Abstract
A process for removing proteinaceous materials, fats and oils from food processing wastewater using a coagulant such as lignin or a halogen ion containing compound together with a flocculant such as a natural polymer such as a polysaccharide or synthetic polymer is described. The combination of lignin or halogen and polymer is effective for coagulating and flocculating proteinaceous materials, fats and oils in food processing wastewater at low pH.
