Introduction: Most commercial surfactants used for cleaning (as detergents (are part of xezenbiotic compounds. These compounds and products due to its toxic effects on aquatic organisms may interfere with hormonal system and consequently change the echo system. Since the biodegradation of those compounds are weak, ordinary methods are unable to break down conventional purification. Therefore, t...
Background and Objective: Due to increasing the water demand and the lack of its resources, the reuse of effluents is considered as a useful option in the water resources management. The aim of this study was to evaluate the possibility of the reuse of effluents from the extended aeration process in the wastewater treatment plant of the Bojnoord city for agricultural uses. Materials and Method...
Electrochemical oxidation is a promising technology to treatment of bio-refractory wastewater. Coking wastewater contains high concentration of refractory and toxic compounds and the water quality usually cannot meet the discharge standards after conventional biological treatment processes. This paper initially investigated the electrochemical oxidation using boron-doped diamond (BDD) anode for...
aims: in biological wastewater treatment processes, a large amount of sludge is produced. stabilization of sludge is essential before disposal because of the risks to human health and environment. therefore, selecting an appropriate process for stabilization this sludge may efficiently decrease risks. the aim of this study was to examine the compound efficiency of the advanced fenton and ozonat...
In the present work advanced oxidation process, photo-Fenton (UV/H2O2/Fe) system, for the treatment of wastewater contaminated with oil was investigated. The reaction was influenced by the input concentration of hydrogen peroxide H2O2, the initial amount of the iron catalyst Fe, pH, temperature and the concentration of oil in the wastewater. The removal efficiency for the system UV/ H2O2/Fe at ...
