With low energy consumption and minimal maintenance, Aspiral™ Flex delivers superior performance and long-lasting reliability to meet the needs of small to medium-sized communities and facilities.
Decentralized design is customized to suit treatment needs
As demand grows for sustainable wastewater solutions, the Aspiral™ Flex line from Fluence stands out with its versatile, containerized wastewater treatment units. Ideal for small- to medium-sized communities and facilities, the Aspiral™ Flex units can handle flows from 5,000 to 250,000 gallons per day (20 to 950m3 per day), serving populations of 50 to 3,000 people. The modular, decentralized design is well-suited for diverse locations such as rest stops, condos, hotels, RV parks, and many more.
Modular Design and Diverse Options
The Aspiral™ Flex units are structured for maximum customization with configurations to suit specific treatment needs. Units can stand alone or integrate seamlessly into existing wastewater treatment designs. Options within the Aspiral™ Flex line include:
- Aspiral™ S and Aspiral™ M: These all-in-one biological treatment units feature a fine screen, activated sludge or membrane aerated biofilm reactor (MABR), a secondary clarifier, disinfection, and for the Aspiral™ M, optional tertiary treatment.
- AspiralTM EQSL: The equalization/sludge holding unit features a fine screen, decanting mechanism, and coarse bubble diffusers powered by an external blowing skid.
- AspiralTM Bio: The biological treatment unit features activated sludge or MABR with a low dissolved oxygen basin powered by an external blowing skid.
- AspiralTM UF: The ultrafiltration unit provides a fine screen, 1-4 membrane cassettes, disinfection, auxiliary operation tanks, pumps, and blowers.
- AspiralTM Clarifier: The clarifier unit includes secondary clarification, optional tertiary treatment, and disinfection.
As an example, an Aspiral™ Flex plant configuration might include three equalization units, three biological treatment units, and one ultrafiltration unit for an Aspiral™ MBR plant that provides efficient wastewater treatment and discharge.

The Power of MABR Technology
Central to the Aspiral™ Flex line is the MABR technology. This unique biological process simultaneously removes biological oxygen demand, total nitrogen, and total phosphorus in a single pass. MABR’s passive aeration reduces energy use by up to 90%, cutting operational costs while providing an efficient treatment solution.
The Aspiral™ Flex units containing MABR (Aspiral S, M, and Bio) deliver impressive pollutant removal rates:
| Pollutant | Typical Influent | Typical Effluent | Removal Rate |
|---|---|---|---|
| Ammonia (NH4N) | 45 mg/L | <3 mg/L | >93% |
| Total nitrogen | 55 mg/L | <5 mg/L | >90% |
| Total phosphorus | 10 mg/L | <1 mg/L | >90% |
| Total suspended solids | 350 mg/L | <10 mg/L | >93% |
| Biological oxygen demand | 300 mg/L | <10 mg/L | >96% |
| Chemical oxygen demand | 600 mg/L | <70 mg/L | >88% |
Additional Benefits of Aspiral™ Flex
- Efficient installation: Pre-engineered and factory-tested, the units are delivered in standard 20- or 40-foot containers for rapid deployment.
- Low maintenance: Durable MABR membrane materials have a life expectancy of more than 20 years, lowering maintenance needs and total cost of ownership.
- Environmental resilience: Designed for adaptability, the units withstand flow and temperature fluctuations.
- Energy savings: Aspiral™ Flex units operate at 0.25 kWh/m³ of biological energy consumption, representing significant savings over conventional treatment methods.
