Why Choose 8040HR Salt Water

🌊

99.8% Salt Rejection

The 8040HR maintains stable 99.8% rejection under real seawater conditions (32,000 mg/L TDS) — producing permeate that meets WHO drinking water guidelines in a single pass for most seawater sources.

🔬

Aquaporin Inside™ High-Rejection

Engineered specifically for high-salinity feeds. The biomimetic protein channels discriminate water from dissolved ions with exceptional precision — even at the extreme osmotic pressures of seawater desalination.

📐

Standard 8040 Format

Fits all standard 8" pressure vessels — drop-in replacement for conventional SWRO membranes in existing plants. No vessel modifications, no adapters, no re-plumbing.

💪

High-Pressure Rated

Tested at 800 psi with a design envelope that handles the demanding conditions of seawater service. Robust construction for continuous duty in marine and coastal environments.

How Customers Use 8040HR Salt Water

01

Seawater Desalination

Primary SWRO element for land-based and marine desalination plants. Single-pass permeate quality suitable for drinking water with minimal post-treatment.

02

High-Salinity Brackish Water

Inland brackish sources with TDS above 10,000 mg/L — where standard brackish membranes struggle with osmotic pressure. The 8040HR's high-pressure rating handles these challenging feeds.

03

Industrial Brine Treatment

Concentrate management, zero liquid discharge (ZLD) pre-concentration, and industrial process streams where conventional membranes cannot maintain rejection at elevated salinities.

8040HR Salt Water + The Heart

Desalinated water is aggressive and 'empty' — devoid of minerals and structure. Install The Heart post-RO to reintroduce natural water structure before distribution or consumption.
