Creating Seawater Desalination Systems with Pre-Engineered Building Blocks


Creating Seawater Desalination Systems with Pre-Engineered Building Blocks


NIROFLEX's flexibility allows for a solution custom-fitted to your needs

With a series of standardized units for pretreatment filtration and reverse osmosis desalination -- as well a range of optional features -- Fluence can quickly and economically build a desalination plant that fits your requirements for capacity and water quality.

Fluence has a proud history of providing water and wastewater solutions where they're needed, with the belief that everyone deserves access to clean water. To add to the company's array of desalination solutions, Fluence's water experts have designed a family of pre-engineered building blocks that can be assembled into cost-effective seawater desalination systems that match any water sourcing need.

NIROFLEX Desalination

Developed from the highest quality standard components, NIROFLEX includes blocks for reverse osmosis, as well as pretreatment blocks for ultrafiltration and multimedia filtration. The versatility of the Niroflex system means the blocks can be arranged for capacities that produce from 100 m³/d (25,000 GPD) up to 15,000 m³/day (3.75 MGD) of clean water.

Reverse Osmosis
The reverse osmosis (RO) system is available with two high-pressure and energy-recovery technologies. Each can produce up to 2,000 m³/d (530,000 GPD) of permeate from a single RO skid. NIROFLEX’s RO is available in two technology options:

  • A positive displacement pump combined with an isobaric exchanger for low energy consumption and constant capacity in a wide range of temperatures
  • A centrifugal pump combined with a turbocharger, for lower CapEx investment
Niroflex pretreatment systems are available with two technologies:

  • Multimedia filter systems that produce up to 7,200 m³/d (1.9 MGD), with low CapEx investment, simple operation, and low chemical requirements
  • An ultrafiltration system that produces up to 6,200 m³/d (1.6 MGD), with high filtration ratings that correspond to long RO membrane lifecycles and a high rejection of total organic compounds (TOC)
Optional Features
NIROFLEX can be configured with a wide range of optional features, including:

  • Integrated cleaning in place (CIP) with an automatic flushing system
  • Compressor with air dryer
  • Feed pumping station
  • Alternative power supply
  • Remineralization
  • Delivery pumping station
  • Remote monitoring software with cloud-based data logging
  • High scalability

Featured Desalination Case Studies

NIROBOX™ SW Units for a Costa Rican Resort

Due to an ongoing drought, a beach resort with a 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, SWRO, and remineralization to drinking-water quality. The system was started up only several months after it was ordered, with a plan to gradually increase reliance on the system with the approach of the tourist season.

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 10 NIROBOX™ modular, containerized seawater desalination units to produce 10,000 m³/day of potable water. The 10 NIROBOX™ units were supplied in just four months.

NIROFLEX Desalination for Engineering Company

When an engineering company needed drinking water on Taiwan's Nangan and Dongyin islands, Fluence created a treatment train that included two 2,000 m³/d ultrafiltration units and two 600 m³/d reverse osmosis units, as well as energy-recovery devices. The manufacturing time was three months.
