“…That is the reason why the search for improvements of the existing processes has led to the proposal of using zeolite as a microbial support and ammonium ion exchanger (Hedström 2001;Ho and Ho 2012;Mace and Mata-Alvarez 2002;Wei et al 2010;Wilderer et al 2000Wilderer et al , 2001.…”

One of the technologies used for wastewater nitrogen removal consists in simultaneous nitrificationdenitrification. The low microbial growth rate and the low availability of organic material for the denitrification stage make it necessary to study new operational conditions and the use of microbial supports. The aim of this study was to evaluate the operational behavior of a simultaneous nitrification-denitrification process in a sequential batch reactor utilizing zeolite as a biomass support and step-feed strategy. Two reactors of 2 L were used, one with zeolite and another without zeolite, both operated at constant temperature (31°C), varying nitrogen loading rate (NLR) from 0.041 to 0.113 kg total Kjeldahl nitrogen (TKN/m 3 /day). After 209 days, removals higher than 86 and 96 % in nitrogen compounds and organic matter were obtained, respectively. There was not accumulation of nitrate and nitrite in any case; this means that there was a simultaneous nitrification-denitrification in the reactors. The incorporation of zeolite in the system held higher concentration of biomass in the reactor; this led to reduce start-up to 21 days and to improve 11.31 % removal kinetic. The use of a stepfeed strategy prevents events of inhibition by substrate, even duplicating tolerance to higher NLR for the same operation time.

“…As a high efficiency and inexpensive method to treat wastewaters, SBR technology has been widely used through the years (Mace et al, 2002). It has been also successfully emplored to treat pollutants of various types of wastewaters (Lamine et al, 2007;Giordano et al, 2005;Obaja et al, 2003;Jin et al, 2015).…”

Abstract. The objective of this study was to investigate the pollutant removal efficiency of different types of wastewaters by a sequencing batch reactor (SBR). A laboratory-scale SBR was used to treat sewage, medical wastewater and industrial wastewater. The effects of different conditions of aeration, stirring and settling on the efficiency of pollutants removal were explored to optimize the performance, especially for the removal of organic matter (COD), ammonia nitrogen (NH 4 + -N), total nitrogen(TN) and total phosphorus(TP) of different types of polluted water. From the results it was showed that when aeration 6 hours, stirring 4 hours and settling 2 hours in SBR, the removal rates of COD, nitrogen and phosphorus of domestic sewage were 93%, 98% and 83%, respectively; when aeration 5 hours, stirring 5 hours and settling 1 hour in the SBR, the removal rates of COD and nitrogen of pharmaceutical wastewater were 83% and 90%, respectively; when aeration 4 hours, stirring 4 hours and settling 1 hour in the SBR, removal rates of COD, nitrogen and phosphorus of industrial wastewater were 97%, 93% and 97%, respectively.

“…COD and BOD 5 removal rates were 85% and 95%, respectively. 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).…”

“…LASs are utilized in household detergents like washing powder, dishwashing detergent, etc. (17,18). In aquatic environment, detergents float on the surface of water as a surface layer and disfigure the aquatic environment, reduce gas exchange and endanger the aquatic animals' health by decreasing the dissolved oxygen.…”

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.
