Wastewater Treatment Solutions
Containerized and customized wastewater treatment solutions for municipal compliance and industrial applications
With more than 30 years of experience in the design, construction, and operation of wastewater treatment plants, Fluence provides solutions that efficiently treat wastewater and ensure regulatory compliance across a range of industries.
Fluence also has decades of experience in tertiary treatment, enabling treated wastewater to be safely reused for irrigation, process water, industrial applications, and potable reuse.
In addition to advanced biological and tertiary treatment, Fluence wastewater treatment plants are equipped with full instrumentation for remote or on-site monitoring of key process parameters. Systems can be fully automated through the Smart Operations suite, enabling real-time performance optimization and lower lifecycle operating costs.
Containerized, Decentralized, and Scalable Systems
In addition to conventional plants, Fluence specializes in decentralized wastewater solutions that are modular, scalable, and quick to deploy.
Fluence combines containerized engineering, scalable modular design, and flexible delivery models to support interim capacity, permanent decentralized treatment, or phased expansion aligned with real growth.
Decentralized wastewater treatment is often the right solution when:
- Centralized plants are at or near capacity
- Plant expansion timelines exceed development schedules
- Service boundaries limit connection options
- Remote locations lack access to sewer infrastructure
- Phased growth requires staged infrastructure
- Industrial facilities need to expand capacity, meet reuse mandates, or upgrade discharge quality without interrupting operations
Decentralized systems can be used for short-term or long-term treatment based on the project’s needs.
Market-Leading Technologies for Municipal Wastewater Treatment
Fluence engineers have developed some of the most efficient and cost-effective municipal wastewater treatment technologies on the market. Here are a few of the proven solutions in our fleet.
Aspiral™ Flex Modular Containerized Wastewater Solutions
Aspiral™ Flex modular containerized wastewater solutions offer a variety of configurations that can be mixed-and-matched for the ultimate in customization. Packaged in standard 20- or 40-foot shipping containers for easy shipping and installation, these systems provide secondary biological treatment through membrane aerated biofilm reactor (MABR) technology, as well as membrane bioreactors (MBR) and conventional activated sludge. Clarifier units and units for equalization and/or sludge-holding and tertiary treatment (ultrafiltration and disinfection) are also available.
These fully containerized, preassembled systems are designed for reliable nutrient removal and regulatory compliance, with a modular configuration adaptable to each project’s specific requirements.
Aspiral™ Flex is an ideal solution for small- to medium-sized plants serving small towns, villages, residential communities, resorts, hotels, commercial complexes, and worker encampments.
A common application for Aspiral™ Flex is lagoon upgrades. Many municipalities rely on lagoon-based wastewater treatment systems that were designed decades ago under less stringent nutrient regulations. As discharge limits tighten, particularly for total nitrogen and phosphorus, Aspiral™ Flex can help bring lagoon plants into compliance without full replacement or major new site requirements.
SUBRE Wastewater Treatment Plant Upgrades and Greenfield Projects
SUBRE uses submerged MABR technology to strengthen both existing wastewater treatment plants and greenfield projects. When a conventional activated sludge facility has reached its limit, SUBRE can improve effluent quality, reduce chemical use, lower energy and operating costs, and increase capacity. The same MABR technology can also be used in greenfield plants, providing a space-efficient, low-energy solution for effective wastewater treatment in a smaller footprint.
Tipton Containerized Extended Aeration Wastewater Treatment Plants
Fluence's Tipton Series prefabricated, containerized wastewater treatment plants provide reliable, complete on-site treatment solutions for municipal and private clients — wherever there's a need for wastewater treatment on a smaller scale.
- Prefabricated containerized plants are available with flow rates from 200 to 350,000 GPD (0.76-1,330 m³/d).
- Field-erected containerized plants have a flow rate ranging from 50,000 to 2 million GPD (189-7,570 m³/d).
Tipton Series containerized plants are flexible, easy to operate in the field, and designed to minimize installation and startup costs. Smaller systems come completely assembled, plumbed, and wired for immediate, low-cost installation and startup.
Industrial Wastewater & Reuse Solutions
Fluence provides industrial wastewater and reuse solutions for facilities facing high-strength organic wastewater, tightening discharge limits, water scarcity, and sustainability goals. Its industrial portfolio includes dissolved air flotation, total nitrogen removal, anaerobic treatment and waste-to-energy systems, digestate aerobic treatment, MABR, shortcut nitrogen removal, industrial reuse tertiary treatment, and aerobic and physico-chemical wastewater treatment.
These solutions support industries such as food and beverage processing, meat processing, mining and lithium production, power generation, and high-tech manufacturing, where compliance, water reliability, and operational continuity are critical. Depending on the application, Fluence can deliver modular systems, retrofit solutions, or custom-engineered plants designed around project-specific treatment goals, site constraints, and long-term operating requirements.
Innovative Delivery & Financing Options
Fluence offers multiple delivery models and financing options:
- Direct ownership: The client purchases and owns the system. Fluence provides commissioning, training, and optional O&M support.
- Build-own-operate (BOO): Fluence finances, owns, and operates the system under a long-term service agreement.
- Service-based and pay-for-performance models: With Water Management Services, clients pay predictable monthly service fees tied to treatment volumes. No large upfront capital expenditure required.
These models reduce compliance risk, preserve capital, and shift operational responsibility where needed, helping municipalities and industries focus on core priorities while maintaining regulatory certainty.
Need expert guidance to determine the best path forward?
Whether you're evaluating options for expanding a wastewater treatment plant, facing capacity constraints, or planning phased development, the Fluence team can help you identify the fastest, most efficient path forward.
What Is MABR?
Membrane aerated biofilm reactor (MABR) technology provides a revolutionary improvement in aerobic wastewater treatment due to its highly efficient nutrient removal and its energy efficiency, compared to traditional wastewater treatment systems.

FAQs about Fluence’s Wastewater Treatment Solutions
How does Fluence determine the right wastewater treatment solution for a specific project?
Can Fluence upgrade existing wastewater treatment infrastructure, or is it only for new plants?
What types of wastewater treatment solutions does Fluence provide?
Who operates and maintains the system?
Fluence offers several delivery models. Under direct ownership, the client may operate the system with optional Fluence support. Under build-own-operate (BOO) or service-based agreements, Fluence is responsible for operations, maintenance, and meeting compliance requirements.
Can Fluence systems support future growth or changing treatment requirements?
Yes. Fluence solutions can be designed to support phased expansion, increased capacity, changing influent conditions, and evolving discharge standards. Depending on the system, this may involve retrofits, process upgrades, or additional treatment capacity over time.
What Is Fluence’s Membrane Aerated Biofilm Reactors (MABR)?
Fluence's patented best-in-class MABR technology provides rigorous wastewater treatment with low energy consumption. Due to passive aeration, MABR consumes up to 90% less energy for aeration than conventional plants. MABR technology enables simultaneous nitrification-denitrification for very high nutrient removal, and uses passive aeration, which is much more energy-efficient than the compressed-air aeration used in conventional treatment.
MABR is available in the Aspiral™ Flex line of containerized wastewater treatment units and SUBRE wastewater treatment plant retrofits or new builds.
