| Researchers at Purdue University have developed a new approach to water treatment known as batch reverse osmosis (RO). Reverse osmosis is a critical step to water treatment to meet the need of clean drinking water for a growing global population. The technique created by Purdue researchers features a high-pressured feed tank with a reciprocation piston that fills one side with the following cycle's feedwater and then alternates treated water for new water repeatedly until at least 50% recovery is achieved, keeping permeate separate from either semi-batch. This approach shortens the traditional flushing step of emptying the feed tank as well as prevents brackish water and brine from mixing with the new feed, which is a major concern with standard systems. The batch RO method has potential to operate below 2 kWh/m^3 power for seawater and takes just 10% of the downtime of the entire RO process. Advantages -Reliable -Lessens Downtime Between Batches -Reduces Entropy Generation -Low Power Potential Applications -Reverse Osmosis -Water Treatment |
