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.
