Abstract A flocculation and air floating process for extracting yeast protein directly from weakly acidic organic waste liquid includes heating the fermented yeast liquid whose pH value is 3-6 to 35-45 deg.C, adding poly iron aluminium chloride (0.003-0.025%) and sodium polyacrylate (0.01-0.08%), stirring with jet pump which sucking air, dripdrying for 1-2 hr, delivering the flocculated yeast protein to belt-type vacuum filter to obtain cakes, drying and breaking. Its advantages are lower energy consumption, high yield and quality of product, and low COD of discharged water.
