CSM RE8040-BLN 12000 GPD BW-LE Commercial Membrane

CSM RE8040-BLN 12000 GPD BW-LE Commercial Membrane

Item SKU: RE8040-BLN

MFG ID: RE8040-BLN | UPC:




The CSM RE8040-BLN 12000 GPD BW-LE Commercial Membrane combines quality and functionality with durability for a lifetime of customer satisfaction. With its long filter life, it makes a valuable addition to the water filter system. It removes impurities from water to making it safe to drink.

Features:

  • Elements contained in the boxes must be kept dry at room temperature (7-32°C; 40-95°F) and should not be stored in direct sunlight. If the polyethylene bag is damaged, a new preservative solution (sodium bisulfite) must be added and air-tight sealed to prevent drying and biological growth
  • Permeate from the first hour of operation should be discarded to flush out the preservative solution
  • Elements should be immersed in a preservative solution during storage, shipping and system shutdowns to prevent biological growth and freezing. The standard storage solution contains 1% by weight sodium bisulfite or sodium metabisulfite (food grade). For short term storage (i.e. one week or less) 1% by weight sodium metabisulfite solution is adequate for preventing biological growth
  • Keep elements moist at all times after initial wetting
  • Avoid excessive pressure and flow spikes
  • Only use chemicals compatible with the membrane elements and components. Use of such chemicals
  • void the element limited warranty
  • Permeate pressure must always be equal or less than feed/concentrate pressure. Damage caused by permeate back pressure voids the element limited warranty

Design Guidelines for Various Water Sources:

  • Wastewater Conventional (SDI < 5): 8-12 gfd
  • Wastewater Pretreated by UF/MF (SDI < 3): 10-14 gfd
  • Seawater, Open Intake (SDI < 5): 7-10 gfd
  • Seawater, Beach Well (SDI < 3): 8-12 gfd
  • Surface Water (SDI < 5): 12-16 gfd
  • Surface Water (SDI < 3): 13-17 gfd
  • Well water (SDI < 3): 13-17 gfd
  • RO permeate (SDI < 1): 21-30 gfd

Saturation Limits (Using Antiscalants)†:

  • Langlier Saturation Index (LSI): <+1.5
  • Stiff and Davis Saturation Index (SDSI): <+0.5
  • CaSO4: 230% saturation
  • SrSO4: 800% saturation
  • BaSO4: 6,000% saturation
  • SiO2: 100% saturation
    †The above saturation limits are typically accepted by proprietary antiscalant manufacturers. It is the user’s responsibility to ensure proper chemical(s) and concentration are dosed ahead of the membrane system to prevent scale formation anywhere within the membrane system. Membrane elements fouled or damaged due to scale formation are not covered by the limited warranty.
