Reverse Osmosis Membrane Elements

The contract involves the procurement of 1,680 new reverse osmosis (RO) membrane elements to replace aging components at the Silicon Valley Advanced Water Purification Center. The membranes must be standard 8-inch by 40-inch thin-film composite spiral-wound units, primarily from LG Chem NanoH₂O, Model BW 400 ES, or other pre-qualified manufacturers that meet Valley Water's specifications.

Delivery will be staged in lots of 560 elements per RO train, aligned with Valley Water’s installation schedule, and a manufacturer’s representative must be present during installation to oversee handling, loading, and startup procedures. The solicitation, issued by the Santa Clara Valley Water District in California, was posted on August 27, 2025, with a response deadline of September 24, 2025.
