Columnar activated carbon treatment of food wastewater is truly low-cost and highly efficient.

The composition of food processing wastewater is particularly complex due to the wide range of raw materials in the food industry, including sugar, brewing, meat, milk, and other water discharged after food processing, which varies greatly in water quality. This type of wastewater primarily contains organic matter such as carbohydrates, proteins, and fats, as well as inorganic dyes and various suspended particles. These pollutants can lead to a rapid increase in dissolved organic matter in the water, causing it to deteriorate easily and develop a very pungent odor. Additionally, the wastewater is laden with a high concentration of bacteria and E. coli, often exceeding national discharge standards. It is imperative to treat the wastewater produced by the food industry to purify the water quality before it can be released.

The treatment of food processing wastewater is known as granular activated carbon, which primarily utilizes the micropores in the food processing process. By leveraging the adsorption properties of activated carbon, it吸附 a variety of impurities and pollutants generated during food processing, effectively purifying the water. The granular activated carbon filtration process is particularly simple, ensures stable water quality, and can significantly reduce the number of filtration steps, further saving on the cost of industrial wastewater treatment.
