Shield 1000 SystemOur initial goal is to supply 3.8 liters—about 1 gallon—per person, per day for several thousand survivors and responders. According to the Sphere Handbook's list of minimum standards in humanitarian response, between 2 and 3 liters are needed for drinking and cooking and another 2 to 6 liters for basic hygiene per person, per day.
The Roddenberry DRT plans to distribute at least 500 gallons (and perhaps in excess of 4,000 gallons) over a 12 hour span each day using two stage purification: ultrafiltration and UV plus the Puralytics' Shield System.That means delivering a gallon of water to a survivor every 90 seconds, or about 40 gallons per hour. However, the Shield takes 24 hours to process the 500 gallons at a rate of 21 gallons per hour. Water will be dispensed faster than it is generated, so a quiet period to recharge the tank overnight is required. In our Stage 2 purification, the Puralytics Shield uses a photocatalytic nanomembrane (very similar to a mycelial mesh) at its core. Water is pressed through the specially coated membrane and bombarded with high-intensity light from frequency-tuned LEDs to remove viruses, bacteria, protozoa, fuels, pesticides, fertilizers, and heavy metals such as mercury, arsenic, and lead from freshwater. The system is about 24 inches tall and weighs about 60 pounds. |
