DuPont (Dow) RO Membrane Elements

Name: DuPont (Dow) RO Membrane Elements
Brand: Xinnian
SKU: LCLE4040 / BW30-400 / BW30FR-400/34

LCLE4040 / BW30-400 / BW30FR-400/34

DuPont (Dow) FilmTec RO and nanofiltration elements use a spiral-wound composite structure with even flow distribution, fouling tolerance and easy cleaning, and are widely used for brackish water desalination and industrial pure water. Common models include LCLE4040, BW30-400, BW30-400IG, BW30FR-400/34 and BW30FR-400/34i, where the FR range is the fouling-resistant version.

Key Features

FilmTec composite membrane with stable rejection and flow
BW30FR fouling-resistant range for high-COD and scaling-prone water
Standard 4-inch and 8-inch elements with wide interchangeability
Array design and operating parameter calculations available
