Description
The Dow Filmtec LE-440i element is a low energy featuring breakthrough membrane chemistry. The HRLE-440i element delivers the same 99.5% nominal NaCl rejection as traditional brackish water elements but at 33% lower pressures.
– Lower energy requirement allow new reverse osmosis system 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 rejections (IPA rejections is a common surrogate for TOC removal)– Available dry for longer storage life and easier handling
