Decentralized Water & Wastewater Treatment

Fluence has a full line of decentralized treatment solutions, from its robust line of containerized and packaged plants, to the latest MABR units

Fluence is a global leader in decentralized water and wastewater treatment solutions for the municipal, industrial, and commercial markets, with decades of expertise developing and implementing state-of-the-art decentralized treatment using our innovative and cost-efficient technologies for the benefits of customers across the globe.

By definition, decentralized systems convey, treat, reuse, or dispose of water or wastewater close to the supply point or source of generation. Decentralized water or wastewater treatment can be an ideal solution for a variety of public or private buildings or sites, including:

  • Small communities
  • School campuses
  • Malls
  • Resorts
  • Golf courses
  • Industrial plants
  • Mining, or oil and gas camps
  • Construction sites

It makes sense to choose a decentralized solution when there are limited alternatives, for instance, in remote areas; and when the cost of building delivery infrastructure to a centralized facility is higher than building a decentralized facility with a local network. Decentralized solutions also mean easier permitting, faster implementation, and reduced operating costs.

Fluence can deliver its decentralized treatment solutions as a turnkey project, as well as through attractive leasing and financing options. Please check our project financing page for more information.

Market-Leading Decentralized Treatment Technologies

Our decentralized solutions include a range of containerized, pre-engineered, prefabricated, and packaged water and wastewater treatment systems.

Decentralized Water Treatment
Our NIROBOX™ product line features modular desalination, and water and wastewater treatment facilities installed in standard 40-foot shipping containers. The self-contained units are plug-and-play, easy to deploy, and more cost-effective than conventional plants. Larger plant capacity can be achieved by combining containers.

Nirobox can be used for seawater and brackish water desalination, removing contaminants from fresh water, and for the production of drinking, process, and ultrapure water.

The plants can be up and running in less than four months from receipt of the purchase order.

Decentralized Wastewater Treatment
For municipal wastewater treatment, our membrane aerated biofilm reactor (MABR) product line is particularly suited to decentralized settings. Our products are pre-engineered and preassembled, and can be up and running in record time.

Our innovative MABR technology integrates a natural nitrification-denitrification process and passive aeration, which uses up to 90% less power than conventional aeration technology. MABR treatment produces effluent suitable for environmental discharge or irrigation.

We can also deploy our highly successful Tipton plants, which are proven and robust extended aeration packaged plants for municipal, commercial, and industrial applications. Fluence has dozens of reference sites using Tipton wastewater plants.

Decentralized Treatment for Reuse
The Fluence EcoBox™ is a tertiary treatment suite housed in a 40-foot shipping container. It includes pretreatment, ultrafiltration, reverse osmosis, advanced oxidation, and disinfection. Our Ecobox product takes secondary effluents and produces process water or ultrapure water for industrial and commercial use.

Our plants are fully automated and are controlled by our innovative Smart Operation suite, which features real-time monitoring and response, as well as optimization of operating costs.

Cost-Effective Treatment Solutions Delivered Anywhere

Featured Decentralized Treatment Case Studies

NIROBOX™ Desalination Plant in Africa

A high-output desalination plant was urgently needed to solve an acute potable water shortage on the parched southeast coast of Africa. Fluence supplied to Connority, Cyprus 10 NIROBOX™ modular, containerized seawater desalination units to produce 10,000 m3/day of potable water, the 10 NIROBOX™ supplied in just four months.

NIROBOX™ SW for a Costa Rican Resort

Due to an ongoing drought, a beach resort, golf course, and spa in Costa Rica was facing water scarcity. It needed a solution with a high recovery rate that featured low energy consumption and minimal use of chemicals. The system had to be quiet, have a small physical footprint, and a low ecological impact. Three Nirobox units were installed, with a total treatment capacity of approximately 1,500 m3/d, providing disc filtration, ultrafiltration, seawater reverse osmosis, and remineralization to drinking-water quality. The system was started up only eight months after it was ordered, with a plan to gradually increase reliance on the system with the approach of tourist season.

MABR Wastewater Treatment in the US Virgin Islands

The Bordeaux area of St. Thomas needed a wastewater treatment plant to replace an old one that didn't meet environmental regulations or industry standards. An MABR plant was designed, delivered, and started providing high-quality effluent within seven months. It currently provides economical wastewater treatment for 200 homes, and can be easily expanded if required. The plant's quiet, odorless performance was important on the island, which relies on tourism.
