thousands of years. Acting as natural disinfectants, these endospores produce antibiotics and bactericides that kill other harmful pathogens.

1. Activated Bacillus Suspension (ABS) Process:

- A low cost solution for upgrading lagoon system for nutrition removal.
- Suitable for small scale municipalities and agricultural firms in rural area

2. RABAC Process:

- A low cost solution for upgrading a secondary treatment facility for an advanced treatment facility
- Suitable for large scale municipalities and industries in urban environment.

At the core of the technology is also the RABAC Unit, a bioreactor equipment designed to exploit the Bacillus lifecycle by providing necessary conditions for the bacteria to grow and thrive under widely varying oxygen conditions to enable their perpetual recycling and reuse. The RABAC Unit is made of highly porous reticulated synthetic fiber (polyvinylidene chloride) mesh disc that provides very large surface area and allows high treatment capacity with excellent oxygen and nutrient transfer kinetics.

The Unit also enables a diverse range of biochemical reactions to take place, including aerobic (open air),anaerobic (immersed), and recently discovered biological process known as anammox (anaerobic ammonia oxidation). Anammox process has proven very effective in nitrogen removal and consumes only about 50 percent of the oxygen required by other conventional nitrogen removal processes.
