One market APTWater is focused on is capturing and treating waste water leaving landfills. The leachate produced by landfills poses a major problem to landfill operators and the environment alike.
Leachate occurs when rainfall and other moisture hits landfills. Mixed with contaminants, the liquid becomes toxic. If left sitting in the bottom of the landfill, leachate eventually leaches into the groundwater, making it unsafe.
Rochem, an APTwater company, is a developer of membrane systems. Their reverse osmosis technology is specifically designed to handle the leachate produced by landfills. The technology is installed at Orchard Hill Sanitary Landfill in Watervleit, Michigan.
Here’s how their technology works:
Raw leachate passes through a reverse osmosis membrane, removing 99% of contaminants. That clean water then passes through a second membrane to remove a further 99% of contaminants. The resulting water so clean, it needs to be re-mineralized before being returned to the environment.
Advantages of the Rochem reverse osmosis system include: automation, which frees up operator time; lower operating costs; zero by-products; a smaller footprint than other comparable systems; and the use of clean energy technologies that lower the overall environmental impact. www.aptwater.com
