    Abstract:
    Wang, LK, Wang, MHS and Fahey, E (2020). An innovative Lee, Massachusetts USA dissolved air flotation potable water filtration plant. In: "Evolutionary Progress in Science, Technology, Engineering, Arts, and Mathematics (STEAM)", Wang, Lawrence K. and Tsao, Hung-ping (editors). Volume 2, Number 1, January 2020; 60 pages. Lenox Institute Press, Newtonville, NY, 12128-0405, USA. No. STEAM-VOL2-NUM1-JAN2020; ISBN 978-0-9890870-3-2---------------The authors present the overall structural design, design criteria, and performance data of the two Krofta Sandfloat flotation-filtration clarifiers (DAFF; SAF-BP24) installed at the 2.0 MGD (7570 m3/day) Lee Plant in treatment of surface water for potable purposes. Lenox Institute of Water Technology (LIWT) invented and patented the innovative DAFF system, while Krofta Engineering Corporation (KEC) manufactured and installed the Lee Plant. The author also discuss (a) current corrosion control program in order to comply with the US Federal Copper and Lead Rule, and (b) the current DAF-filtration plant’s performance for removal of perchlorate, barium, sodium, disinfection by-products (DBP), total trihalomethane (THM), total haloacetic acid (HAA), microbial contaminants, turbidity, iron and manganese. The 19 years old innovative Lee DAF-filtration plant met all US Environmental Protection Agency, and the Commonwealth of Massachusetts primary and secondary drinking water standards in accordance with the 2018 Water Quality Report. The Town of Lee successfully uses zinc orthophosphate and pH adjustment to stabilize the water throughout of Lee distribution system for lead, copper and pipe corrosion control. This article has been written in memory of Dr. Milos Krofta, Dr. Donald B. Aulenbach and Dr. William A. Selke.
