MEMBRANE

Features :

DOW FILMTEC™ 4.6-inch diameter RO elements offer high quality water for sanitary applications, using the high performance TW30HP membrane, which offers excellent permeate flow and sait rejection. These elements are made with the same high quality materials of construction as our larger DOW FILMTEC elements used in municipal and industrial systems. For added convenience during shipping, storage and loading, these elements are available as either wet or dry products.

  • pH Range, Continuous Operation"  2- 11
  • pH Range, Short-Term Cleaningb    1 - 13
  • Maximum Feed Silt Density Index   5
  • Free Chlorine Tolerancec                 < 0.1 ppm

Maximum tempe,ature for continuous operation above pH 10 is 95° F (35°C)

Refer to cleaning guidelines in specification sheet 609-2301 O.

Linder certain conditions, the presence of free chlorine and other oxidizing agents Will cause premature membrane failure. Since oxidation damage is not covered under warranty, DW&PS recommends removing residual free chlorine by pretreatment prior to membrane exposure.
