Drinking Water Filtration Technology

Every water treatment technology has individual strengths in removing contaminants. In all applications a combination of technologies is optimal in reaching each customer's pure water goal. 

With over twenty years of experience specializing in water purification, you can depend on American Water Systems' professionals to design a water filtration system that will fit your organization's specific needs. 
Sediment Filters for Drinking Water Purification

  • Typically used as pre-treatment water filters for other technologies
  • Effective at removing suspended materials, such as sand, silt, loose scale, clay or organic matter
  • Water filter removes insoluble iron and manganese
Granular Activated Carbon (GAC) & Carbon Block Water Filters
  • Absorptive/Reactive water filter
  • Removes organic compounds including volatile organic chemicals, radon, chlorine and some heavy metals
  • Mechanically removes particles down to 0.5 micron, including Giardia and Cryptospordium, turbity and particulates
  • Not generally effective at removing dissolved inorganic contaminants such as minerals/salts
Reverse Osmosis (RO) Membanes for Drinking Water Purification
  • Filters water through a synthetic membrane trapping impurities - impurities are transported to a drain and purified water is sent to storage tank
  • Removes nearly all dissolved solids or minerals and radiologicals
  • Highly effective in removing dissolved salts - great for desalination applications and areas with high concentration of nitrates/heavy metals
  • Creates a waste stream of impure water
NanoCeramic Filtration for Drinking Water Purification

The NanoCeramic Filter is a highly electro-positive water filter that rapidly absorbs particles, no matter how small. The media has a high capacity for particles as large as tens of microns or as small as a few nanometers. A single layer of media retains greater than 99% of 30 nanometers. (.30 microns) mono-disperse latex spheres or 25 nanometer virus, giving it an absolute rating of .03 microns.
  • Effective over pH 5-10, water temperature of 4-50 degrees C and in the presence of dissolved salts
  • Separates particles by charge rather than by size
  • Higher retentivity for virus than "Absolute" ultra porous membrane water filters
  • Endotoxin in removal > 99.96%
  • DNA removal >99.5%
  • Pleated versions have 5-8 times higher dirt holding capacity than typical cartridges
  • Water filtration efficiency for micron size particles > 99.995%
  • High particle removal efficiency
  • No waste streams
UltraViolet Light Sterilization for Drinking Water Purification
  • Water that's not completely clear is not effectively sanitized by U V
  • Affects waterborne contaminants and disease causing pathogens at a 99% kill rate
  • Bulbs must be changed every year to ensure maximum effiiciency
  • Inserted as the last piece of a water filtration system
Ozone Sterilization for Drinking Water Purification
  • Most effective sterilizing method available today
  • Generates a supply of ozone (O3) electronically
  • Employs a significant residual effect
  • Very useful for treating water stored in tanks, such as cooler reservoirs
  • Highly effective in destroying pathogens, when its work is completed pathogens break down into oxygen
  • Added dissolved oxygen enhances water's taste
