Spiral Water Filtration
PARC, a Xerox company
Blue is the new Green. In much of the developing world, water filtration is limited due to both high cost and large space requirements. But, PARC has devised a more affordable, energy-efficient alternative to traditional, membrane-based treatment systems. PARC’s spiral concentrator pumps water through a 50-cm-long strip of plastic tubing that filters out offending particles by centrifugal force. The particles cling to the walls of the tubing, while more than 90 percent of the water emerges, fit for a variety of uses. PARC scientists and engineers are scaling the system to enable commercial implementation and designing each model to filter up to 100 liters per minute.
