What is food industry wastewater?<\/span><\/h2>\n
    \n
  • \n
    Food waste is a liquid waste stream arising from food processing, pretreatment and preservation activities at food production facilities such as aquatic processing plants, cattle slaughterhouses, meat processing plants, collective kitchens, restaurants, hotels…<\/span><\/div>\n<\/li>\n
  • \n
    The composition of food wastewater is diverse, including biodegradable organic substances such as proteins, fats, inorganic substances such as mineral salts, pathogenic microorganisms, cleaning and disinfection chemicals…<\/span><\/div>\n<\/li>\n
  • \n
    Food wastewater flow depends on the scale, operating capacity of each facility. Can range from several tens to several hundred cubic meters per day.<\/span><\/div>\n<\/li>\n<\/ul>\n
