Datasheet summary
GK series
PDF datasheet mirror for GK series (SUEZ Ultrafiltration). Verify with OEM before design.
Summary
Product Identification
The SUEZ G-Series family of proprietary thin-film ultrafiltration (UF) membrane elements, specifically the GK series, features a molecular weight cutoff (MWCO) of 3,500 Dalton on polyethylene glycol and a smooth, fouling-resistant membrane surface.
GK Elements are designed for applications such as surface water pretreatment, color/TOC reduction, and chemical purification.
Membrane Type: G-Series, Thin-Film Membrane (TFM*) Molecular Weight Cutoff (MWCO): 3,500 Dalton
