- Model BW - Containerized Brackish Water Desalination Plant



Nirobox BW lets you tap into previously unusable groundwater sources.NIROBOX BW is a modular, highly efficient desalination solution for brackish water. It delivers potable water, industrial process water, and high-quality water for irrigation and other applications.

Designed for flexibility, Nirobox BW treats water from a wide variety of sources, including surface water, groundwater, and well water, and can handle turbidity, salinity, and a wide range of contaminants, from 1,000 to 10,000 ppm total dissolved solids (TDS).

Two cost-effective models are available to meet your water treatment requirements and deliver high-quality results:

Nirobox BW LP is designed to operate with feed water containing up to 3,700 ppm TDS
Nirobox BW HP can handle TDS of up to 10,000 ppm

Each is available in three feed capacities: 1,000, 1,500, and 2,000 m3/d. Output water capacity depends on recovery and water-feed specifications. All options are housed in a single, self-contained 40-foot shipping container.

Nirobox BW offers recovery rates of up to 90%, while boasting low chemical and energy consumption.

Nirobox BW’s patent-pending process includes a cleaning process for membranes that inhibits microorganism growth and scaling. This natural disinfecting effect lowers energy and chemical requirements and minimizes the plant’s ecological footprint.

Nirobox BW is ideal for a wide variety of applications, delivering the reliability and robustness needed to meet the operational requirements of municipalities, industries, commercial users, power plants, hotels and resorts, and others.

Fluence provides supervision of erection, start up and commissioning, operator training, full operational and maintenance support/contracts. Contact Fluence to learn more about Nirobox brackish water desalination, or to discuss your next project with our experts.

Standard NIROBOX™ BW units include:

  • Disc filters pretreatment
  • Ultrafiltration (UF) pretreatment
  • Brackish water reverse osmosis (SWRO) – rated 300 psi.
  • Positive displacement high-pressure pump
  • Variable frequency devices (VFD)
  • PLC-based HMI with remote monitoring
  • Mobile app
  • IP-54 MCC
  • Clean-in-place (CIP) system

Optional pretreatments include dissolved air flotation, multimedia filtration, activated carbon filtration, clarification, and post-treatments include remineralization, pH adjustment, and ultraviolet or chlorine disinfection.

Leading the way in water, wastewater, and reuse treatment solutions, Fluence believes that everyone – everywhere – deserves access to clean water. There is no cost-effective technological reason that individuals, communities, or industries should experience water scarcity.

The NIROBOX™ family of solutions challenges convention by providing advanced treatment technologies in affordable and compact packages. Nirobox offers the industry’s smallest overall footprint, which makes the units ideal for the industrial, municipal, and commercial markets.

With models for desalination of seawater and brackish water, and models for treatment of fresh water and wastewater, the Nirobox line of products will provide a suitable solution to your needs.

Nirobox streamlines the economic, environmental, and logistical challenges associated with large-scale desalination and centralized water treatment plants. Nirobox offers flexible, affordable solutions with minimal environmental impact at the most competitive cost available.

Nirobox modular solutions are ideal for:

  • Municipalities and growing communities
  • Housing developments
  • Construction sites
  • Commercial establishments
  • Resorts, hotels, and golf clubs
  • Remote oil and gas facilities
  • Power plants
  • Agriculture irrigation
  • Mining camps and operations


NIROBOX treatment units are available in a number of configurations to suit your site’s size and capacity requirements, allowing fast integration, commissioning, and operation.

Nirobox building blocks are modular and can be adapted to your requirements, providing an independent solution on virtually any scale, from single, self-contained units to large water and wastewater treatment plants.


We offer NIROPLANT and NIROSITE installation options when large-capacity solutions are required.

Niroplant and Nirosite are the ideal solution for decentralized water treatment plants, where ease of operation, lower capital costs, fast delivery and a modular approach are required.

Economy and Efficiency
Our preassembled Nirobox plants are housed in standard shipping containers and are ready to go. They’re engineered for fast deployment, as well as simple operation and maintenance. They also integrate the most energy-efficient components available.

Flexibility and Scalability
Due to smart pre-engineering and design, Nirobox is ready for integration with other systems and equipment. It is completely modular, allowing for capacity upgrades if required. Multiple pre-engineered configurations are available, enabling fast delivery, integration, commissioning, and operation.

Low energy consumption and chemical use reduce the environmental impact of Nirobox plants. The boxes’ unique, patent-pending design provides a unique configuration of low-energy membranes, positive displacement high-pressure pump, work exchanger energy-recovery device, and variable frequency device (VFD). The Nirobox is the lowest carbon footprint desalination plant in its class.

Nirobox’s modular containers can be easily moved for redeployment or resale should your water treatment needs change.

Compact Size
Nirobox’s compact footprint minimizes site impact, lowers the cost of site development, and ensures easy expansion.

Operational Intelligence
Nirobox’s operating systems are fully automated, and remotely monitored and operated, which allows optimization of flow rates, chemical consumption, energy consumption, and more. Our smart design keeps ongoing equipment, operation, and maintenance expenses in check. Data and reports are easily accessible from anywhere on any platform. Real-time alerts can be sent for system malfunctions or abnormal performance.
