Dimensions (TM720 series)

  • Outer Diameter: 7.9 inches (201 mm)
  • Length: 40 inches (1,016 mm)
  • Permeate tube inner diameter: 1.125 inches (29 mm)

Operating Information

  • All elements are wet tested.
  • Elements are treated with a 1% by weight sodium bisulfite storage solution and then vacuum packed in oxygen barrier bags, or treated with tested feed water solution and vacuum packed with deoxidant.
  • 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 sodium bisulfite (food grade) dissolved in permeate.
  • Permeate from the first hour of operation shall be discarded.
