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 indlucing volatile organic chemicals, radon, chlorine
•          and some heavy metals

  Mechanically remove 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) Membranes for Drinking Water Purification

 Flters 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 electropositive 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) monodisperse latex spheres or 25 nanometer virus, giving it an Absolute rating of .03 microns.

 Effective over pH 5-10, water temperatures 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 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 is not completely clear is not effectively sanitized by UV

 Affects waterborne contaminants and disease causing pathogens at a 99 % kill rate

 Bulbs must be changed every year to ensure maximum efficiency

 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
