Description Technical Specifications


Featuring breakthrough membrane chemistry, the DOW™ FILMTEC™ HRLE-440i element delivers the same 99.5% nominal NaCl rejection as traditional brackish water elements but at 33% lower pressures.

• Lower energy requirements allow new reverse osmosis systems to be designed to use one third less energy and still deliver the same permeate quality compared with other BW elements

• Existing low energy systems can be retrofitted to achieve lower permeate TDS than possible with previous low energy elements

• The combination of low energy and high rejection is ideally suited for use in the second pass of seawater and high-purity applications

• Excellent rejection of silica, boron, nitrate and ammonium; supported by Dow’s modeling software

• Increased IPA rejection (IPA rejection is a common surrogate for TOC removal)

• Available dry for longer storage life and easier handling
