DWP System
A chemical-free solution to reduce Legionella risk in domestic water systems
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:
- Eliminate incoming bacteria, nutrients and Legionella
- 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
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
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
DWP System Enhances Other Treatments
- With Chlorine Dioxide, Liquid Chlorine and Monochloramine, disinfection byproducts and piping corrosion are the biggest problems. Since DWP minimizes bacteria entering the system and helps remove the biofilm and scale where the existing bacteria is colonized, a much lower chemical dosing is needed which significantly reduces disinfection by-products and corrosion.
- With Copper-Silver Ionization, the primary problem is scaling on the cathode which hinders or stops the treatment and requires maintenance. DWP System will eliminate the scaling and should also allow a smaller copper-silver dosage and thus longer life of the copper-silver rods.
A variety of internal and external factors can lead to Legionella problems in your building, including:
