Shear-enhanced flotation separation to treat winery wastewater

Wineries generate variable wastewater effluent that could be costly to treat and difficult to discharge or reuse. A shear‑enhanced flotation separation (SEFS) process – combining hydrodynamic shear, coagulation, flocculation and dissolved air flotation was designed, developed and piloted to address this challenge using winery wastewater.
