Aspiral uses MABR technology in modular containers for effective, scalable, and sustainable wastewater treatment in a small package

Aspiral is a smart wastewater treatment solution that packages Fluence’s innovative membrane aerated biofilm reactor (MABR) technology in standard shipping containers. This modular solution produces a very high quality effluent and reduces energy usage for aeration by up to 90% compared to conventional methods.

Aspiral is an ideal solution for small- to medium-sized plants serving small towns, villages, residential communities, resorts, hotels, commercial complexes, and more. Aspiral's efficiency makes it suitable for decentralized treatment off the grid since its low energy needs can be supplied by alternative sources.

The Aspiral line offers several model sizes and configurations, with treatment capacities starting at 20 m³/d, depending on the effluent requirements. Several containers may be connected in parallel to handle large quantities of effluent. For operating ease, the systems can be remotely monitored and controlled with our Smart Operations suite.

Smart Packaged Wastewater Treatment Technologies

Aspiral containers each feature from one to five MABR units. MABR treats wastewater with a spirally wound membrane envelope submerged in a tank. Passive aeration takes place with air pumped into the membrane at near-atmospheric pressure. A biofilm that forms on the membrane is responsible for a simultaneous nitrification-denitrification process that produces a high-quality effluent that meets California's Title 22 standards for water reuse, China's Class 1A and IV standards, as well as many other national and regional effluent requirements.

All process units -- for example, the mechanical screen and secondary clarifier -- are customized for each installation, and the plumbing between the main process units is installed onsite.

Pretreatment includes fine (1 mm) screening, which is followed by oil and grit removal if required. MABR treatment removes up to 90% of Total Nitrogen (TN) and Total Phosphorous (TP). Chemicals are used only when additional removal is required.

Tertiary treatment such as filtration and disinfection are compatible with the process and can be provided separately.

The Benefits of Aspiral™

• High Effluent Quality
  MABR's efficient nutrient removal produces high-quality water suitable for use in irrigation or discharge into the environment.
• Simultaneous Nitrification and Denitrification
  A biofilm that forms on the spirally wound membrane supports simultaneous nitrification-denitrification (SND) for high nutrient removal.
• Low Maintenance and Operation Costs
  Aspiral's simple design means low maintenance and operation costs, and the systems can be remotely operated and controlled. The MABR technology also reduces the need for added carbon.
• Energy Efficiency
  Fluence's MABR modules use low-pressure passive aeration, which reduces the energy used for aeration by up to 90%. This low energy consumption allows for decentralized treatment off the power grid.
• Low Odor and Noise
  Using passive aeration not only saves energy, but it also lowers levels of noise and odor for neighborhood-friendly operation.
• Flexibility and Scalability
  Fluence Aspiral MABR solutions are available as decentralized, scalable, easily portable systems packaged in standard shipping containers.
