This paper argues that a fit-for-purpose model and datasets are necessary to generate transition pathways for the electricity generation sector at the subnational level. We present the methodology, data, and results focusing at a sub-national level, the state of West Bengal in India. The approach can be generalized for any region with necessary cus...

In the case of abattoir effluent, biological nutrient removal in sequential batch reactor (SBR) is achieved typically through pre-denitrification, which can be accomplished during the anoxic fill phase or an anoxic react phase between the fill and the aerobic react phase. The study includes phosphorus reduction from abattoir wastewater in a SBR und...

A laboratory-scale study was conducted in a 20.0-L sequencing batch reactor (SBR) to explore the feasibility of simultaneous removal of organic carbon and nitrogen from abattoir wastewater. The reactor was operated under three different combinations of aerobic-anoxic sequence, viz., (4+4), (5+3), and (5+4) h of total react period, with influent sol...

Wastewater containing high concentration of oxygen-demanding carbonaceous organics and nitrogenous materials (chemical oxygen demand (COD) and total Kjeldahl nitrogen (TKN)) as nutrients emanated from small- to large-scale slaughterhouse units cause depletion of dissolved oxygen in water bodies and attributes to the threat of eutrophication. Biolog...

The present paper deals with treatment of slaughterhouse wastewater by conducting a laboratory scale sequencing batch reactor (SBR) with different input characterized samples, and the experimental results are explored for the formulation of feedforward backpropagation artificial neural network (ANN) to predict combined removal efficiency of chemica...

The performance of a laboratory-scale sequencing batch reactor (SBR) of 20-litre capacity was evaluated for simultaneous removal of soluble COD (SCOD), NH<sub align="right"> 4 </sub><sup align="right"> + </sup>–N and phosphorus by changing the compositions and concentrations of substrates under different combinations of REACT period. The total cycl...

The performance of a laboratory-scale Sequencing Batch Reactor (SBR) has been studied in aerobic-anoxic sequence for simultaneous organic carbon and nitrogen removal. The reactor was operated under three different variations of aerobic-anoxic sequence, viz. 4+4, 5+3 and 3+5 hours with input solutions of soluble COD (SCOD) level 1000 +/- 100 mg/L an...
