The Science Behind Sludge Reduction: Understanding the Nebula® Multi-Stage Biofilm System

Are you experiencing excess sludge in your wastewater treatment process? Traditional secondary treatment systems often yield significant biomass production, which presents operational and economic challenges.

Aquarius Technologies offers a solution: the Nebula Multistage Biofilm System. This system utilizes a controlled biological succession within the biofilm to reduce sludge production by up to 70%.

The Science Behind Sludge Reduction

The Nebula system employs a unique, multi-stage approach, fostering a thriving biofilm ecosystem where more significant and efficient organisms consume biomass from previous stages. This self-sustaining food chain minimizes excess sludge, transforming what was once considered waste into a vital component of the treatment process.

Here’s a glimpse into the microbial succession within the Nebula system, which is an example taken from an active installation:

  • Stage 2: Filamentous bacteria rapidly consume soluble organics, forming the foundation of the biofilm.
  • Stage 4: Stalked Ciliates filter-free bacteria, enhancing water clarity.
  • Stage 6: Flagellates graze on smaller organisms, further reducing particulate matter.
  • Stage 8: Rotifers control algae and consume bacteria and particulate matter.
  • Stage 10: Gastrotrichs reduce biomass and compact sludge.
  • Stage 12: Vorticella enhances effluent quality by consuming lower trophic levels.

Benefits of the Nebula® System:

  • Significant Sludge Reduction: Achieve up to a 70% reduction in excess sludge, resulting in lower disposal costs.
  • Operational Simplicity: A self-sustaining food chain minimizes the need for chemical additives.
  • Economic Advantages: Reduced sludge handling and disposal translate to substantial cost savings.
  • Sustainable Solution: Employs natural biological processes.
