The datasheet also presents a table containing typical product flow rates, feed spacer thicknesses, a higher salt rejection (99.3%), membrane areas, and diameters for each model. Due to conflicting information regarding product flow rates between the general table and the explicit "Minimum Product Flow Rate" section, See the official PDF for exact tabulated values.

• TMH20A series elements are 8 inches in diameter and 40 inches (1,016 mm) in length.
• Other internal dimensions shown are 1.05 inches (26 mm) and 0.75 inches (19 mm).

Operating Information

• For the recommended design range, consult the latest technical bulletin, design guidelines, computer design program, or an application specialist.
• Failure to strictly follow the operating limits will void the Limited Warranty.
• Elements are wet tested, treated with a 1% by weight percent sodium bisulfite storage solution, and then vacuum packed in oxygen barrier bags.
• Alternatively, elements may be treated with tested feed water solution and vacuum packed with a deoxidant inside.
• To prevent biological growth during 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.
• The customer is fully responsible for the effects of chemicals that are incompatible with the elements; their use will void the element Limited Warranty.
