Design Specifications

The patented Puralytics® process employs LEDs to excite a nanotechnology mesh which purifies water following five-step light-activated purification processes. The five-step process includes:

• Photocatalytic Oxidation – eliminates organic compounds
• Photocatalytic Reduction – reduces compounds & heavy metals to a less toxic state
• Photoadsorption – irreversibly adsorbs heavy metals; mercury, lead, chromium, arsenic, etc.
• Photolysis – high energy breaks up chemical compounds to enhance the other processes
• Photodisinfection – high-intensity multiple wavelengths more effective than UV irradiation

• Water recovery: 100%
• Water production: 0.5-2.6 L/min (200–1000 gallons per day)
• Pressure drop: 5–25 psi @ 200-1000 gpd
• Power consumption: 570 Watts
• Power input: 100-240 V; 50 Hz-60 Hz
• Dimensions: 81.3 x 30.5 x 45.7 cm
• Weight: 27.2 kg
• Ambient operating temp: 5°C–30°C (41°F–86°F)
