Evaluation of sequencing batch reactor performance for petrochemical wastewater treatment
Sequencing batch reactor (SBR) technology has found many applications in industrial wastewater treatment in recent years. The aim of this study was to determine the optimal time for a cycle of the sequencing batch reactor (SBR) and evaluate the performance of a SBR for petrochemical wastewater treatment in that cycle time. The reactor was operated with a suspended biomass configuration under ae...
متن کاملSequencing batch biofilter granular reactor for textile wastewater treatment.
Textile wastewater is difficult to treat as it usually contains considerable amounts of different pollutants, which are often recalcitrant, toxic and inhibitory. Therefore, complex treatment schemes based on the sequence of various steps are usually required for an effective treatment. This explains why textile effluents are often treated in centralized plants and sometimes mixed with municipal...
متن کاملinvestigation of operating parameters on wastewater treatment using sequencing batch reactor
due to the population growth and human activities in the agricultural and industrial fields, healthy and sanitary water has become scarce. due to its high contamination load, environmental harms and water discharge standards, starch producing industry is regarded as one of the industries polluting water sources which its treatment and recovery remains important. in the present study, after fabr...
متن کاملPerformance and microbial ecology of a nitritation sequencing batch reactor treating high-strength ammonia wastewater
The partial nitrification (PN) performance and the microbial community variations were evaluated in a sequencing batch reactor (SBR) for 172 days, with the stepwise elevation of ammonium concentration. Free ammonia (FA) and low dissolved oxygen inhibition of nitrite-oxidized bacteria (NOB) were used to achieve nitritation in the SBR. During the 172 days operation, the nitrogen loading rate of t...
متن کاملSequencing Batch Reactor: a Promising Technology in Wastewater Treatment
Discharge of domestic and industrial wastewater to surface or groundwater is very dangerous to the environment. Therefore treatment of any kind of wastewater to produce effluent with good quality is necessary. In this regard choosing an effective treatment system is important. Sequencing batch reactor is a modification of activated sludge process which has been successfully used to treat munici...
