Company Introduction

Membrane Elements and Engineered Systems from One Partner

Our mission is to provide high-quality membrane technology that supports sustainable water management and reliable purification worldwide.

Our product portfolio spans the full spectrum of RO membrane technology, from ultra-low pressure elements for drinking water production to high-pressure seawater desalination membranes, fouling-resistant membranes for challenging feedwater, and high-pressure nanofiltration elements for zero liquid discharge processes. Alongside membrane elements, we supply complete RO systems and application-specific desalination equipment, enabling customers to source both core membrane components and engineered solutions from a single partner.

All membrane elements are manufactured under strict process controls, with stable membrane chemistry and consistent dimensional tolerance, ensuring reliable drop-in compatibility with standard pressure vessel configurations and industry-recognized element specifications.

Blue Membrane products are widely applied in desalination, ultrapure water production, industrial process water, wastewater reuse, food and beverage processing, and commercial purification systems. We work closely with system integrators, OEM partners, and distributors to deliver stable membrane performance and dependable supply.

Core Competencies

What Blue Membrane Brings to Your Project

Broad Product Coverage

Blue Membrane offers seven distinct membrane series — covering low-pressure RO, brackish water RO, fouling-resistant RO, seawater RO, nanofiltration, high-pressure ZLD nanofiltration, and residential/custom elements — as well as complete RO system skids and application-specific water makers and desalination units.

FilmTec-Compatible Elements

Key series within the Blue Membrane product line are engineered as direct performance equivalents to widely specified DuPont FilmTec reference models, facilitating straightforward evaluation and replacement in existing systems.

Custom Element Manufacturing

Through our BE series, we support OEM and ODM customers with fully customizable membrane elements across a broad range of diameters (35–90 mm), lengths (180–333 mm), and flux ratings (50–1,600 GPD), with dimensional tolerances held to ±0.5 mm. Customization extends to end cap design, seal configuration, and private-label branding.

System Integration Capability

Beyond membrane elements, Blue Membrane designs and supplies skid-mounted and containerized RO systems for seawater and brackish water applications, as well as marine water makers, portable desalination units, and RO fresh water generators for vessel and offshore use.

Global Service Reach

Blue Membrane products are deployed in water treatment projects across more than 20 countries, spanning industrial water reuse, island and coastal desalination, commercial water purification, and marine applications. We work with system integrators, OEM manufacturers, and regional distributors to support product selection, technical evaluation, and ongoing supply.

Precision Manufacturing & Quality Control

With a commitment to precision manufacturing, stable membrane chemistry, and strict quality control, Blue Membrane delivers reliable products that meet the demanding requirements of modern water treatment systems. Our membranes are engineered to provide high rejection, excellent permeability, and long operational lifetime while maintaining strong resistance to fouling and chemical stress.
