Computational modeling and evaluation of reverse osmosis and forward osmosis water treatment technologies integrated with CCHP waste heat
- Seawater reverse osmosis (RO), Forward Osmosis (FO) and the FO/RO hybrid process have received increased attention. Providing waste heat of a CCHP plant to these membrane technologies could benefit both energy efficiency and environmental impacts of the hypothetical integrated infrastructure system. In order to evaluate the potential benefits, simulation and modeling need to be performed taking all possible system parameters into consideration. In this study, a simulation approach for RO and FO water treatment processes is presented. The design space of a preheated RO system is explored, using the amount of water produced per unit cost as the optimization objective. The results show that typical optimal designs have 70~90°C operating temperature, 0.3~0.5 recovery goal, 50~60 bar operating pressure and larger design capacity.
