Hydrolysed corn or other starch is clarified by a process which comprises forming in the syrup at a pH of 3.5 to 6.5 a primary floc formed between aluminium ions, hydroxide ions, and phosphate ions; aerating the syrup containing the primary floc; distributing an anionic organic polymeric flocculant through the aerated syrup to initiate the formation of a secondary floc; allowing the secondary floc to grow, and to segregate by flotation; and separating flocculated solids from clarified syrup. |
