Question:
Afton inventor designs a self-contained home sewage treatment system any stories about Home Reverse Osmosis?

Answer: Every time Clint and Bobbi Elston flush a toilet or turn on their tap, they make history. Elston's gray water-treatment system involves three huge cone-shaped water tanks. Inside two of them are hundreds of little open plastic balls where bacteria live and eat the gunk that comes through the water. The water then goes through an extensive filtering process involving ozone, micron filters, ultraviolet light and reverse osmosis before it is stored in another tank.

A computer system continually tests the water and alerts the Elstons to any problems. They can also monitor the system on the Internet, he said.

The finished product is purer than bottled water, Bobbi Elston said. "You don't have to worry about 3M chemicals," she said, referring to recent groundwater-contamination problems in south Washington County. "We're using what the Lord has given us, and it's much better quality water."

She keeps two plastic Ziploc bags of ice cubes in the freezer. The clear ones are made from recycled gray water; the cloudy ones come from well water, she said. "There's a huge difference in quality," she said.
