FilmTec is the global volume leader; Toray is the dominant brand in Asia and the Middle East. Both manufacture seawater, brackish, and tap water RO membranes with similar performance envelopes. Toray's TM820 series is widely deployed in Saudi, UAE, and Israel for proven fouling tolerance in high-organic waters. Toray has slightly better boron rejection (~1-2 percentage points) which matters for irrigation applications and certain industrial processes. FilmTec has slightly broader product range covering specialty brackish and nano-filtration. In standard SWRO duty, the choice typically comes down to availability and existing-plant compatibility. Yes, Toray TM820 series matches FilmTec SW30 within 1-2 percentage points on every key spec. Both are accepted by major engineering firms for SWRO design. Possible but not recommended within a single pressure vessel. Operating parameters tune slightly differently. Better to standardize on one brand per train.
