Note on other specifications: The provided text includes a fragmented table containing values for product flow rate, feed spacer thickness, salt rejection, and membrane area for various models (TM720C-440, TM720C-400, TM720C-430). Due to fragmentation and potential inconsistencies, please see the official PDF for exact tabulated values for these parameters.

Storage and Handling

Elements are wet tested and treated with either a 1% by weight sodium bisulfite storage solution or tested feed water solution, then vacuum packed in oxygen barrier bags (with deoxidant inside for the latter). For short-term storage, shipment, or system shutdown, it is recommended that elements be immersed in a protective solution containing 500 - 1,000 ppm of food-grade sodium bisulfite dissolved in permeate. Permeate from the first hour of operation shall be discarded.
