🛡️ Feed Spacers (34-mil Diamond Feed Spacers, Biological Fouling Resistance)

LPRO Spiral-Wound Element Feed Spacer Calculator

Model open-channel diamond and parallel feed spacer geometries ($28 ext{ to }34 ext{ mil}$ thickness) inside spiral wound RO/NF membrane envelopes: minimize dead-zone flow stagnation, prevent biofouling particulate entrapment, reduce feed-to-reject delta pressure ($Delta P < 1.0 ext{ bar}$ per vessel), and membrane uptime yields.
