Water Filtration Solutions For Process Water

Utility water is used in a wide variety of ways depending on the type of process. From chemicals to petrochemical plants, process water is a widely used commodity. However, depending on the source of the incoming water-municipal water plant, well water or surface water - a number of filtration steps may be required to produce water that is acceptable for use in the application. For example, incoming water may contain particulate and bacteria that can foul RO membranes, damage pump seals, clog nozzles, contaminate catalysts, etc., leading to costly repairs or downtime. Proper water treatment is often a complex multi-stage process. Depending on the contaminant load in the incoming stream it may be prudent to first treat with a coarse sand or multimedia followed by an activated carbon bed to remove dissolved organics. Treatment may also involve the use of deionizing resins (to remove dissolved inorganic salts), reverse osmosis membranes (to reduce salts and dissolved organic material), special adsorbents (to remove heavy metals, arsenic and lead), and ultraviolet light (to kill bacteria and other microbial contaminants). Graver offers a number of products that can be used as part of a comprehensive water treatment process.

About Our Filtration Products For Process Water

  • Pre-RO filters to protect the RO membranes from fouling
  • Tank vent filters prevent ingress of airborne mold and bacteria
  • Trap filters downstream of sand, resin, and carbon beds
  • Pre-filters to prevent particulate loading of carbon and ion exchange resin beds
  • Absorbents to remove arsenic III which is not removed by the RO membrane

Product Selection

  • CMBF™ or MBC™ Melt blown depth filters for Pre RO filtration to prevent membrane fouling.  1 or 5 micron is most typically used.
  • Stratum® Melt blown depth filter, PMC™ or PMA™ cartridge Series are ideal for removing particulate down stream of carbon, sand and resin beds as trap filters.
  • WaterTEC™ PES or ZTEC™ G membrane when sub-micron purity levels are required
  • TefTEC™ V Hydrophobic PTFE membrane for tank vent applications
  • High Flow™ large geometry filters to meet large volume flow demands
  • MetSorb® HMRG Highly specialized adsorbent material removes heavy metals, lead, and arsenic from water.  MetSorb even removes the arsenic III, which is not readily removed by RO membranes (RO effective at arsenic V removal).
