Synder Introduces New NFS™ Membrane for Sulfate Removal Applications

Synder Filtration is pleased to introduce NFS™, a nanofiltration membrane, specially formulated to deliver superior sulfate rejection in fast growing applications such as water flood injection processes in the oil and gas industry. In seawater, sulfate ions interact with barium and strontium, resulting in scale formation that significantly reduces process output and efficiency. Nanofiltration is a proven separation technology in sulfate removal, and with the NFSTM membrane, a 30% increase in efficiency and potential reduction in NF system footprint is possible.

NFSTM provides a consistent, average sulfate rejection of 99.5% and surpasses the leading competitor in terms of both sulfate rejection and permeate flux in ASTM synthetic seawater tests (see Fig. 1). Consistent with characteristics of other Synder Filrtation nanofiltration membranes, NFSTM exhibits stable flux, consistent rejection, and high mechanical strength and integrity as well as excellent pH, temperature, and fouling resistance.
