Aquavus, water purifying

It is no secret that a shortage of clean drinking water is a major issue all over the world.

According to the World Health Organization, unsafe drinking water was responsible for nearly half a million deaths in India in 2010.

Paul Rewrie is one of the leaders of a British company that developed Aquavus, a new technology that uses ultrasound to purify and desalinate seawater and clean contaminated water.

One unit can purify 3,000 liters (about 800 gal) a day. The average water use per day per person in France is 280 liters.

The scale of water usage in a village in the developing world, however, is much different. Each villager uses about 20 liters of water a day for drinking, cooking and bathing. A single Aquavus unit could supply enough clean water to support the needs of 150 people per day.

"The Aquavus system uses powerful ultrasound to blast impure water into particles of less than 10 µ. These micro-particles evaporate and condense to form pure water," Rewrie said.

Aquavus is still in the developmental stages. "Our alpha prototype machine proved that our technology works in lab conditions," Rewrie said. "Now we need to build three beta prototypes, and the projected cost is $300,000. We will then build the final industrial machines, which will lead to the licensing across the world."

In order to generate this capital, Rewrie and his team have launched an Indiegogo campaign.

Donations of any amount are welcome. Those who contribute $50 will receive an Aquavus baseball cap. For $75, contributors will get an "I Love Drinking Water" T-shirt.

"Our goal is to keep the final products at prices below $1,000 for the seawater unit and $500 for the artesian and surface water units," Rewrie said.

One of the members of the Aquavus team is Dr. Ravi Kumar, who wrote and directed "Bhopal: A Prayer For Rain," a film starring Martin Sheen, Kal Penn and Mischa Barton. The movie is inspired by the 1984 Union Carbide disaster.
