Treatment and Recycling of Wastewater from Food Industry using Fixed-Bed Adsorption Treatment on the Tertiary Stage

Abstract

Water pollution occurs when toxic pollutants of varying kinds (organic and inorganic) are directly or indirectly discharged into water bodies without adequate treatment to remove such potential pollutants. Today's sources of these potential pollutants, which cause high deterioration of freshwater quality, are industrial waste discharge, and industrial waste disposal practices. Therefore, the development of wastewater treatment processes to alleviate water pollution has been challenging and demanding. Food wastewater was characterized using COD, DO, Turbidity, pH, TS, TDS, and TSS. Comprising a mixture of areas including physical, and chemical methods to remove various potential pollutants. In this study, coagulation, sedimentation, and adsorption treatment were used to remove the pollutants contained in wastewater and also the treated water recycled back to the food processing industry. In addition, Superpro Designer Software was used to design a water recycling system that successfully meets the requirements of the standard A Regulation on Malaysia Environmental Quality.
