Water purifier can cut back on pollution, save millions of dollars: Aquasentry
The Aquasentinel Water Purifier, a small portable water purification device, can reduce water usage and save millions in pollution by replacing household wastewater, according to a study published online by Stanford University.
The device, which cost about $300, is being developed at Stanford and is being marketed to local governments and environmental groups in San Francisco, Santa Clara County and the San Francisco Bay Area.
The Aquasenteel Water Purification System uses a small, portable water filtration device that filters out wastewater from the soil to a tank containing water that’s then pumped to a filter that separates water from the contaminants.
The system, which was built at the University of California, Berkeley, and is available for sale at home, is currently in the early stages of testing.
According to the Stanford study, the Aquasenterel Water purifiers water is 50 to 75 percent cleaner than a standard household filter, which is about 1.4 times cleaner than conventional water purifiers.
The researchers found that the Aquosentinel system has the potential to reduce wastewater-pollution levels in an area by about 10 percent compared to conventional water systems.
“It’s really great that people can have access to affordable water purifying devices that are environmentally friendly, and the results are really good,” said Dr. James H. Shackelford, professor of environmental engineering and director of the Water and Waste Institute at Stanford.
Water purifiers are commonly used to help cities and other large urban areas deal with high levels of water pollution.
Water purifying water systems are also often used in schools and other community centers to help people avoid potentially dangerous bacteria and pollutants in the water supply.
There’s been an increased emphasis on clean water for decades, particularly in China, where more than 70 percent of water is considered polluted.
In China, the country’s largest urban area, there are about 12 million people, or about one in three people, that are in need of drinking water, according a 2012 report by the World Health Organization.
Researchers say the Aquinasentinel could help reduce water pollution by reducing waste from the process.
While the Aquisentinel purifies water, the device also converts it into drinking water.
The conversion process takes about 10 minutes and takes about 30 seconds per 1,000 liters of water, which means the Aquensentinel can reduce the water footprint by about 20 percent compared with standard water systems, the study found.
This is a great product that can help reduce the environmental impact of our water,” said Shackelford.
Another environmental benefit of the Aquasesentinel is that the water purifies much faster than a conventional water system, said Shacckelfords study co-author Andrew J. R. Pappas, a professor of public policy at Stanford who worked on the project with Stanford’s Department of Energy.
Pappas and Shackeefords study looked at a variety of different scenarios involving different water systems in San Mateo County, where the Aquasisentinel was tested.
Rising demand for drinking water has been a major concern for the county.
San Mateo is one of the largest cities in the country, and about 1,800 people work in San Jose, Calif.
There are about 4,500 homes in the San Mateos area.
The water use of those homes is estimated at more than 8,000 gallons per person per day.
About half of that water comes from a combination of private and public sources.
To meet the water needs of those residents, the city has spent more than $1 billion on water infrastructure in the past decade.
San Matey’s water infrastructure is estimated to be at least 20 percent below its target level of 5 million gallons per day by 2040.
More than two-thirds of the water used in San Diego County is used to irrigate farms and farms are also the source of the majority of water for the city.
Even if the Aquaresentinel does not significantly reduce the amount of water that goes into the San Diego region’s drinking water system from agriculture, the technology could be a significant boon for the region, said Pappass.
Because of the nature of wastewater, Pappasses said the Aquosesentinel would likely be used in areas that are highly polluted.
He also noted that the device is only about three inches long, which could help protect against spills from water that is being treated in the Aquaseentinel.
