DWP System

A chemical-free solution to reduce Legionella risk without additional domestic water system corrosion

EasyWater’s DWP (Domestic Water Protection) System is a unique, three-part solution for domestic water filtration and treatment. The DWP System utilizes EasyWater’s SedimentShield—a sub-micron, backwashing filter with proprietary media for the removal of sediment and bacteria; an ultraviolet chamber for bacterial sanitization; and EasyWater’s No Salt Conditioners to reduce or eliminate hard water scale deposits and biofilm in the domestic water system.

DWP System Features & Benefits

The 2 Key Factors for Protecting Domestic Water Systems from Legionella Problems:

  1. Eliminate incoming bacteria, nutrients and Legionella
  1. Remove existing biofilm and scale deposits so it has no place to live and multiply

DWP System Components:

SedimentShield Sub-Micron Filtration

  • Utilizes EasyWater’s sub-micron SedimentShield media, which is a proprietary blend of media that backwashes clean and does not harbor bacteria
  • SedimentShield media has an expected life of 15+ years
  • Removes over 99% of sediment, unwanted nutrients, and bacteria from the water, which significantly reduces the threat of Legionella in domestic water systems
  • Reduces turbidity or cloudiness in the water, which increases the effectiveness of the UV system

UltraViolet (UV) System

  • Kills bacteria on contact
  • UV provides highly effective sanitization and is protected from deposits and performance loss by the SedimentShield filtration and No-Salt Conditioner

No-Salt Conditioners

  • Minimizes Legionella risk throughout the domestic water system by eliminating scale buildup and reducing or eliminating system biofilm
  • Reduces or eliminates existing biofilm in both hot and cold domestic water systems
  • Helps maintain the rated effectiveness of the UV by preventing scale and biofilm on the UV lamps
  • Prevents and removes scale buildup in the domestic water system, helping water-using equipment last longer and work more efficiently

A variety of internal and external factors can lead to Legionella problems in your building, including:

 Biofilm     Scale and Sediment     Changes in municipal water quality
