Wastewater Treatment
Fluence wastewater treatment solutions are comprehensive, from aeration and mixing solutions to extended aeration, and our latest state-of-the-art membrane aerated biofilm reactors (MABR). Our MABR solutions are poised to become the next generation of wastewater technologies around the world, enabling a reduction of energy consumption of up to 90% for aeration.

Fluence has extensive expertise and references in wastewater reuse applications. Our tertiary treatment suite can process treated wastewater for reuse in irrigation, grey water, industrial use, and many other applications.

Our wastewater treatment solutions include:

  • Aeration
  • Sedimentation
  • Conventional activated sludge process
  • Biological nutrient removal
  • Anaerobic digestion
  • Tertiary filtration
  • Water reuse
  • Disinfection
  • MABR
  • Membrane bioreactors (MBR)
  • Moving bed biofilm reactors (MBBR)

Decentralized Municipal Treatment Technologies

Here are a few of the technologies that make Fluence a go-to provider of municipal water and wastewater treatment solutions.

MABR Wastewater Treatment
Our best-in-class membrane aerated biofilm reactor (MABR) technologies provide the most advanced, cost-effective wastewater treatment in the industry, with power consumption for aeration up to 90% lower than with traditional methods. Fluence's MABR technology allows for simultaneous nitrification-denitrification and uses passive aeration, which is much more energy-efficient than the compressed-air aeration used in conventional treatment. MABR's low power consumption makes it ideal for use in decentralized plants.
NIROBOX™ for Desalination
Fluence's NIROBOX™ is a state-of-the-art, plug-and-play water treatment plant housed in a standard 40-foot shipping container. It's designed to supply high-quality drinking water or process water from any source. Our Nirobox range is standardized for brackish and seawater desalination, or treatment of surface water. They are designed to maximize production capacity and minimize footprint, with low operational and maintenance requirements.

Fluence's Nirobox is the most cost-effective solution to meet drinking water or process water needs for communities and businesses.

Tipton Packaged Wastewater Treatment Plants
Tipton Series complete packaged wastewater treatment plants are robust, proven, and cost-effective prefabricated plants for on-site treatment. These extended aeration activated sludge plants are designed to treat domestic wastewater, providing an excellent quality of effluent for discharge or for reuse applications. Typical Tipton packaged plants include screening, flow equalization, aeration, clarification, sludge digestion, and effluent disinfection. All systems require minimal final assembly for immediate operation. Construction for our standard package plant is based on prefabricated carbon steel tanks properly coated for long-term exposure to wastewater.

Featured Municipal Treatment Applications

Rural Communities

Small towns, housing developments, resorts and villages tend to have less consistent day-to-day wastewater flow than cities, yet these end users still require high-quality wastewater treatment. Because piping and pumping wastewater to centralized plants in nearby cities is expensive and isn't energy-efficient, many rural communities struggle with inadequate or aging wastewater treatment systems.

Whenever possible, it's economically efficient and sustainable to treat wastewater locally and reclaim it for irrigation or return it to nearby lakes and rivers. A low-cost, decentralized system allows rural villages and small towns to treat sewage from homes and businesses near the source, rather than collecting, storing, and transporting it for treatment.

A quiet, odorless, concealed decentralized plant is the most sustainable solution for rural villages and small towns. Fluence offers innovative wastewater treatment solutions that are energy-efficient, robust and reliable, and that deliver a high-quality effluent. These solutions are cost-effective, easy to operate, and can be monitored remotely.

Effluent reuse for irrigation is a significant component of the integrated management of water resources. It replaces a portion of the water extracted from rivers and reduces the amount of pollutants discharged into our waterways.

Reusing treated wastewater ensures a reliable water source independent of seasonal drought and weather variability, and covers peaks in water demand. This continuous water supply lowers the risk of crop failure and lost income.

Nutrients in wastewater can be exploited to reduce the need for additional fertilizers, resulting in environmental benefits and savings for farmers, and a lower investment for further wastewater treatment.

For rural communities, decentralized treatment is:

  • Cost-effective
  • Quiet, odorless, and easily concealed
  • Simply operated and remotely controlled
  • An independent water resource for irrigation or reuse

Housing Developments

Creating a new neighborhood or residential development typically involves laying expensive pipe mains and building pumping facilities to transport sewage to a centralized city treatment facility. In many cases, this involves re-engineering and retrofitting the main pipes and treatment plant to cope with the increased capacity.

Treating the wastewater in a decentralized treatment plant makes economic and ecologic sense. Fluence's MABR, a fully automated and odorless treatment solution, is a perfect fit for new developments. A local MABR treatment facility can turn wastewater into a new source of quality water suitable for irrigation.

Many residential developments wastefully use drinking water for landscaping, irrigation of parks and playgrounds, as well as for central heating and cooling systems.

A packaged plant can be installed to treat residential sewage for 500 to 5,000 families. It can operate for months with minimum supervision, saving on operational costs while supplying high-quality nonpotable water for landscaping and irrigation use.

Benefits include:

  • Savings on energy and water costs
  • Savings on construction of water mains
  • Compliance with treatment regulations
  • Reduced environmental footprint
