TORAY TM820C-400 (High Rejection Seawater RO Membrane)
📝 Product Description
The TORAY TM820C-400 is an industrial-grade Seawater Reverse Osmosis (SWRO) membrane element, designed for treating high-salinity water sources (typically >10,000 ppm TDS) with a focus on high-quality permeate. This 8-inch diameter by 40-inch long element utilizes a cross-linked fully aromatic polyamide composite membrane to achieve an impressive stabilized salt rejection of 99.75%.
