Water & Wastewater Reuse Solutions

Recycling wastewater can provide a reliable water source for industry, irrigation, and municipal use

Treating wastewater for reuse has become an accepted and reliable technical solution to address water scarcity problems around the world. Previously considered a disposal liability, reused wastewater can now become a valuable resource.

Fluence has decades of experience around the globe in the advanced treatment of wastewater to purity levels that allow its reuse for industrial, agricultural, or municipal applications. We help our clients optimize their costs and minimize their environmental footprint.

Our energy-efficient solutions for industry can treat wastewater to a quality suitable for reuse in power generation, boiler feeds, cooling systems, beverage bottling, food production, and more.

Recycled treated wastewater can be used for surface irrigation of food crops, orchards and vineyards, golf courses, and landscaping. Other uses include recharging groundwater and preserving or augmenting wetlands or riparian habitats, as well as toilet flushing, street cleaning and other similar purposes.

With the high cost of transporting water, our decentralized wastewater treatment solutions are particularly suited to reuse applications close to the point of use. They provide a cost-effective solution, reduce the need to invest in large infrastructure projects, and help protect the environment.

Our water reuse solutions provide the following benefits, and more:

  • Preserve freshwater resources
  • Postpone or eliminate the need to develop a new water resource
  • Reduce disposal and energy costs
  • Improve visibility of long-term costs of water supply
  • Minimize the environmental impact of wastewater discharge
  • Attract new industry
  • Improve the sustainability of local communities and economy

Fluence also provides zero liquid discharge (ZLD) solutions for municipal, industrial, and commercial applications.

Featured Water Reuse Solutions

Fluence technologies for water reuse are the most advanced in the industry, and provide safe and reliable treated wastewater in compliance with local regulations, customer quality requirements, and industry best practices.

Membrane Aerated Biofilm Reactors (MABR)
Our innovative MABR solutions use passive aeration and biofilm-based nitrification-denitrification to provide primary and secondary treatment, producing treated wastewater suitable for reuse in irrigation. It is particularly suited for decentralized treatment of municipal wastewater. MABR uses up to 90% less energy for aeration than conventional technologies for a significant reduction in operating cost.
Anaerobic Membrane Bioreactors (An-MBR)
Fluence’s latest technology development in anaerobic digestion has focused on anaerobic membrane bioreactors (An-MBR). An-MBR combines anaerobic digestion with MBR technology that replaces centrifuges and dissolved air flotation (DAF) for the concentration of the solid digestate. This technology provides better quality treated effluents that can be reused onsite for industrial applications, and is particularly well-suited for dairy industry wastewater treatment.
Tertiary Treatment for Industrial Reuse
In addition to our primary and secondary wastewater treatment options, Fluence provides additional tertiary treatment solutions for industrial applications, such as process water and ultrapure water, including:

Containerized Water Reuse Systems
Fluence can deliver containerized systems for reuse anywhere in the world, including our NIROBOX™ and EcoBox™ product lines, which provide easy-to-deploy solutions housed in standard 40-foot shipping containers.

  • The Nirobox WW model is a membrane bioreactor (MBR) treatment plant for wastewater reuse.
  • The Ecobox is a tertiary treatment suite that includes pretreatment, UF, RO, advanced oxidation, and disinfection.

Our containerized treatment plants are fully automated and are controlled by our innovative Smart Operation suite, which enables real-time monitoring and response, and optimization of operating expense.

Featured Water & Wastewater Reuse Case Studies

Containerized Blowdown Water Recycling for Solar Power Plant

A utility-scale concentrated solar power (CSP) plant in Israel uses sunlight to produce high-pressure steam to power a turbine generator. Brackish blowdown wastewater, which is continuously discharged on-site, must be disposed of in evaporation ponds unless it's treated for reuse. Our fully containerized solution uses ultrafiltration and reverse osmosis to produce cooling makeup water, and adds second-pass reverse osmosis, GTM degassing, and CEDI polishing to produce ultrapure water for boiler use. For maximum reliability, the system is designed with full duty-standby redundancy, including for the control system.

Produced Water Treated for Reuse at Remote Oilfield

At a remote oilfield in Colombia, we provided a high-recovery produced water treatment and desalination system, with the goal of reuse for irrigation. The multistage, fully automated plant was designed to accommodate approximately 4,000 m3/h (500,000 barrels day) of treated produced water. In order to meet irrigation standards, the treated water had to have a total salinity of less than 240 mg/L, with less than .5 mg/L of hydrocarbons and a sodium adsorption ratio (SAR) of less than 10. The plant is designed to allow 90% of the feed water to be used for irrigation, while 10% (including RO brine) is disposed of via deep well reinjection. Other waste streams from the plant are treated and converted to solid sludge for landfill disposal.

Wastewater Reuse with MBR at Beverage Bottling Plant

FEMSA, one of the largest bottlers in Latin America, had to increase the capacity of the wastewater plant at its Alcorta facility in Buenos Aires, but there was no room for expansion. Fluence addressed the customer's requirements with membrane bioreactor (MBR) technology. A sequential batch reactor (SBR) was converted into a continuous bioreactor with an Airlift membrane clarification step. With the new technology, the treatment plant can handle higher concentrations of sludge, with a smaller footprint than a conventional plant's. The plant produces treated wastewater suitable for reuse within the plant.
