The theories, principles, specific engineering design, potential applications, and practical applications of circular gravity flotation process, a floated fiber detector, and some new inventions are introduced in Evolutionary Progress in Science, Technology, Engineering, Arts, and Mathematics (STEAM)  are in memory of Dr. Milos Krofta, who was the founder and the President of both the Lenox Institute of Water Technology (LIWT) and Krofta Engineering Corporation (KEC). Although specific LIWT/KEC process equipment are mentioned as typical examples or case histories, the authors are introducing the circular gravity flotation process, the circular gravity sedimentation process (using zero horizontal velocity concept), enclosed biological flotation, and the fiber detector in general terms to be a progress report in STEAM (science, technologies, engineering, arts, and mathematics) for benefiting both academic and engineering communities. Any researchers and equipment manufacturers are encouraged to follow the authors’ foot-steps, and develop or build their own similar process equipment, for similar applications.
