GK series
Engineering summary from PDF text extraction for GK series. Verify every value with the OEM datasheet.
Summary
Product identification
The GK Series consists of industrial ultrafiltration (UF) elements, featuring a thin-film membrane (TFM) with a molecular weight cutoff (MWCO) of 3,500 Daltons. These proprietary G-Series elements are characterized by a smooth, fouling-resistant membrane surface.
GK Elements are designed for applications such as surface water pretreatment, color/total organic carbon (TOC) reduction, and chemical purification.
