“…Other studies investigated the use of the SBR method in treating different types of industrial wastewaters; however, their results indicated lower removal efficiency of COD compared to the present study (4,20,23,24). Therefore, the SBR system performs better in treating municipal wastewaters that contain organic matters with higher biodegradability compared to industrial wastewaters.…”

“…The SBR system can be used in biological treatment of different types of industrial and municipal wastewaters (17). Different studies have been conducted on treatment of biological wastewater of olive oil industry (18), wastewaters containing antibiotics (19), removal of cyanide from wastewater of electroplating industry (20), textile industry wastewater (21), wastewaters containing phenol (22), coal industry wastewaters (23), wastewaters with high concentrations of nitrogen (12), and domestic wastewaters and waste leachate (24).…”

Background: Linear alkyl benzene sulfonates (LAS) are the most important ionic detergents that produce negative ions in the environment. These compounds enter surface waters through domestic and industrial wastewaters and cause environmental hazards. Objectives: The present study was aimed at assessing the performance of advanced sequencing batch reactor (SBR) in wastewater treatment plant of Yazd, Iran, to remove organic materials and detergents. Materials and Methods:The present research was a descriptive longitudinal study conducted on 96 input and output samples of SBR system over eight months from October 2012 to June 2013. The studied parameters were biochemical oxygen demand 5 (BOD 5 ), chemical oxygen demand (COD), and detergents (LAS), which were assessed through standard methods. Finally, the study data were analyzed through analysis of variance (ANOVA) using software package for statistical analysis (SPSS). Results: The mean inputs of BOD 5 , COD, and LAS to the SBR system were 292.40 ± 45.28, 597.15 ± 97.30, and 3.29 ± 0.92 mg/L, and the mean outputs were 20.59 ± 3.54, 59.34 ± 9.47, and 0.606 ± 0.09 mg/L, respectively. The removal efficiency of BOD 5 , COD and LAS were respectively 92.95%, 90.06% and 81.6%. The results of ANOVA indicated that there was a significant relationship between the mean inputs and outputs of BOD 5 , COD, and the detergents (P ≤ 0.001). Conclusions:With the proper operation of wastewater the treatment plant and increasing the retention time, the removal efficiency of the detergents increased. In addition, according to the environmental standards for BOD 5 , COD and the detergents, the results of the present study indicated that the outputs of these parameters from the SBR system were appropriate for agricultural irrigation.

“…Dash et al [2] have recently reviewed and compared methods that have been investigated for the removal of cyanide from wastewater. Although biodegradation is usually the preferred technique for treating wastewater due to its cost-effectiveness and environmental friendliness, there is little information on the use of bioprocesses for treatment of cyanide-laden wastewater (e.g., [6][7][8]). Cyanide is toxic to microorganisms, particularly in high concentrations [1], which leads to a low biodegradation rate and restricts the potential of bioprocesses for efficiently removing cyanide and its compounds.…”

A B S T R A C TBackground and objectives: phenol, cyanide, and chromium (VI) are toxic pollutants. They can be discharged from different industries simultaneously such as iron and steel industry, coal mining, automobile manufacturing of parts. Presence of these pollutants in water and wastewater is a serious hazard and these substances lead to undesirable effects on both the environment and human. Thus, control of these contaminants is essential for human health and environment. The main objective of this study was to assess the efficiency of Fenton process for simultaneous removal of phenol, cyanide, and chromium (VI) from synthetic wastewater. Materials and methods: This study is an experimental study in lab scale that was carried out in a batch system. Variations of this study including pH, chemicals concentration (Fe 2+ and H 2 O 2 and molar ratio Fe 2+ /H 2 O 2 ), and reaction time were investigated. Cyanide, phenol, and total chromium were determined respectively by colorimetric method (spectrophotometer), highperformance liquid chromatography, and atomic absorption spectrophotometer. Results: The results of this research showed that simultaneous removal efficiency of phenol, cyanide, and chromium (VI) from synthetic wastewater by Fenton process were 88, 86 and 92%, respectively (conditions: pH = 4, Cr 6+ and CN À = 10 mg l À1 , Phenol = 150 mg l À1 , H 2 O 2 = 150 mg l À1 , Fe 2 + = 140 mg l À1 (Fe 2+ /H 2 O 2 = 0.58) after 30 min reaction time). Conclusion: According to the results, it can be concluded that Fenton process can be considered as a suitable process for cyanide, phenol, and chromium (VI) removal to achieve environmental standards.
