As a cost effective component in an ultrapure water system, the Shield 500 provides large reductions in TOC, solids, and pathogens in Type I, II, or III water:

The Shield 500 provides the broadest range of coverage for ground water contaminants, and is extremely effective for drinking water for residences and livestock. Some of the major sources of these contaminants are storage tanks, septic systems, hazardous waste sites, landfills, and the widespread use of fertilizers, pesticides and other chemicals. Most of the emerging contaminants on the EPA primary, secondary, or contaminant candidate lists are organics, pathogens, or metals that can be eliminated by the Puralytics Process.

In many locations in the world, either completely self contained water purification or complete isolation from the municipal supply is required. The self contained systems for the military must be able to purify water from any source to potable standards. The Shield 500 can provide a lower cost, more effective means to remove the most difficult contaminants. Because there are no chemicals required, the logistics of using the system are greatly simplified, and the rugged design, light weight, and simplicity of operation fit easily into this environment. Remote field offices cannot rely on the incoming municipal or well water quality for drinking or cooking. The Puralytics Shield in conjunction with an activated carbon filter can provide the required protection and safety.
