📝 Description
This used Applied Membranes Model S-128D is a dual-skid seawater reverse osmosis (SWRO) system offering 25.5 GPM continuous permeate capacity or up to 35 m³/day in 6-hour run mode. Designed for plug-and-play deployment, it features high-temperature-tolerant membranes, a 40 HP stainless steel feed pump, and programmable industrial microprocessor controls (I-ROC S150).
With 12 high-temp 8” × 40” membrane elements, this RO unit is ideal for challenging feedwater environments, operating at 340–540 psi (23–37 bar) and up to 10,000 ppm TDS. Features include CIP (clean-in-place) capability, auto-permeate flush, and an antiscalant injection system.
