| Summary: | Membrane Distillation (MD) system has been widely used for desalination for past decades to produce potable water for human cinsumption. However, current MD systems are fully dependent on electrical power supply for operation. In this work, a Parabolic Solar Thermal Collector (PSTC) integrated with Direct Contact Membrane Distillation (DCMD) system was designed to study the influence of a PSTC towards membrane performance. The objective of this w is to analyze the performance of the hybrid PSTC system with DCMD system in purifying seawater. PSTC was used as a support system to pre-heat seawater until the it reaches a certain temperature. In this project, as the temperature of seawater in the pre-heated tank reaches 45 °C, a 12 V submersible water pump will be automatically switched on and channel the seawater in the pre-heated tank into the feed tank of the DCMD system. In terms of energy consumption, less amount of energy is required to channel the seawater sample into the feed tank. In regards of system performance analysis, the hybrid system was compared to a DCMD system which utilises an electrical heater. It was noticed that only a marginal reduction in terms of permeate flux (7.1% difference) and salt rejection (0.8% difference) was observed when using the PSTC system. As a conclusion, the utilization of solar technology via a PSTC can potentially bring a lot of benefits in the desalination industry and in the future of employing MD system in the industry. |
