Energy efficiency of batch and semi-batch (CCRO) reverse osmosis desalination.
As reverse osmosis (RO) desalination capacity increases worldwide, the need to reduce its specific energy consumption becomes more urgent. In addition to the incremental changes attainable with improved components such as membranes and pumps, more significant reduction of energy consumption can be achieved through time-varying RO processes including semi-batch processes such as closed-circuit r...
متن کاملAn on-line batch span minimization and quality control strategy for batch and semi-batch processes
A novel strategy is proposed to minimize the operation time of batch and semi-batch processes. The proposed on-line strategy is based on linear regression models and employs a cascade control structure in which the primary controller calculates an optimal operation profile for the secondary controller to follow. A special feature of the proposed on-line strategy is that it conducts runwise info...
متن کاملEnergy and Resources Recovery from Reverse Osmosis Desalination Concentrate
The overarching goal of this research project is to develop technologies for beneficial salinity management. Specifically, the project focuses on the energy and resources recovery from reverse osmosis (RO) desalination concentration, which can reduce the cost associated with desalination operation and minimize the environmental impact associated with the disposal of desalination concentrate. Th...
متن کاملBatch and Semi-batch Process Efficiency Comparision
In this paper recent semi-batch chromium sludge processing is compared with batch processing by simulation means mainly. A possible time and/or power consumption reduction using these two techniques is monitored to optimize the process. The process itself is strongly exothermic so the temperature control is necessary to keep the temperature under critical temperature point.
متن کاملNovel Membrane Materials for Reverse Osmosis Desalination
The use of solvents in desalination processes limits the use of certain materials in the construction of the reverse osmosis membranes. Therefore now the research effort has focused on improving new materials. In particular, nanostructured materials will probably form the basis for new reverse osmosis membrane materials. This study makes a review of the new materials used for the construction o...
