Notes:
A two-stage tubular hyperfiltration (reverse osmosis) pilot plant equipped with 15.6 m2 of aromatic polyamide thin film composite membrance (ZF 99) was studied with tomato juice (4–6% natural tomato soluble solids [NTSS]). It was operated over 100 hr in recirculation and single pass modes. The single pass mode was operated at33–38 bar (feed inlet pressure) and 70–93°C for 18.2 hr. Stage 1 flux was 48 to 34 Lm−2hr−1. Stage 2 flux was 30 to 20 Lm−2hr−1. Concentration went to 7.4–9.0% NTSS at 8.6 L/min, and to 6.3–6.4% NTSS at 18.6 L/min. NTSS rejection was 〉98%. Of permeate samples tested none showed detectable levels of sugars; only 25% showed detectable levels of organic acids.
