Aquaporin Inside® · Biomimetic RO Membrane
CLEAR Plus 8040-440
Buy Aquaporin CLEAR Plus 8040-440 — a low-energy biomimetic RO membrane 8040 with Aquaporin Inside® aquaporin protein technology, NSF 61 certified, 440 GPD nominal flow, and ≥ 99.7% salt rejection. Following Aquaporin A/S bankruptcy, Waterheart holds remaining Aquaporin membrane stockpile in Europe — in-stock 8040 reverse osmosis membrane elements for municipal, industrial, and wastewater reuse.
Specifications
Module Data
Test conditions: 2,000 mg/L NaCl, 15.5 bar (225 psi), 25 °C, pH 7, 15% recovery. Flow rates are nominal; actual performance depends on system design and feed water quality.
Why CLEAR Plus
Aquaporin Inside® Advantage
Lower Operating Pressure
Biomimetic aquaporin proteins allow water to pass through the membrane at lower transmembrane pressure — reducing energy consumption by up to 20–30% versus conventional TFC membranes.
High Permeate Quality
Stabilised salt rejection of ≥ 99.7% ensures consistently high-purity permeate suitable for drinking water, process water, and reuse applications.
High Water Recovery
Designed for 2-stage system configurations achieving up to 80% system recovery, minimising brine discharge and maximising the value of source water.
NSF 61 Certified
Certified to NSF/ANSI/CAN 61 — fully approved for drinking water contact applications, meeting the highest material safety standards.
Drop-In Compatible
Fits any standard 8-inch inner diameter pressure vessel. Direct replacement for conventional 8040 elements — no system modifications required.
Long-Term Stability
Proven reliable performance over extended operation with minimal flux decline, even in challenging municipal and industrial feed waters.
Applications
Where It's Used
Municipal Drinking Water
Treatment of well water, groundwater, and surface water with elevated TDS, hardness, fluoride, or nitrate. Documented case results show 20–30% energy savings versus conventional membranes at the same flow and rejection targets.
Industrial Process Water
High-purity water production for food & beverage, pharmaceutical, electronics, and chemical manufacturing — as well as humidification, ice-making, steam generation, and spot-free washing.
Municipal Wastewater Reuse
Treatment of secondary or tertiary municipal effluent for indirect potable reuse, industrial reuse, or agricultural irrigation. Suited to 2-stage RO configurations at 80% system recovery.
Brackish Water Desalination
Treatment of inland brackish water (TDS 1,000–10,000 mg/L) for potable or process water supply in water-scarce regions and remote locations.
Installation
How to Install an 8040 Element
The CLEAR Plus 8040-440 fits any standard 8-inch inner diameter pressure vessel and installs identically to conventional 8040 RO elements.
- 1 Prepare the pressure vessel — Clean the interior wall. Remove end caps and any existing elements. Inspect O-ring grooves for damage.
- 2 Lubricate O-rings — Apply only food-grade glycerine to the U-cup brine seal and interconnector O-rings. Never use petroleum-based lubricants.
- 3 Load the element — Insert from the brine (reject) end, pushing forward until the element protrudes 20–30 cm from the vessel opening, then push fully home.
- 4 Connect elements in series — Link multiple elements (typically 6–7 per vessel) using the permeate tube interconnectors so feed flows axially through the spiral-wound path.
- 5 Install end caps and piping — Secure end caps and connect feed inlet, brine outlet, and permeate outlet to your system piping.
- 6 Flush and commission — Flush at low pressure (≤ 4 bar) to remove preservatives, then gradually ramp to operating pressure (typically 10–15 bar for brackish water).
