H2FLOW EQUIPMENT INC. supplied an ISAM SBR system designed to provide the performance required. The system features an integral sludge digestion tank, an equalization tank and a true sequencing batch reactor section. As the discharge is to environmentally sensitive underground wells, the ISAM was chosen as the high performance ...
Sequencing batch reactor (SBR) was assessed for direct co-treatment of old landfill leachate and municipal wastewater for chemical oxygen demand (COD), nutrients and turbidity removal. ...
A decentralized full-scale sequencing batch reactor (SBR) system for treating wastewater was operated to assess their feasibility and the response of bacterial population dynamic and nutrient removal performance. ...
The main difference in the operation of both reactors was the dissolved oxygen (DO) concentration in the bulk liquid. SBR-1 was started at a DO value of 0.4 mg O2/L whereas SBR-2 was started at DO values of 3.0 mg O2/L. ...
AGS can be developed in a sequencing batch reactor (SBR) with alternating anaerobic–aerobic conditions. To provide anaerobic conditions, the mixed liquor is allowed to circulate in the reactor without air supply. ...
Pharmaceutical wastewater generated by an antibiotics (penicillin) company was treated by aerobic membrane bioreactors (MBRs) and sequencing batch reactors (SBRs). At a low organic loading rate of 0.22 kg-COD m−3d−1, both types of reactors were capable of treating the wastewater such that the treated effluent met the discharge regulation except for the total ...
This study deals with the ozonation of amoxicillin in real pharmaceutical wastewater and its efficacy as a pre-treatment, prior to biological degradation by a mixed culture of bacteria in a sequencing batch reactor (SBR). An ozone utilization of 0.27 g/g-COD (chemical oxygen demand) lowered the pH of the wastewater to 6.6, reduced the specific ultraviolet absorption by ...
Is your Sequencing Batch Reactor (SBR) or other activated sludge process in need of a cost effective upgrade or expansion due to it being outdated, overloaded, inefficient or undersized? ...
The application procedure for this product was very simple: Microcat - DEN is a dry powder and was added to one of the two SBRs at the dosage below: Days 1 and 2: 3 kilos (6.6 lbs) per day Days 3 through 20: 2 kilos (4.4 lbs) per day Days 21+: 0.5 kilos (1.1 lbs) per day maintenance This unique parallel application program design offers the opportunity to isolate the ...
In this work the autotrophic nitrogen removal was carried out at moderately low temperatures using two configurations: a) two-units one comprising a SHARON reactor coupled to an Anammox SBR and b) single-unit one consisting of a granular SBR performing the CANON process. ...
This study investigated the effects of repeated starvation and feeding on the performance of a sequencing batch reactor (SBR) used for treating saline wastewater. The effects of aerobic and non-aerobic conditions on the sludge during starvation were evaluated to recover the performance of the SBR in terms of floc size and ...
Since cometabolism was proved to enhance 4CP biological removal, a conventional Sequencing Batch Reactor (SBR) was used in this study for the cometabolic aerobic degradation of 4CP at different influent concentrations and volumetric organic loading rates (40–50 mg/L and 0.129–0.323 kgCOD-4CP/m3·d, respectively), with sodium acetate (NaAc) as the growth substrate. The effects of ...
The methodology is evaluated on a pilot-scale SBR performing nitrogen, phosphorus and COD removal and to help to diagnose abnormal situations in the process operation. ...
In this study, two Brocadia-like anammox phylotypes were successfully enriched, detected and identified from an activated sludge taken from a domestic wastewater treatment plant (Minas Gerais, Brazil) employing a Sequencing Batch Reactor (SBR). The dominant phylotype was closely related to ‘Candidatus Brocadia sinica’, but one clone seemed to represent a novel species for which ...
We investigated the operation of two laboratory sequencing batch reactors (SBR) under low phosphate conditions over a period of eight months. Performance characteristics in terms of COD and TSS removal were similar to the full-scale mill activated sludge operation, but the floc density and structure was improved. ...
In this study, the combination of magnesium ammonium phosphate (MAP) precipitation and Sequencing batch reactor (SBR) was suggested as a new process for the treatment of high strength ammonium, and the effect of high concentration of Cl− after MAP precipitation because of the use of MgCl2 was investigated on SBR performance. The practical upper ...
This study investigated the effect of organic carbon source on ammonia oxidizing community in single sludge laboratory scale sequencing batch reactors (SBR). Two sequencing batch reactors performing simultaneous carbon oxidation and nitrification were operated. ...
Waste Management evaluated some solutions and finally opted for the Ecoprocess SBR solution by Premier Tech Aqua (PTA) in answer to the following: High performance Ecoprocess SBR can meet the new leachate ammonia concentration standards Green technology Ecoprocess SBRs are designed to preserve sensitive areas such as the ...
Challenges The municipality of Cardinal investigated possible treatment solutions offering the following: High performance A technology that can handle typical diluted municipal sewage with BOD5 of 80 mg/L during dry flow conditions and ensure less than 1 mg/L phosphorus concentration at all times Flexibility A technology that can show stable performance in ...
