- Model SW - Containerized Seawater Desalination Plant



Containerized seawater desalination solutions ensure water availability in a wide range of applications. NIROBOX™ SW is a modular, high-output, membrane-based and efficient seawater desalination solution that offers pretreatment, reverse osmosis, and post-treatment – all housed in a single, self-contained 40-foot shipping container.

Nirobox SW is suitable for a variety of applications, including desalination for potable or industrial water, and can meet the most stringent regulatory requirements. Offering industry-leading capacity, a single Nirobox SW container can produce up to 1,500 m3/d (275 GPM) of permeate water, making it the most compact plant-in-a-box.

Nirobox SW offers recovery rates of up to 50%. This, along with low chemical and energy consumption, reduces overall operational costs.

Nirobox SW’s patent-pending process includes a cleaning process for the ultrafiltration membranes that inhibits microorganism growth and scaling. This natural disinfecting effect lowers energy and chemical requirements, and minimizes the plant’s ecological footprint. Moreover, Nirobox SW features a work-exchanger energy recovery device with the lowest energy consumption in the industry.

Nirobox SW is designed to treat seawater with total dissolved solids (TDS) between 15,000 and to 45,000 ppm, turbidity of up to 20 NTUs, and oil and grease up to 1.5 ppm. Additional, optional pretreatment processes in the front end like dissolved air flotation (DAF), clarification, and activated carbon filters (AC) will widen the range of feed water quality.

Nirobox SW is offered in three standard models with flow rates of 500 (92 gpm), 1,000 (183 gpm) and 1,500 m3/d (275 gpm). All are housed in one single, pre-engineered, fully assembled and pre-tested 40-foot shipping containers

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

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.
