a thermophilic anaerobic contact reactor for the treatment of potato-processing wastewaterswas designed as a continuous-flow, completely-mixed homogeneous system. the reactor was operated at ten different organic loading rates ranging from 0.84 g cod/l·d to 7.00 g cod/l·d for a duration of approximately 250 days. the fundamental way to maintain optimum operating conditions of anaerobic digestio...

In order to achieve satisfactory biological treatment of wastewater, the wastewater should contain sufficient carbon, nitrogen, phosphorus, and trace minerals to meet the metabolic requirements for cell growth. For most food processing wastes, nutritional balance is not a problem since there usually is enough carbon, nitrogen, phosphorus, and trace minerals. However, certain food processing was...
Introduction: Effluents of Meat processing are one of the untreated wastewaters containing high volumes of polluted components even after the primary and secondary treatments. The high cost of using the advanced treatment methods of the wastewaters has led the industry owners to release them in the nature without effective removal of nitrogen and phosphorus. In this study, an economic advanced ...
Microbial fuel cells (MFCs) are emerging as promising technology for the treatment of wastewaters. The potential energy conversion efficiencies are examined. The rates of energy recovery (W/m3 reactor) are reviewed and evaluated. Some recent data relating to potato-processing wastewaters and a hospital wastewater effluent are reported. Finally, a set of process configurations in which MFCs coul...
Over ten million tonnes of solid residues are generated yearly from coffee agro-industry worldwide, along with larger amounts of wastewaters and cultivation residues. Both wastewaters and solid residues, such as defective coffee beans and spent coffee grounds, along with coffee husks (pulp and mucilage) that constitute around 60% of the wet weight of the fresh fruit, represent a relevant source...
Dairy factory wastewaters are increasingly being considered a valuable resource. However, these waters may also contain contaminants, natural or artificial, that may adversely affect the land to which they are applied. This review investigates dairy wastewaters, factors affecting their composition, some probable effects on land and compounds that may be used to trace the migration of pollutants...
