High Area Utilization Stack. Part 1. Design and Develop Stack Components, Build and Test a Short Stack

摘要

The capability of scaling up membrane desalination modules is an important design characteristic when multi-million gallons per day desalting plants are being considered. One of the primary objectives of the project was to extend module scale-up to the maximum extent practicable to effect potential savings in capital cost. A 54 x 40 inch slanted strap pattern (SSP) spacer was designed from analyses of hydraulic resistance, open area, and membrane support characteristics. The design was scaled back to 9 x 10 inch and 18 x 40 spacer sizes to evaluate the pattern design and potential fabrication methods. The project concluded with the fabrication and preliminary testing of a short 54 x 40 inch SSP stack with 20 cell pairs.
