Abstract

A new distributed boosted multi-effect distillation (DBMED) process was developed for low-grade heat source in the temperature range 65 °C- 90 °C. NPV and IRR indexes were used to analyse the economic viability of DBMED. A novel zero-liquid discharge(ZLD) process entitled Cascaded Fluidised Bed (CaFB) Ice Slurry Generator was proposed for salinity range beyond70,000 ppm, in order to reduce the volume of brine. The issue of scale formation in industrial evaporation process was also studied using a JWP Alfa Laval freshwater generator, modified to be a test rig for spent Bayer liquor for a 14-day continuous trial.
