Low-temperature distillation plants: a comparison with seawater reverse osmosis
Low-temperature distillation plants using large aluminum-alloy heat-transfer surfaces have reduced energy requirements to levels projected today for second-generation seawater reverse-osmosis (SWRO) plants. Less sensitive to feed contamination, and totally free from maintenance associated with a complex and critical feed-pretreatment system and periodic membrane replacements, the low-temperature distillation plants out-perform SWRO plants also by their higher-quality product, 2-10 ppM TDS versus 300 to 1000 ppM TDS. Energy requirements and operating costs for Low Temperature Vapor Compression (LT-VC) and Multi-Effect-Distillation (LT-MED) plants, in dual-purpose and various waste-heat-utilization schemes, are compared with those of SWRO plants. 10 references, 14 figures, 8 tables.
