This project will assess: 1) high water recovery and minimal brine discharge comparing recirculating and single-pass configurations, and 2) low electrical energy consumption through waste heat utilization and identification of energy efficient cooling approaches. Project implementation consists of three tasks: (1) Energy characterization - involves the investigation of energy properties of MD based on waste heat and cooling approaches and collection of time-varying temperature and flow rate data from waste-heat emitters; (2) Modification of bench-scale MD system and MD process intensification for recirculating feed configuration - involves modifications to the long-term bench-scale MD system in the laboratory and performing experiments to determine the optimal long-term operating conditions with a recirculating feed-stream configuration; and (3) MD process intensification for single-pass feed configuration - involves performing experiments to determine the optimal long-term operating conditions using a single-pass feed stream configuration. Results from the single-pass configuration will be compared to those from the recirculating feed configuration to determine the preferred feed-stream configuration.

The objective is to evaluate membrane distillation (MD) energy source, cooling alternatives, and feed configurations to enable higher water recovery, lower electrical energy consumption, and reduced brine discharge.
