Introduction:The waste water treatment plant at Oldcastle will built to serve the agglomeration ofOldcastle municipal co-operation Meath with the design capacity of 1500 population. Theconstruction of a new wastewater treatment plant to serve the population of the Oldcastlecommenced in upcoming year. The construction of this new plant will be completed inupcoming next year. The following calculation have been prepare as per requirement ofwastewater plant. The process and to obtain design parameters are discuss in report segment.Aim:To design an activated sludge plant for Oldcastle residencies from the total amount ofpopulation done wastewater flow.Objective:Design municipal activated sludge wastewater treatment plant for Oldcastle city through thepreliminary laboratory bacterial growth and utilising wastewater at that area.To determine the substrate utilisation and growth rates for sludge from the exponentialgrowth phase of growth.Plot data to estimate maximum specific growth rate and Ksvalues from flow cytometry totalcounts of bacteria, also obtain maximum BOD utilisation rates and Ksvalue for wastewatersamples.Methodology:Kinematic parameter to design active sludge plant and methodology of obtain kineticparameters .The important kinetic parameters requires for process design include asfollowing:Y: The cell of yield co-efficient define as the mass of activated sludge per unit of substrateremoval (mg VSS/mg COD)Kd=Theendogenousdecayrate(1day)μmax=themaximumSpecificgrowthrate(1day)Ks=ShapefactorofMonodequationIn order to find specific growth rate following formula used.2|P a g e
Monod equation:μ=μmaxSKs+SWhere, S = Subtraction concentration (mg/L)The following graph plot from the given data of BOD and time duration in order to find theexperimental growth rate and model growth rate. To fine the value of experimental growthrate of individual BOD, that obtain by the equation of line of individual graph rate. The slopevalue indicate value of growth rate.(Molinos-Senante, M,et. al. 2017)The above graph have individual growth rate at respectiveBiochemical Oxygen Demandwhich areμ3000=0.0101,μ2000=0.0211,μ1500=0.0143,μ600=0.0022,μ400=0.014,μ100=0.008perday.In order to find the model growth rate, it is require to use experimental growth rate to obtainmodel growth rate by following formula:(Modelgrowthrate)3000=μmaxxBODKS+BOD¿0.43754095x150052.43312146+1500¿0.422763091day(Modelgrowthrate)2000=0.43754095x100052.43312146+1000¿0.415742284/day(Modelgrowthrate)1500=0.43754095x75052.43312146+750¿0.408950857/day(Modelgrowthrate)600=0.43754095x30052.43312146+300¿0.372445939day3|P a g e
