This Technology Spotlight highlights solids separation approaches that deliver high performance in compact footprints and challenging hydraulics. Submissions are encouraged that present technology description, field data and operational experience. Technologies may include but not limited to flotation techniques such as dissolved air flotation (DAF), suspended air flotation (SAF), and also high-rate clarification including ballasted flocculation clarification, and lamella/inclined plate clarification. Topics of interest include retrofits and intensification, performance under flow/load swings, chemical conditioning and floc management, solids handling and thickening outcomes, and lessons learned from startup through steady-state operation.
