The potential of ultrasonic membrane anaerobic systems in treating slaughterhouse wastewater
Direct discharge of slaughterhouse wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand. In this study, an ultrasonic-assisted membrane anaerobic system was used as a novel method for treating slaughterhouse wastewater. Six steady states were achieved, using concentrations of 7,800–13,620 ...

Reusing date seed residues as a low cost adsorbent for slaughterhouse wastewater purification
Date seeds were found to be as effective adsorbents as activated carbon for the removal of organics from slaughterhouse wastewater. Experiments were successfully employed to attain the maximum amount of COD adsorption. The maximum adsorption capacity were 53 and 60 mg/g for date seeds and activated carbon, respectively. In view of the stringent water quality requirements, adsorption using date ...

Anodic oxidation of slaughterhouse wastewater on boron-doped diamond: process variables effect
A non-sacrificial boron-doped diamond electrode was prepared in the laboratory and used as a novel anode for electrochemical oxidation of poultry slaughterhouse wastewater. This wastewater poses environmental threats as it is characterized by a high content of recalcitrant organics. The influence of several process variables, applied current density, initial pH, supporting electrolyte nature, ...

Factors affecting phosphorus exports from sites irrigated with abattoir wastewater
Abattoir wastewaters often contain significant quantities of phosphorus, inorganic salts, nitrogen and biodegradable organic materials. The nutrients in abattoir wastewaters are potentially useful for plant production and in many countries the application of abattoir wastewaters to land is considered a preferable option to other forms of treatment. In this paper we investigate the factors that ...
