NFS Sulfate Removal Membrane, Approx. Molecular Weight Cutoff 100-250Da, Synder Filtration (CAT#: STEM-GMAE-3050-LGZ)

The scale formed after the precipitation of barium sulfate and strontium sulfate plays an important role in limiting oil recovery. In addition, sulfate is a major source of sulfur during the formation of hydrogen sulfide, resulting in well acidification. Therefore, several water treatment steps are required to minimize sulfate concentration prior to injection. Due to the high repellency of divalent ions such as sulfate, nanofiltration is well suited to mitigate sulfate ion-induced scaling and acidification. Synder filtered NFSTM membranes allow greater flux and rejection efficiency than ever before. Synder Filtration is pleased to introduce NFSTM, a nanofiltration membrane specially formulated to provide superior sulfate filtration in applications such as water injection in the oil and gas industry.
