Wastewaters generated from food production and agricultural activities are a source of environmental pollution due to their huge amount of nutrients, organic carbon, nitrogenous organics, inorganics, suspended and dissolved solids, and high biochemical and chemical oxygen demands. Advanced Technologies in Wastewater Treatment: Food Processing Industry provides an update on emerging technologies including oxidative and anaerobic processes (flotation, coagulation, sedimentation, filtration, adsorption, primary settling, secondary activated sludge, anaerobic digestion), ion exchange, membrane-based operations, adsorption/bio-sorption and advanced biological treatment to provide safe and clean water as well as to recover primary resources from food processing wastewaters. In addition, the integration of these technologies will be also considered in the logic of the process intensification strategy. Innovative and affordable solutions are proposed in the field of fruit and vegetable processing industry, fishing industry, meat and poultry industry, dairy production, oil and fat processing.
