An ultrafiltration water system keeps good minerals in your water without producing waste water. Ultrafiltration treatment runs at low water pressure, does not require a separate water holding tank does not alter the pH of your water, and does not require electricity. The Ultra filter membrane is stable at a wide range pH levels. Historically, ultrafiltration has been used in large municipal water treatment plants and hospitals; however thanks to technological advances you can now install a powerful under sink water filtration system in your home.
