Padre Dam Municipal Water District is considering two technologies to achieve a high recovery with reverse osmosis for its upcoming advanced water purification facility. Pilot testing from 2016-2017 at Padre Dam?s demonstration facility has shown that 95% recovery is possible with either a closed circuit desalination process and a conventional 2-st...

The objective of this study is to lower the energy and chemical use for the Full Advanced Train, required in California for potable reuse. The study offers an innovative approach to mitigate biological and organic fouling of membrane systems and enhance process water quality leading to reduced operating and maintenance (O&M) costs. This is accompli...

The current study summarizes findings of over 9-month long optimization study evaluating different chemical dosing strategies to address common scalants, such as calcium phosphate, on reverse osmosis membrane systems used in municipal wastewater treatment for potable reuse. The type of project testing different dose strategies in this case at demon...
