Among the food industries, the dairy industry is considered to be the most polluting one because of the large volume of wastewater generated and its high organic load. In this study, an aerobic membrane bioreactor (MBR) was used for the treatment of wastewater from a large dairy industry and two hydraulic retention times (HRT), 6 and 8 hours, were evaluated. For both HRTs removal efficiencies o...

background : in this study, the inhibitory effect of ethylene dichloride (edc) on biodegradation was investigated using the specific methanogenic activity (sma) test of anaerobic biomass. methods: in the present study, 40 sma tests were performed using 120-ml vials in batch mode. substrate, biomass, and biogas occupied 66%, 17%, and 17% (v/v) of the volume of each vial, respectively. the durati...

This chapter provides a general overview of physical–chemical wastewater remediation systems in the food industry. Water reuse systems are becoming more and more interesting and promising technologies, depending on merely quantitative estimations, physical and chemical features of pollutants and the variability of these characteristics, week after week. Different systems are available for the f...

The use of chlorine bleaching in study and pulp industry has resulted in chlorinated phenol contaminated wastewater from that industry. A new wastewater treatment process, sonophotodegradation of 2,4,6-trichlorophenol (TCP) in a heterogeneous aqueous system was investigated and reported in this study. TCP was degraded with ultrasonic or ultraviolet irradiation or a combination of both, in the p...

A simple technology for phosphate (P i ) recovery has been developed using a bifunctional adsorption-aggregation agent. The bifunctional agent was prepared by soaking calcium silicates in hydrochloric acid solution. Importantly, recyclable calcium silicates were available almost free of charge from the cement industry and also from the steel industry. The acid treatment was essential not only f...
