No. STEAM-VOL1-NUM6-JUN2019; ISBN 978-0-9890870-3-2. ————— ABSTRACT: The histories of the Lenox Institute of Water Technology (LIWT), Krofta Engineering Corporation (KEC), their joint humanitarian engineering education and their step-by-step joint research leading to the development of various flotation drinking treatment processes, including the first drinking water flotation plant in Americas (Lenox Water Treatment Plant) and the once the largest drinking water flotation plant in the world (Pittsfield Water Treatment Plant) are presented. Also documented are their leaders, inventors, educators, co-designers, governmental officers, design concepts, flow diagrams, DAF-filtration (DAFF), plant performance, awards, DAF/DAFF future and related references. The flotation processes invented by LIWT, manufactured by KEC, and financed and collaborated by the above dedicated people are introduced: (a) dispersed air flotation; (b) electroflotation; (c) dissolved air flotation; (d) (e) two stage DAF-DAF clarifier system; (f) sedimentation-DAF clarifier; (g) DAF-filtration, or DAFF; (h) two stage DAF-DAFF clarifier system; (i) sequencing batch dissolved gas flotation; (j) sequencing batch induced gas flotation and (k) DAF-press thickener; (l) two-stage DAF-DAF water softening plant using magnesium carbonate as a recyclable coagulant, etc.
