Advanced water treatment technologies as well as improved design are being developed all over the world to keep up with industries' demand for treated water. AWTS does more than keep up with these technologies. We train your plant crews in the latest operations techniques and procedures. We also have developed break-through innovations of our own.

AWTS Design and Technologies special expertise include:

  • Media, multi-media, mixed-media filtration
  • Micro filtration and Ultra Filtration
  • Reverse osmosis membrane filtration
  • EDI systems
  • Forced draft, vacuum, and membrane degasifiers
  • Ion-exchange, (IX) demineralization
  • ZLD systems, and ultraviolet disinfection
  • UV and sterilizers for disinfection and TOC destruction

AWTS propritary technologies.

Stainless Steel Resin TrapTrap internals

  • RESIN TRAPS: Developed exclusively by AWTS to save owners expense on wasted media and resin and to prevent cross contamination of critical process components downstream. See features.
  • HIGH EFFICIENCY FILTER NOZZLE (PATENT APPLIED FOR): This nozzle provides outstanding performance over the traditional internal nozzles for filters and demineralizer applications. Installed capacity over 5,000 gpm. See story.
  • INTERNAL DISTRIBUTORS: Several type of internal distributors for media filters, ion exchange demineralizers and vacuum degasifiers. Design options include wedge wire screens, slotted distributors, pipe base laterals, header-lateral design, hub-spoke design, header-lateral design with drop strainers, etc. Stainless steel, Hastalloy-C, Monel, Sch. 80 PVC, PPL, PVDF and other materials. Retrofitted several systems having problems with product water quality, chemical regeneration efficiency, channeling, etc. Routinely work with several screen manufacturers.
  • PRESSURE VESSELS AND LINING: ASME Code, Section VIII, Division-1 for carbon steel vessels, ASME Code, Section X for FRP vessels, black rubber lining, white rubber lining. Familiar with PVDF, PPL, and Halar lining procedures. Routinely work with several pressure vessel and lining manufacturers.
